DislikedYes, this is what made me think of the market profile when you stated this earlier. Wouldn't the accumulation of volume be an obvious requirement for your line? Forgive me, but I am not trying to turn this into a market profile thread.Ignored
Tracking volume in FX is virtually impossible. Lots traded on various platforms would yield various market profiles (footprints) with differing assumptions. Unless you can track all platforms at all times and synthesize that data into a reliable footprint for volume accumulation, then I'm not quite sure how else it would or could be done. We don't have central clearing in FX and there is no Time & Sales data that is relevant to every pool of liquidity in FX.
Y = MX + B. The most important price level of all.
