Heatmap in candlestick

[jxg-source]

Is it possible to add heatmap in candlestick, similar TradingLite?

At the moment, there is no heatmap feature.
However one could be built with the overlay API.
I took a look at https://www.tradinglite.com/
I guess you are referring to the Liquidity Heatmap.

Yes, I will forward it to you.

Cheers! Where do you get your orderbook historical data from?

It would be the orderbook on Binance: https://www.binance.com/en/landing/data
