Delta Strength Suite Wiki
Live Order Flow — Indicator Reference & Interpretation Guide
Traditional delta measures the imbalance between aggressive buying and selling. Delta Strength adds another question:
What did that pressure actually accomplish?This wiki explains the eight Delta Strength tools, their displays, settings, states and relationships. Each chapter follows the same structure, so you can read it end to end once and then return later to look up a single display, label or setting.

CHAPTER 00
Delta Strength Overview
What is Delta Strength, and why are there eight tools?
What it does
Regular delta only tells you one thing: were the aggressive buyers or the aggressive sellers bigger on this bar? That is useful, but it is not the whole story. Two bars can show the same delta and still mean very different things.
Delta Strength asks a better question: did that pressure actually get the job done? Was the pushing strong or weak? Did it keep going or fade? Did price move the way that pressure should have moved it, or not?
One picture cannot answer all of that at once. So the answer is split into eight tools. Each looks at the same pressure a different way — right now, inside the current move, across the whole session, next to price, and so on.
The eight tools
Pressure right now.
Pressure inside the current move.
Pressure compared with price.
Pressure added up over the session.
Is the pushing side getting paid?
How this move compares with past moves.
Did price accept or reject a level?
Is a push getting stronger or weaker?
How to use the suite
All eight tools start from the same Delta Strength information. Each one looks at it in its own way. That is why two tools can disagree without either one being wrong — they are answering different questions.
Do not count how many tools are green or red. Ask whether the different views are telling a story that fits together.
One rule holds for the whole wiki: read each tool for what that tool shows. ZigZag lines, price boxes and other drawings you may see on a chart come from separate tools. We never use them to explain a Delta Strength display.

CHAPTER 01
Flow Ribbon
What is Delta Strength pressure doing right now?
What it does
Flow Ribbon shows live pressure. Instead of one delta number per bar, it tracks three Delta Strength lines — fast, medium, and slow — and shows how they line up and how far apart they are.
It is a picture of the character of the pressure. It is not a running total, and it is not the distance price has travelled.
What you see
The status line shows two readings, and they are separate. Read both.
The side that is currently qualified — Bull or Bear. It stays for a short memory after it was last confirmed, and reads neutral when no side qualifies.
What the three lines are doing: Compression (moving closer), Transition (no clean line-up), Expansion (spreading apart with a confirmed side), Re-acceleration (spreading apart again the same way), or Failure (a confirmed flip). It reads Invalid while warming up.
Direction and Phase are two different things. Bull + Compression is normal: the bullish side is still in force while the lines squeeze together. It does not mean bearish, and it does not call a reversal.
How to read the display
- Two edge lines with a colored fill — the top and bottom of the three references. The gap between them is how far apart the lines are. The fill color follows the qualified direction.
- Status line — for example Phase=COMPRESSION Dir=Bear Valid=1. It names the phase, the direction, and whether the data is valid.
- Pulse markers — a Re-acceleration or a Failure event. Each fires once.
Why this can look confusing
People expect a wider band to mean stronger pressure. It does not. A wider band just means the three lines are farther apart. Read the gap together with the Direction and Phase words, not on its own.
Advanced detail — timing
The Flow Ribbon updates from finalized Delta Strength states. Each bar's Direction and Phase are set once, when the bar closes, and old bars are not rewritten later. Memory and pulses clear at the start of the configured trading session.
Common mistakes
Mistake
“The band is widening, so price must keep going.”
Correction
A wider band means the three lines are farther apart. It is information about pressure, not a promise about price.
Mistake
“Compression means a reversal is coming.”
Correction
Compression means the lines are squeezing together. It can open back up the same way, flip, or keep going with less pressure.
Mistake
“Flow Ribbon tells me why price moved.”
Correction
It tells you what the pressure was doing. It does not explain the reason for a move.
How it fits with the suite
Flow Ribbon is the "right now" layer. It does not tell you how much pressure has built up in the current move (that is Leg Pressure), what the whole session has added up (Session Pressure), or how pressure compares with price (PPO).
Quick reference
- Direction
- Bull, Bear, or neutral — the qualified side.
- Phase
- Compression, Transition, Expansion, Re-acceleration, Failure.
- Band width
- How far apart the three lines are — not pressure size.
- Bull + Compression
- A normal reading, not a reversal.
CHAPTER 02
Leg Pressure
How much pressure has built up inside this move?
What it does
A "leg" is one move between turning points. Leg Pressure adds up the Delta Strength inside that move. A positive total means bullish pressure is building in the leg; a negative total means bearish pressure is building.
Why add it up inside the leg? One bar on its own is hard to judge, and a whole-session total is full of old history that may not matter now. Measuring inside the leg gives the current move its own scorecard, so you can compare it with the last one.
What you see
- A signed curve — the running Delta Strength total for the leg. Green above zero (bullish), red below (bearish).
- A cyan diamond — a confirmed turning point. In Confirmation mode the curve resets to zero here. It is not a buy or sell marker.
- A mode label — which anchor the curve is using (below).
Two modes — and the important timing idea
The Leg Anchor Mode setting picks where the count starts. Both modes are the same tool; they just start at a different point, so they can read differently at the same moment.
Starts counting at the bar where the turn is confirmed, and only counts forward. It answers: how much pressure has built since the turn was known?
Shows the completed leg starting from the earlier high or low that later became the turning point.
Here is the tricky part, said simply: at the moment of that earlier high or low, the software did not know it would become the turning point. It learned that later, when the turn was confirmed. Apex mode then draws the leg from that earlier point — but that labeling happens after the fact. Confirmation mode avoids this by starting only at the confirmed turn.
Why does Leg Pressure keep going back to zero?
In Confirmation-Anchored mode, every cyan diamond marks a newly confirmed turn. The old measurement ends there and a new one starts. Nothing was erased and nothing repainted — the tool simply began measuring the new leg.
Common mistakes
Mistake
“Apex is better.” / “Confirmation is better.”
Correction
They answer the same question from different starting points. Neither is more accurate.
Mistake
“The curve reset — it repainted.”
Correction
A reset at a confirmed turn is the design. It starts a fresh count; it does not rewrite the past.
Mistake
“A big reading is a trade in that direction.”
Correction
The size is how much pressure built in the leg. Compare it with what price actually did.
How it fits with the suite
Flow Ribbon is pressure right now; Leg Pressure is pressure added up through the move. PPO compares pressure with price. Absorption asks whether the effort got paid.
Quick reference
- Measures
- Delta Strength added up inside the move.
- Confirmation-anchored

- Cyan diamond
- Confirmed turn; the curve restarts.
CHAPTER 03
Price Pressure Oscillator
How is Delta Strength changing compared with price?
PPO compares two things. It is not a plain up/down direction tool. Almost every PPO mistake comes from reading it as one.
What it does
PPO compares how Delta Strength has been changing with how price has been changing. It also compares each one with what has been normal for it recently. Then it reports the difference.
- Above zero — Delta Strength is stronger than price right now. That can mean more positive than price, or less negative than price.
- Below zero — Delta Strength is weaker than price.
Because it is a comparison, some readings look backwards at first and are completely normal. Price can fall while PPO rises (Delta Strength is falling less than price). Price can rise while PPO falls (Delta Strength is not keeping up). Showing those disagreements is the point.
The five States
Separately from the line, PPO sorts each bar into one of five States. It uses the price change, the Delta Strength change, and the smoothed line. It does not use the line's up/down slope.
Price and Delta Strength are both pointing up together.
Price and Delta Strength are both pointing down together.
Price looks weak, but Delta Strength is stronger than price alone suggests. It does not claim big players are buying.
Price looks strong, but Delta Strength is weaker than price alone suggests. It does not claim big players are selling.
No clear relationship qualifies right now. Neutral is still information.
State versus Strength
The State says which relationship is present. Strength (0 to 3) says how strongly it qualifies, shown as the shade of the column — darker is stronger.
Strength is not a probability
A 3-out-of-3 reading is not a 100% chance, not a win rate, and not an automatic entry. It just says the relationship qualifies strongly right now. It says nothing about the future.
There is also a third output, Bias: +1 for Bull Confirm and Accumulation-Like, −1 for Bear Confirm and Distribution-Like, 0 for Neutral. Bias is directional context that automation can read. It is not a buy or sell signal.
What you see
The smoothed PPO reading — the main line to watch.
PPO Raw — the same reading before smoothing. Quicker but noisier. Single spikes are not instructions.
The balance point of the comparison. Not a buy or sell line.
The State for that bar. Shade = Strength.
Neutral, or warm-up, or a held State at Strength 0 — see below.
Three things that are always true
1. The line's sign is not the State. A red Bear Confirm column can appear while the blue line is still above zero, and the State can change without the line crossing zero. 2. The line's slope is not the State. 3. An empty column is not always Neutral. A State can stay active while its Strength drops to 0, and at Strength 0 no column is drawn.
How the States start and stop
A new non-neutral State must qualify before it is shown, so brief candidates are not painted. Once a State is active, it can remain in place after the original condition weakens — even at Strength 0, where nothing is painted. It ends when its hold condition no longer qualifies. Because of this, a State can change while the line barely moves (the price side changed), and the line can move a lot while the State stays the same.
Advanced detail — timing
Each bar's PPO line, State, Strength and Bias are set when the bar closes and are never changed later. Old PPO columns do not repaint. PPO's own math restarts at the change of calendar date — a different reset from Session Pressure.
Example — the technical deep dive
The strongest lessons on this chart:
- Sign is not State. Around 1:28 and 1:57 there are red Bear Confirm columns while the blue line is still above zero. The State does not need the line to cross zero.
- A moving line is not a State. From about 1:13 to 1:16 the blue line rises two full points, but no column appears.
- State can change while the line is flat. Near the high around 1:25 the columns switch from green to teal while the line holds near the top. Price eased off, so the comparison changed even though the line barely did.
- Disagreement, at full strength. From about 2:00 to 2:04 price rallies while the blue line falls toward the bottom and the columns are the deepest amber — a strong Distribution-Like reading. Darker means it qualifies more strongly, not that a reversal is more likely.
The full section-by-section walk-through lives in the internal reference notes. On this page, use the chart to practise the reading order above.
Common mistakes
Mistake
“PPO is above zero, so it is bullish.”
Correction
Above zero means Delta Strength is stronger than price right now. Read the State.
Mistake
“The line turned up, so it is Bull Confirm.”
Correction
Slope by itself does not set a State.
Mistake
“No column means Neutral.”
Correction
It can also be warm-up, or a State that is still active at Strength 0.
Mistake
“Accumulation-Like means big players are buying.”
Correction
It means Delta Strength is stronger than weak price suggests. The software does not know who is trading.
Mistake
“These States have nothing to do with direction.”
Correction
They carry a directional bias as context. They are not buy or sell signals by themselves.
How it fits with the suite
PPO is the only tool that compares Delta Strength with price. Leg Pressure measures pressure inside a move, Session Pressure adds it up over the session, and Absorption checks whether the pushing side got paid. PPO's job is agreement and disagreement.
Quick reference
- Blue line
- Smoothed PPO.
- Gray line
- PPO Raw — quicker, noisier.
- Zero line
- Balance of the comparison.
- Above / below zero
- Delta Strength stronger / weaker than price.
- States
- Neutral · Bull Confirm · Bear Confirm · Accumulation-Like · Distribution-Like.
- Strength
- 0–3, shown as shade — not a probability.
- Empty column
- Neutral, warm-up, or a held State at Strength 0.
CHAPTER 04
Session Pressure
What has Delta Strength added up to during this trading session?
What it does
Session Pressure is one running total. It adds up Delta Strength from the start of the current trading session. Where Leg Pressure forgets at each turn, Session Pressure keeps remembering, so it works as a backdrop: it tells you where the session has been.
There is no smoothing, no special math, and no price mixed in. It is just the session total.
What you see
The panel is centered on a zero line. Above zero the session total is positive; below zero it is negative. Read two things separately:
Is the total positive, negative, or near zero right now?
Is it rising or falling right now?
Level and trajectory are different. The total can be negative and rising (still below zero, but improving) or positive and falling (still above zero, but weakening). Reading only one of them is the most common mistake here.
Reset
Session Pressure resets to zero at the start of the configured trading session. The exact clock time depends on the NinjaTrader trading-hours template on your chart, so it is not a fixed time of day. On the chart the reset looks like a sharp drop back to zero and a break in the line, and then the total starts building again.
A reset is not a selling event
That sharp return to zero at the session boundary is the reset. It is not a sudden burst of pressure.
How to read it
A positive total does not promise price will rise next, and a negative total does not promise price will fall next. It is a backdrop. The total can stay negative right through a price bounce, because it still carries the earlier part of the session. A zero crossing means the running total changed sign — it is not a forecast.
For short-term traders, a positive-but-fading or negative-but-rising reading is useful context on whether the session backdrop is with you or against you. It is context, not a prediction.
Common mistakes
Mistake
“There are 30-minute and 60-minute views.”
Correction
There are not. Session Pressure is one session total with no horizon setting.
Mistake
“It is negative, so pressure is still getting worse.”
Correction
A negative total can be rising. Level and trajectory are different.
Mistake
“The drop to zero at the session boundary was a big selloff.”
Correction
That is the session reset, not a pressure event.
Mistake
“Green means buy, red means sell.”
Correction
Color shows the sign of the running total. It is not an instruction.
How it fits with the suite
Flow Ribbon is pressure now. Leg Pressure is the current move. Session Pressure is the whole-session backdrop. PPO compares pressure with price.
Quick reference
- What it is
- One running Delta Strength total for the session.
- Level
- Positive, negative, or near zero.
- Trajectory
- Rising or falling right now.
- Reset
- At the start of the configured trading session.
CHAPTER 05
Absorption Meter
Is the side that is pushing getting paid for its effort?
What it does
Absorption Meter compares effort with payoff. Given how much Delta Strength effort a side is spending, how much favorable price movement did it actually get? A lot of effort with matching progress is efficient. A lot of effort with poor progress is different — and when the shortfall is real and keeps going, that is absorption.
Small effort with little movement is not absorption. There has to be real effort first for it to be absorbed.
Active side
The header always names the active side — BUYERS or SELLERS — meaning whose effort is being measured. The active side is not the same as the market implication. Either side can be paid, or either side can be the one getting absorbed.
Do not conclude
"Active side: buyers" does not mean bullish, and "active side: sellers" does not mean bearish. It only tells you whose effort is being measured. Buyers being absorbed is bearish context; sellers being absorbed is bullish context; neither guarantees a reversal.
The states
Not enough history yet.
The active side is getting reasonable price movement for its effort.
The active side is still pushing, but the payoff is getting worse. Early evidence, not confirmed yet.
The payoff failure is now strong enough to count as confirmed absorption. Named for who is being absorbed: sellers absorbed shows as Accumulation, buyers absorbed shows as Distribution.
The campaign has failed under the tool's own rules — a different point in the lifecycle from confirmed absorption.
A payoff gap is not automatically absorption
Blue below gray means the payoff is behind. Confirmed absorption needs the full set of conditions — real effort, a payoff shortfall that is big and lasting, and the side still pushing. Do not read every gap as confirmed absorption, and do not treat Segment Failure as the same thing as Building.
Two modes
Splits activity into buyer or seller campaigns and compares actual payoff (blue) with an expected payoff (gray) inside the current campaign. A new anchor starts a new campaign with a fresh account.
Compares actual payoff with a range built from past completed campaigns only. The current campaign is left out of its own reference and future campaigns are never used. It is not a rolling one-week window.
Two different color systems
ZigZag: the fill color shows the campaign State — green = EFFICIENT, amber = BUILDING, red = confirmed absorption, purple/neutral = SEGMENT FAILURE, and gray = CALIBRATING. ContinuousDS: green means actual payoff is above the historical band and amber means it is below the band. Do not use the ContinuousDS color key to interpret the ZigZag panel.
In the ContinuousDS view the gray band is the middle range of past payoffs and the faint line is the middle (median) outcome. Green means the payoff is above that range; amber means below it. A ContinuousDS campaign keeps going across same-side turns and only ends when the active side changes, so this panel shows fewer boundaries than the ZigZag panel.
Two things the colors are not
The gray band is payoff history inside the ContinuousDS panel — it is not support or resistance and does not come from price levels on the chart above. Also, green does not mean buyers and amber does not mean sellers. In ZigZag, the fill shows the campaign State. In ContinuousDS, green/amber shows payoff above/below the historical band. The header identifies which side is active.
How to read Accumulation and Distribution
ACCUMULATION means seller-directed effort has been absorbed strongly enough to meet the Meter's confirmed-absorption rules. DISTRIBUTION means buyer-directed effort has been absorbed strongly enough to meet those rules. The name describes which side is being absorbed; it does not identify an institution or guarantee the next move. SEGMENT FAILURE is a separate campaign outcome and should not be read as the same thing as confirmed absorption.
Common mistakes
Mistake
“Green means buyers, amber means sellers.”
Correction
No. The header names the active side. ZigZag fill color shows the campaign State; ContinuousDS green/amber shows payoff above/below its historical band.
Mistake
“Blue below gray is confirmed absorption.”
Correction
That is a payoff shortfall. Confirmed absorption needs the full set of conditions.
Mistake
“The gray band is a support/resistance zone.”
Correction
It is a history of payoffs inside the panel, not a price zone.
Mistake
“ContinuousDS uses about a week.”
Correction
It uses all past completed campaigns available in the loaded history.
How it fits with the suite
Every other tool measures pressure. Absorption measures what that pressure bought. It is most useful next to Leg Pressure and Leg Ledger, which say how much pressure was applied in the first place.
Quick reference
- ZigZag mode
- Actual vs expected payoff inside the current campaign.
- ContinuousDS
- Actual payoff vs the range from past completed campaigns.
- Blue / gray
- Actual payoff / expected reference.
- ZigZag fill
- Campaign State: EFFICIENT / BUILDING / confirmed absorption / SEGMENT FAILURE / CALIBRATING.
- ContinuousDS green / amber
- Actual payoff above / below the historical band.
- Active side
- Whose effort is measured — not a direction call.
CHAPTER 06
Leg Ledger
Is the current move strengthening, weakening, or being eaten by the other side?
Leg Ledger is the memory layer. It remembers past moves so you can compare the current one with them.
What it does
Most displays show what is happening now. The Ledger also remembers completed moves, so you can compare the current move with the ones before it. "This push is strong" only means something next to the pushes that came before.
What you see — current vs last completed
The Ledger shows two different things at once. Mixing them up is the most common source of confusion.
Direction plus a health word: developing, building, healthy, strong, weakening. This is the move happening now. It reads TRANSITION when the direction is unresolved.
A look back at the move that just finished: advancing, stalling, threatened, range, insufficient.
A current bearish reading can sit next to a "last completed: bullish" reading. That is not a contradiction — one is now, the other is what just ended.
STRUCT and the LIVE bar
How big the current live move is compared with the tool's structural reference. A higher number means a bigger-than-usual live move. It drives how intense the Gas ribbon looks on that bar.
The move happening right now, drawn as an outlined bar. It can still change until the move finishes, so it is not counted as finished history yet.
IMP and CONS
Impulse comparison: how this finished push compares with the previous push in the same direction. Here, about 1.87 times as big. It compares Delta Strength, not price distance.
Consumption: how big the counter-move was compared with the push it fought against.
CONS can go over 100%
CONS 125% is valid. It means the counter-move was bigger than the push before it. Consumption is not capped. It is strong evidence, but it is still not a probability or a win rate.
Gas ribbon
Bullish effort.
Bearish effort.
Deeper is stronger current effort. No number is shown.
Setup and history
Practical setup
Tick Replay: on. The Continuous Gas setting needs several finished regular sessions before it is ready — about 7–10 sessions is practical, and 14 is plenty. You do not need 30–200 days; extra history just makes the chart slower to load. The Normal Gas setting uses a built-in calibration and needs no history.
"Insufficient" does not mean "load more days"
It means the most recent finished comparison could not be made safely — for example there was no valid earlier push to compare with. It can show up with plenty of history loaded, and the protection is on purpose.
Common mistakes
Mistake
“CONS 125% is impossible.”
Correction
Consumption is not capped. Over 100% means the counter-move was bigger than the push before it.
Mistake
“IMP x2 means price should travel twice as far.”
Correction
IMP compares Delta Strength, not price distance.
Mistake
“The LIVE bar changed — it repainted.”
Correction
The live move is meant to change until it finishes. Finished bars do not change.
Mistake
“Last completed says bull but the current line says bear, so it's broken.”
Correction
Last completed is history; the current line is now.
How it fits with the suite
Leg Pressure measures the move in front of you; the Ledger remembers the moves behind it. Absorption asks whether that effort was paid.
Quick reference
- Current line
- Direction plus health — the move now.
- Last completed
- The move that just finished.
- STRUCT
- Current live move vs the structural reference.
- LIVE
- Outlined current move; can still change.
- IMP / CONS
- Push vs prior push / counter-move vs push (may exceed 100%).
- Gas ribbon
- Green bullish, red bearish, deeper shade stronger.
CHAPTER 07
Level Verdict
Did the market accept or reject the level it tested?
What it does
Level Verdict watches what happens after price pushes past an important level. Touching a level is not enough, and poking through it for a moment is not enough. The tool asks whether the market could actually settle on the other side.
The break is the attempt. The verdict is the result.
What levels are tested
The shipping setup tests Donchian levels — the highest high and lowest low over a chosen number of bars. That gives a clear upper and lower line for price to try to break. The red ZigZag you may see on the price panel is a separate tool and does not create these verdicts.
The verdicts
Accepted. The break held.
Rejected. The break failed to hold.
Contested. No clean accept or reject. Neutral, and a valid result.
Hollow. The break had weak Delta Strength behind it. A quality note, not a direction and not a fourth verdict.
The correction that matters most
ACC does not mean bullish and REJ does not mean bearish. The verdict word says what happened to the level; the direction of the break says the market meaning. Accepted lower prices are bearish; rejected lower prices are bullish.
The four cases
| Break | Verdict | Meaning | Implication |
|---|---|---|---|
| Up break | ACC | Higher prices accepted | Bullish |
| Down break | ACC | Lower prices accepted | Bearish |
| Up break | REJ | Higher prices rejected | Bearish |
| Down break | REJ | Lower prices rejected | Bullish |
| Either | CONT | No clean verdict | Neutral |
Marker key
Bullish implication.
Bearish implication.
CONT — contested.
Hollow — weak participation.
An accept in the same direction as the last one — a continuation of the sequence. Not certainty.
What you see
The marker sits on the tested level at the bar where the verdict is decided. Green always points up, red always points down. Once a verdict is decided, that marker stays fixed — it is not changed later because of what price did afterward.
Settings
How many bars set the rolling high and low. Smaller updates levels more often and gives more tests; larger gives fewer, longer-term levels.
How far past a level price must close before a test starts.
How long the tool watches after a valid breach for the market to accept or reject the level before that test ends.
Common mistakes
Mistake
“ACC means bullish.”
Correction
Accepted higher is bullish; accepted lower is bearish. The break direction decides.
Mistake
“H tells me the direction.”
Correction
H is participation quality, not a direction.
Mistake
“A level was touched, so a verdict should print.”
Correction
Price must close past the level and be tested first.
How it fits with the suite
The pressure tools describe what order flow is doing. Level Verdict reports whether the market could actually do business on the other side of a tested level.
Quick reference
- ACC / REJ / CONT
- Accepted / rejected / contested.
- Implication
- Set by the break direction, shown by the marker.
- +ACC
- Same-direction continuation.
- H
- Weak participation — not a direction.
- Settings
- Donchian N · Breach ticks · Test window bars.
CHAPTER 08
Pullback
Is a push getting stronger or weaker?
What it does
Pullback looks at the quality of a push, not just the distance price moved. Price tells you a pullback is happening; Pullback tells you whether the pressure behind it is getting stronger or weaker.
Two pullbacks can travel the same distance and mean opposite things — one backed by growing pressure, the other losing pressure as it goes. That difference is what this tool marks.
The three classes
The directed pressure got stronger.
The directed pressure got weaker.
No real change.
How to read the markers
- Green — a bullish push
- Red — a bearish push
- Filled triangle — BUILD
- Hollow triangle — FADE
- Gray — FLAT
Put together: Green BUILD = bullish pressure strengthening. Green FADE = bullish pressure weakening. Red BUILD = bearish pressure strengthening. Red FADE = bearish pressure weakening.
Two markers on one bar is normal
The up-push and the down-push are watched separately, so one bar can carry both a green and a red marker when both qualify. They are two separate events, not a contradiction. Markers print once at the pullback bar and never move afterward.
Why this matters
Watch the bearish counter-move. Red BUILD means the pressure against you is growing; Red FADE means it is losing force.
Watch the bullish counter-move the same way, using the green markers.
Critical
FADE does not mean an immediate reversal. BUILD does not guarantee the move continues. Green is not an automatic buy and red is not an automatic sell. Pullback is context and trade-management help, not a standalone buy/sell system.
Setup
Tick Replay: on. Let the chart finish loading history before judging older markers. There is no special multi-day calibration, and there is nothing to tune in its logic.
Common mistakes
Mistake
“Build means buy, Fade means sell.”
Correction
They say whether the pressure behind the shown direction got stronger or weaker.
Mistake
“A green Fade is contradictory.”
Correction
Green is a bullish push; Fade says its pressure weakened. Both can be true.
Mistake
“Two markers on one bar is a bug.”
Correction
Both the up and down contexts qualified on that bar.
How it fits with the suite
Flow Ribbon describes live pressure broadly; Pullback grades the change in pressure inside one specific push. Leg Pressure adds pressure up through a move, and Leg Ledger compares finished moves.
Quick reference
- BUILD
- Pressure strengthening (filled triangle).
- FADE
- Pressure weakening (hollow triangle).
- FLAT
- No real change (gray).
- Green / red
- Bullish / bearish push.
- Two on one bar
- Both contexts qualified — not a contradiction.
REFERENCE
Putting the Indicators Together
How PPO, Leg Pressure and Absorption can tell different parts of the same story
These three tools look at the same move in different ways. PPO compares Delta Strength with price over a short window. Leg Pressure adds up Delta Strength since the last confirmed turn. Absorption asks whether the side that is pushing is getting paid. Because they remember different parts of the move, they can disagree — and that disagreement can be useful.
This is not a voting system, and one tool does not cause another. Read them as three independent views and see whether the story fits together.
Five moments worth studying
Price falls fast. PPO shows Bear Confirm. Leg Pressure drops sharply negative. Absorption shows SELLERS active and EFFICIENT — seller-directed effort is still receiving reasonable price payoff under the Meter's rules. Three different measurements, one compatible story.
Price rises. PPO shows Distribution-Like for part of it. Leg Pressure stays negative — bearish Delta Strength keeps building in the leg. Absorption independently shows SELLERS active while their payoff deteriorates. Seller-directed effort is producing poorer payoff, while PPO independently shows Delta Strength failing to keep up with the price rise.
Price rallies to the high. PPO shows Bull Confirm. Leg Pressure turns positive and builds. Absorption shows BUYERS active and EFFICIENT — buyer-directed effort is receiving reasonable price payoff under the Meter's rules. The mirror of the 12:29 drop.
PPO turns Bear Confirm even though its blue line is still above zero. Leg Pressure is still positive. Absorption still carries an EFFICIENT buyer-campaign reading. Nothing is broken: PPO reacts to a newer change, Leg Pressure still remembers the whole confirmed leg, and Absorption still remembers the buyer campaign from its earlier start. They remember different parts of the move.
Price rallies about 3.5 points. PPO reaches a strong Distribution-Like reading. Leg Pressure gets more negative during the rally. Absorption can still show the longer seller campaign as EFFICIENT because the Meter is judging that longer campaign under its own campaign rules. All three can be true at the same time because they measure different parts of the move. What happened next is only a description: price turned back down at the edge of the chart.
The habit to build
When the tools agree, you have a clean, compatible read. When they disagree, ask why — usually one tool is looking at a shorter window and another is carrying more memory. That question, not a color count, is the point of using them together.
REFERENCE
When Did the Indicator Know?
Telling "known at the time" apart from "labeled after the fact"
When you look back at an old chart, something can appear next to an earlier high or low even though the software could not confirm that turning point until later. So always ask one question: did the software know this at the time, or was the earlier move labeled after the turn was confirmed?
Plain-English terms
| Term | What it means |
|---|---|
| Finished bar | A closed bar. Its readings are set once and published in order. |
| Candidate high/low | The running extreme while a move is still going. It can still change. |
| Confirmation (the cyan diamond) | The bar where the earlier high or low is confirmed as the turn. Leg Pressure restarts here; Pullback arms here; the Ledger records the finished move here. |
| Labeled after the fact | After confirmation, the completed move can be drawn from the earlier high or low. That is bookkeeping, not knowledge the software had earlier. |
| Fixed once printed | Level Verdict markers and Pullback markers are set at their bar and never change. |
| Still developing | The Ledger\u2019s current LIVE move can change until it finishes. |
| Held State | A PPO State can stay active after its first reason fades. |
What can change later, and what cannot
Apex-Anchored Leg Pressure between an earlier high/low and its confirmation, and the Ledger\u2019s current LIVE move.
Session Pressure, Flow Ribbon Direction and Phase, Confirmation-Anchored Leg Pressure, every PPO reading, Level Verdict verdicts, and Pullback markers.
Because PPO readings are fixed once the bar closes, a chart reload that re-draws a leg from its earlier high or low does not change the PPO columns underneath it. That is why "the leg redrew" and "PPO repainted" are not the same thing — the second one does not happen.
CHAPTER 09
The Foundation — Original ZTP Delta Strength
Where the framework started, and the question it introduced
What it is
The original ZoneTraderPro Delta Strength indicator was built in 2019 and started the idea the whole suite is built on. Regular delta tells you who was more aggressive. Delta Strength asks whether that aggression actually worked.
What the example shows
| Time | Actual bar delta | Delta Strength |
|---|---|---|
| 13:12 | +152 | Negative |
| 13:16 | +30 | Negative |
| 13:21 | +192 | Negative |
At each of these three bars, the actual bar delta was positive (more aggressive buying) but Delta Strength was negative — the buying was not turning into successful upside. Price then continued lower. Note that elsewhere in the same sequence Delta Strength printed positive readings too; the point is these three specific bars, not the whole stretch.
Historical example only. It does not promise the same relationship will give the same result every time.
CHAPTER 10
TRCF — TICK Context
A separate TICK-based context tool
TRCF is not part of the Delta Strength Suite.
It reads the market's TICK internals, not Delta Strength. It is a separate context tool, and it is not another Delta Strength calculation.
What it does
TRCF turns the recent NYSE TICK readings into two simple ideas: a direction (is the TICK context leaning up, down, or neither) and a confidence in that direction (low, normal, or high). Confidence goes up when the reading is strong, when the direction has lasted a while, and when it has already survived some pushback. TRCF also checks whether price has been moving against the TICK direction — when it has, the context is challenged, and if it is challenged while confidence is low, it flags high turnover risk.
What you see (current version)
Green = TICK context leaning up, red = down, gray = neutral. Darker shade = more confidence.
A separate lane under the ribbon. Thin = challenged; solid = challenged and weak (high turnover risk); nothing = no challenge. A risk flag, not a reversal call.
A TICK extreme in the same direction as the context.
A TICK extreme against the context. Off by default.
A sustained thrust — a caution, not a signal.
An unusually extreme reading — a caution, not a signal.
The marker legend has a row that reads "N — Number = rolling grade." In the current build that number chip is not actually drawn on the chart, so there is no "N" marker to look for.
Timing
TRCF is worked out once per closed bar, using only TICK data from at or before that bar. Its readings and markers are final when the bar closes and do not repaint. It restarts each day and, by default, reads during the regular session.

CHAPTER 11
Setup & Data Requirements
What the framework needs on the chart
Tick Replay
All eight Delta Strength indicators documented on this page require Tick Replay on the supported NinjaTrader chart. Enable Tick Replay in Data Series and let historical processing finish before judging historical output. TRCF is separate from Delta Strength and uses its own NYSE TICK data source.
History by indicator
| Indicator | History guidance |
|---|---|
| Leg Ledger | Approximately 7–10 sessions is a practical setup for the recent-history Continuous Gas context. 14 sessions is acceptable. More history increases Tick Replay initialization cost. Normal Gas uses a stable calibration from the historical research corpus, which customers do not need to replay. |
| Absorption — ContinuousDS | Not a one-week rolling reference. It uses prior completed eligible RTH campaigns from the expanding available historical reference; the current campaign is excluded and future campaigns are never used. |
| Pullback | No special 7/10/14-day calibration rule applies. It needs enough prior structure to form its causal reference sequence. |
Customer-facing modes
| Indicator | Setting | Choices |
|---|---|---|
| Leg Pressure | Leg Anchor Mode | Apex · Confirmation |
| Absorption Meter | Measurement Mode | ZigZag · ContinuousDS |
| Absorption Meter | Anchor Mode (where customer-visible) | Hybrid · Flow Only · Apex Only |
| Level Verdict | Level definition | Donchian N · Breach ticks · Test window bars |
| Session Pressure | — | One session-cumulative rail; no horizon setting |

CHAPTER 12
Quick Comparison
Eight tools, eight different questions
The eight Delta Strength tools are not eight competing signals. Each views the same market through a different analytical question. The purpose of the suite is to combine those perspectives without confusing one measurement with another.
| Tool | Analytical view | Primary question | What it tells you | Do not confuse it with |
|---|---|---|---|---|
| Flow Ribbon | Immediate / live pressure | What is Delta Strength pressure doing right now? | Whether live directional pressure is expanding, compressing, accelerating or changing direction. | A structural-leg total, or a guaranteed continuation signal. |
| Leg Pressure | Structural leg | How much Delta Strength pressure is developing inside this structural leg? | How directional pressure develops through the leg using either Apex or Confirmation anchoring. | PPO or Session Pressure. |
| Price Pressure Oscillator — PPO | Delta Strength relative to price | What is Delta Strength doing relative to price? | Whether DS is relatively stronger or weaker than price, and whether the classified relationship is confirming or disagreeing with price. | Simple bullish / bearish direction from PPO sign or slope alone. |
| Session Pressure | Session backdrop | What has Delta Strength added up to during the configured trading session? | Whether the session total is positive, negative, rising or falling. | A windowed average, or the current structural leg. |
| Absorption Meter | Effort vs. price payoff | Is the active side getting the price payoff its Delta Strength effort should normally produce? | Whether directional effort is being paid efficiently, or whether payoff is under-performing expectation. | A simple buyer/seller direction signal, or an automatic reversal signal. |
| Leg Ledger | Structural memory | How does current and completed structural pressure compare with previous structural moves? | Impulse strength, counter-move consumption, structural condition and Gas intensity. | Probability, win rate or price targets. |
| Level Verdict | Level acceptance / rejection | Did the market accept or reject the level it tested? | Whether an attempted break was Accepted, Rejected or Contested, and the directional implication of that result. | ACC = bullish or REJ = bearish. Break direction determines implication. |
| Pullback | Developing counter-move quality | Is the directional counter-move building or fading? | Whether bullish or bearish pressure in the developing push is strengthening, weakening or flat. | BUILD / FADE as trade direction. Green and red identify direction; BUILD and FADE identify pressure quality. |
Do not count green and red indicators as votes. Read each tool for the question it was designed to answer, then determine whether the independent views are telling a compatible market story.
