the chart is empty, so system that i saved is anymore on and working
When I use the term System I mean an auto-coded strategy / bot / algo etc … are you using the term System in the same way?
It is when you expect your System to still be there that I think we need to explore further.
Are you able to put up a screen shot of what you expect to still be there when you … then i back to the workspace?
I just loaded a System then did File, Save as Template 4, then closed Template 4 so I had no Chart at all showing on my platform then I opened Template 4 and the System was till showing.
Is above what you are doing?? Are you sure you are opening the SAME Template that you had saved??
