Spot forex doesnt have accurate volume info as there is no central exchange to report the transactions. You might just be seeing the volume from your broker. If you want to study volume pull up the 6E futures and use accurate volume figures. Up to you... The way I am reading your charts, the entries were excellent because they were first tests of reversal areas. Its enough to see it from just price.
it is not absolute volume that is important but relative volume so that is why these volume figures may work. another reason is that my broker may be the market maker trading against his clients or even in league with other market makers
i have been using VPA and PAT but focused more on VPA because i am learning the technique. it has helped me in a huge way to have confidence in the price action and to confirm the trade and manage the trade. Of course most times price action is enough but this is a personal matter and i have been able to trade much better and also it has helped me stop over trading. There are times when the price action does not make sense is too noisy and at that time to have something else to loook at to give some hint at what is going on in the market is invaluable ; if not because of confusion something stupid may be done. Of course at times the market does not make sense,if we look at VPA Or PAT and at such times, only a prayer and waiting for clarity can help
