Fred,
The result is perfectly OK.
=================
Your EO (variable period) is either 3 or 9
So ResX is a sum of last 3 OR last 9 bars of
Cum1 array.
So it resulting sum is equal either upper or lower
line of the channel.
I suggest you to take a piece of paper or Excel sheet and just
'simulate' the inner working of the code.
Best regards,
Tomasz Janeczko
