Indicator stucks

[NinjaTrader_Jesse]

Hello kujista,

Are you certain its that script causing an issue? I don't see anything in its code which would cause slowness.

[kujista]

When I scroll in chart it takes tooo long to render and after that when i click to chart it rerenders and takes a long time..

Hello kujista,

What do you mean by stuck? We would need a more accurate description of the problem in addition to details on how you are determining a problem is happening.
