I installed the trial version, so i can check if it's good for me.
(i already buy the full version)
And I think you're wrong with logic.
These two options I marked, are exactly the same.
Every time "MACD IS LESS THEN SIGNAL" it necessarily means "HISTOGRAM IS LESS THEN ZERO".
And the same in the opposite situation.
I was looking for a signal that would only be given while crossing the zero line, and I see that this tool does not support this (maybe because of a mistake in logic).
I think this is a very basic signal that should be in such a tool, because that is the basis of MACD.
