Thanks Vonasi, yesterday I thought I had done your first suggestion and tried the tradeon = 1 and still got an optimisation window as per this screenshot below?
Only way I could get it to stop was to Rem it out, so thanks for the extra code above.
The question though, is why is the VRT code giving different results compared to a non VRT system with the same code? First two images here from my previous posts above: https://www.prorealcode.com/topic/machine-learning-in-proorder/page/15/#post-127605
