Indicator-Profiler-exception-on-Aroon-oscillator-in-B37

Can you recall what you did to make WL throw this handled exception? Like changing the indicator or DataSet during the run etc.?

I started all over again

Start WL
Start Extension Indicator Profiler
Deselect all indicators
Selection of all oscillators
Double click on RSI (example)
Evaluator Graphic Indicator Value: empty
Click in Evaluator Tab on "Bottom Axis" to change a parameter (any parameter) = BUG

Thanks but I couldn't reproduce using your steps.

maybe a problem with my local settings? i'll try the whole thing later today on another computer.

You can make it happen if you start clicking around while the evaluator is still running. We'll have to prevent that by disabling some buttons probably.

For now, just let the evaluator finish before you start digging in deeper.

Ok. Thanks. But I did not click while the profiler is running...

"Double click on RSI (example)" ... starts an evaluation on RSI.

one more example using SZO

Eugene this could be due to the recent method signature change, did you test in production or in your dev environment?

We possibly just need to release a new build of Indicator Profiler.
