How do i set Price Markers to False?

I’m sorry, I don’t know why this doesn’t work for you. It should. I use this all the time.

SetPriceMarker = false;” line needs to be in State.SetDefaults in your indicator code.

Open a new chart and add your indicators to the chart with default settings.
It should not show price markers associated with any of the indicator plots.
You may still get price markers from price bars. That can be disabled in Data Series settings.
