need a second look at my code to avoid error

[junkone]

i am trying to plot the difference between fast and slow ROC.
i cannot figure out why i keep getting this error. Need some help

2025-02-24 6:25:36 PM	Default	Value of property 'FastPeriod' of NinjaScript 'CustomRocspeed' is 0 and not in valid range between 1 and 2147483647.

In my code, i have set it in the SetDefault for the default values
FastPeriod = 7;
SlowPeriod=14;

When does this error pop up for you? I'm trying to use it and it's not happening to me. Have you tried to reset the indicator to ensure it has been updated? Or remove the indicator and put it back on?

i just restarted ninjatrader and it started working .. i was losing my mind for couple of hours.

I've had a code not work and found out it was not updating because I saved a template as the default. Glad you got it working. Also I noticed in your code that you had IsOverlay set to true; and DrawOnPricePanel also set to true. Is that what you wanted? While they were set to true, if I had hit the fixed scale button, it would unusable as a chart because the ROC difference would be so close to 0. I had to set both of these to false to place it in it's own panel. Regardless your code would still put it in the DataBox so it depends on how you use it...
