Indicator plots fill up with values when I change the indicator parameters

New comment

Hi I was wondering if someone could point me in the right direction with this indicator that I built.

It plots fine until I change one of the input parameters. From there the indicator plots get messed up. I've tried everything it seems, but nothing seems to help. Below is the initialize function and some screenshots of the behavior.


Thank you for any help you can offer
