This indicator is inspired from "HPotter’s TFS: Volume Oscillator" but I have used Heiken Ashi and Hull Moving Average in calculations in order to reduce noise for better trades. The concept is similar to that of On-Balance Volume indicator (OBV). It is calculated according to these rules:
If Heiken Ashi Close > Heiken Ashi Open, Volume is positive
If Heiken Ashi Close < Heiken Ashi Open, Volume is negative
If Heiken Ashi Close = Heiken Ashi Open, Volume is neutral
BAR COLORS
Green Color: Strong Uptrend with good volume supported momentum.
Faded Green Color: Volume is relatively weakening.
Red Color: Strong Downtrend with volume support.
Gray Color: Downtrend negative volume is relatively weakening.
DEFAULTS SETTINGS
Volume length is 30 (Better for timeframes higher than 1H)
Hull Moving Average length is 14 but Linear Regression Curve can be selected with same length
