This is a Money Flow Index oscillating wave indicator that also has preset levels that can be adjusted by the user in the settings. The levels indicate how deep or high the waves are moving to
i use this indicator when scalping and on all time frame charts, i like to watch for certain patterns forming either at the lower levels for longs or at the higher levels for shorts.
This indicator is smoothed for Heikin Ashi candles, and does RSI in the calculation. MFI uses volume and price change.
