Bud, I am not one of the supper techs that van make a database and spreadsheet sing so I’m always reducing to the kiss principle. 1st off in forex we essentially do not have a complete dome so a full picture of the volume is hidden. On the other hand we do have the data to map or observe the volatility of the price action.
What I do is simply get the specific angle of the PA slope between S&R and then the time cycle, with that I still do not have true volume but I do have the momentum force of the move.
sentiment + momentum = trend.
