Hello!
I'm a total beginner... The code below finds a MACD Divergence when the height of B is no more than 1/2 the height of A (see image in the link below). No matter what I try, I cannot find a way to make the code find the divergence only when also C is no more than 1/2 the height of A. Anybody can help me with this?
