Hi Tomasz,
Thanks for a reply, woodie from cci club uses e-signal formula quite
well and we both had IB data with different results using Heikin
Ashi today.
>From what i see HaOpen calculated in e-signal uses (open+close)/2
previous bar and afl formula does it with close only/2??? I am not
afl programmer,
and i don't doubt that afl language is shorter... but could there be
still difference in results cause of HaOpen calculations in both?
tia, Ben
