bgcolor, заливка бара

Good afternoon. I want to visually fill the bar where
the purchase - green
sale - red transaction took place

Tell me the function with an example. so that it can be inserted into any strategy and it displays a vertical line when trading.

how do I add vertical lines in this script?
If there was a purchase - green

Sale - red

//Inputs
ts_bars = input(9, minval=1, title=Tenkan-Sen Bars)
