I would like to give an idea for CD, in line with what other platforms do.

The display is called the volume imbalance and it compares the contracts not on the same price, but diagonally, because that is how the offer meets the demand.

Then on these platforms the volume imbalance can be displayed in candles also that not only refer to the Time Frame but for example to a certain number of ticks or a fixed number of contracts for candle.

This video of MD explains everything: https://www.youtube.com/watch?v=pgnN_2p_uuo&t=301s
