I agree about the MA use, it lags. Which is why I use several different time periods along with volume to signal entries and exits. Remember with candles that only the last candle is real, what is happening now is still forming and won't be actual until the last trade closes in that time period. Recently I have been watching candle formation with a countdown timer so that I know how much time is left before the candle is complete. I really want to know about time remaining. I find it useful.
Wouldn't you want to involve volume in that calculation somewhere? IE if it starts to trend one way on low volume that may be an indication of a headfake
