Seems you are interested in the HA indicator as well - obviously. Please look:
I found similar signal to HA, but with incredible precision and especially generating much less loosing trades, what is the danger/DD in HA.
Since the systematic behind is like your HA EA, I thought you could exchange in the EA the HA by the indicator I found. Maybe just make sure it close, sell/buy or buy/sell at the signal (I see you have ext. bool Trend Filter - literally signal is suffisent).
Please let me know here if you are interested and I post the indicator, I am looking up the thread few times a day.
(That indicator I found is nothing new, but it is so inconspicuous that one does oversee its power of precision.)
