Numerous software vendors want to claim the order flow is the only thing a trader needs to make a trade. They are wrong.
ZoneTraderPro also has order flow analysis indicators, but there is an inherent issue that those other vendors do not like to address. Order Flow is not a real time indicator. Order flow must occur to be analyzed, and by then, it may be too late to capture a good profit. The other issue with order flow is that price rarely just trades 10 points in a single direction, there is an order flow fight between the longs and the shorts. So how do you pick a side? These trades occurred over a 1 hour period. As illustrated below, the strongest of the ZoneTraderPro Order Flow signals occurred before the 10 point drop, and the black circle indicates extreme volume occurred on that bar. After that signal, which took 2 points off the trade, there was still significant order flow patterns to the buy side.
And here is the point. The real time divergence signals were good for 4, 5 , 6, and 10 points respectively, without having to wait for order flow confirmation. The real time divergences, combined with volume analysis, were the clear and correct answer.
