cTrader custom Orderflow @ Footprint Indicator

Using the cTrader API i would like to have an simple indicator showing realized bid x ask on price levels as shown on the picture. Just an mvp. it should have accessible through api the last n-bars with bids x asks on price levels + cumulative information ( cum. bids, cum asks, delta , volume, point of control) The visual is not important, my intention is to use it further in cBot
