We don't have option to impose one indicator to another. If I want to Plot RSI and moving average over RSI, then in moving average settings, There are limited source. If I have applied RSI on my chart then it should be in the source list of moving average.
It is available in Trading View and almost every brokers chart who support Chart iq. But in Fyers, we don't have.
Hope Fyers team will update on my query soon and this is a very useful feature, It should have implemented..
