This indicator colors the volume bars and candles according to the volume traded. The calculation of the heat map zones is done as follows:
how many standard deviations the volume are distant from the average volume?
For a better visual experience, place the borders and wicks of the candles in a neutral color.
Volume indicator judging level of volume per bar accordingly to Volume Spread Analysis rules. It allows either to set static volume levels or dynamic ones based on ratio comparable to Moving Average. Bars are coloured based on ratio or static levels, visually presenting level of Volume (low, average, high, ultra high).
