There was an article in the 90's in TASC magazine that discussed MACD using DEMA and TEMA.
I never pursued it after coding over 10 years ago because ACD on the 15 minute took over along with confirmed zigzag on daily.

Here are the MAs and the MACDs with LSMA thrown in for fun.
I think DEMA is built in to MACD_DEMA but did not check for iCustom call.
MACD_TEMA requires Tema.

On the new build they sometimes stop plotting so might need some work.
