Pine language expert for indicator on tradingview

I'm interested to add an indicator to TradingView charts that signals the following condition: if the volumes of the Heikin Ashi chart are in green immediately after a volume in red, it adds to the chart an icon with a label containing information on the % change and the count of how many days of volumes on heikin ashi candlesticks occurred before the green.

Pine language (version 5) executable on tradingview.

Attached a screenshot of how I would like it to be, blue arrow indicating the variation of volumes with data.
