Improvement for Footprint chart COT low/high

Hello, please implement the following idea. It is very helpful.

COT is the abbreviation for Commitment Of Traders. There are two COTs: COT High and COT Low.

COT High is cumulative bid/ask Delta starting from the moment when the price makes new high or repeats previous one. It's usually negative.

COT Low is cumulative bid/ask Delta starting from the moment when the price makes new low or repeats previous one. It's usually positive.

COT helps to see buy/sell balance after new price level has been reached.
