Is it ok to use Thread.Sleep(0) in OnBarUpdate() of an Indicator ?

I ask because the indicator I was using had a lot of plots and this seems to be the reason it would grind NT8 to a halt so that it took several seconds between clicking on a tab to change to that chart... or for a dialog like Data series to pop up.

I added it, so far so good- very responsive NT8 UI and no problems I can see.. but I'm just wondering if anyone can forsee any problems here.. I'm not a C# or NinjaScript expert.

A sleep for 0 millisecond will do nothing. Using a value > 0 will only delay the moment when the buggy/heavy computing stuff will be done, so not useful either. Also it will only delay one thread, not the GUI thread.
Globally a bad idea.

well it seems to have eliminated my responsiveness problems. And cpu usage also drops for ninjatrader (I have several charts open)

Sleep(0) does something, I have used it in other languages in many situations to reduce cpu usage and delays when you're in a loop... it is similar to Yield() but with differences... https://stackoverflow.com/a/16584612/270143

as you can imagine, you don't want to have to wait several seconds or longer (could be 5 or 10 seconds or more sometimes) every time you switch to another chart tab or open a dialog.

I think this problem is not common because most indicators only use a handful of plots.
