I wanted to change the source for 5 Min EMA from Close to Open in PI while plotting the MOving Average Crossover Strategy

As a part of moving average crossover strategy I wanted to plot 5 EMA (High) instead of 5EMA (Close)

After selecting EMA, you get the below popup. Here in the dropdown you can decide to choose between O, H, L, C, Volume

Thanks Nithin for the answer
and also for introducing PI / Kite. Features are really awesome.
Wish you and the entire Zerodha Team success in all your future endeavours…
