Hi,
I've copied the default NT Pivots indicator into a PivotsPlus indicator and tried to add a 4th Support and Resistance zone (s4 and r4).
But unfortunately it gives an "Index was outside the bounds of array" error in the OnBarUpdate method. I've tried everything but can't seem to figure out the location of the error.
Anybody help?
I can't paste the complete code because it's too long. But basically I just the same as the Pivots indicator as shipped with NT. I only added some S4 and R4 rows.
