Which Udemy course, there are lots of them?

I did try to learn it from forex tutorial and mostly they identify divergence by the two indicators such as RSI and MACD. Tricky kind that you would have to watch them what the other indicator do compare to the other.

This tutorial even includes the Stochastic https://www.slideshare.net/NetpicksTrading/how-to-trade-regular-divergence-with-macd-rsi-stochastics
And here the other with only MACD and RSI https://forexop.com/strategy/divergence-trade/
