MACD histogram is below or above zero.

Hi there. I am making an strategy that works when the MACD histogram cross above or below zero. Now I want to know what is the problem of this condition that will not work when I put my variable in one side and the 0 in the other side?

To have the MACD cross you cannot use a value like that, because EA will assume you are talking about the main chart, and 0 is as far to the bottom as you can get

So how can I identify that zero and use it there in the condition?
