I'm trying to get the indicator plots to disappear/reappear when clicking the "AVG" and "BANDS" buttons on the toolbar. It works when I manually press F5 or do "Reload NinjaScript"; however, I'd like this to be done automatically. The "ForceRefresh()" in my code does not work. I've also tried "Update()" and even "SendKeys.SendWait({F5})". How is this done? I know it's possible because indicators offered in NexusFi have done this!
