@leeta, It's called volume profile. It is available as one of tradeviews built in indicators. It has its own tab above marketplace indicators in the indicators section. It has 3 settings, all the volume on screen, all of volume for session, or all of volume for a selected number of candles. It's very useful for spoting support and resistance levels use Ticks per row for best results, spread the word I'd love to see some good public indicators make use of it.
