Ok, thank you. So I checked the Journal and saw the following errors:
2026.02.27 11:19:26.602 program file added: \Indicators\QQE.ex5. 22477 bytes loaded
2026.02.27 11:19:26.616 2026.02.01 23:01:00 cannot load indicator 'Relative Strength Index' [4804]

2026.02.27 11:19:46.486 OnTester critical error
I thought 'Relative Strength Index' was a standard indicator. Any idea why it cannot load? How do I go about this?
