What technical indicator are you actually using? It looks like the implementation of MACD but stopped halfway? Could you like me to a wiki explaining what your indicator is?

Yeah that looks like someone that wanted to use MACD and forgot a part.

I would refrain from using that method as I have doubts that it is more efficient.
Also look at how much more responsive the MACD crossover is vs regular EMA crossover.
