lock in scaling

[Alley]

Hi, I have done a custom study, layering a %DS and Klinger(KVO) indicator onto each other. My problem is trying to lock in the scaling. I have gone to property studies and ticked off no scale and no display, but the indicator still moves around. I want it to lock in at the 50 line. Also with the KVO indicator is there a way to modify the trigger line.

Thanks
