This volume script uses a Z-Score based filter to identify statistically significant high and low volume conditions.
It also includes a variation of LazyBear's obv_oscillator to map volume flow.
Regular volume will appear either lime or red.
Irregularly high volume will appear bright lime / bright red.
Irregularly low volume will appear white.
It comes with tested pre-defined thresholds and lookback lengths, but feel free to play with the settings on your own.
Enjoy!
