It seems the macd line being above the zero line denotes a good solid long trend and vise versa. The zero line seems to act as a 50 ma. The signal and macd line seem to act as a 10 and 20 ma.
DislikedHi Pipping,
The MACD has to be above signal for long and below for short.
The histogram will be positive for long and negative for short.
I do not take into account if MACD line is above/below the zero line.
Hope that answered your question.Ignored
