I am not sure exactly why either,eduarescobar wrote: Fri Feb 23, 2024 12:57 am I have this error in expert window.... cannot load indicator 'Stochastic Oscillator'...
I think it was because historical data could not be loaded.
When I first started using MT5, I often got this error.
Now that error no longer occurs.
Please load historical data.
For MT4, I introduced a tool to load historical data in post#1,
Please load MT5 in the same way.
