I did run this EA on demo, for a couple months, the results are inline with what the creator/author produced.
Just FYI, I did 99.90% BT using tickstory, the performance from Jan1 2020 til Nov 1st 2021 is really good. But then again as you all know real world performance will only be a fraction of BT results.
And also so many EA out there that only perform well in BT because those EA work by reading history data, basically a scam EA. And also if an EA don't run well in BT, well you can forget that it will perform better in real world application.
IMHO:
1. EA don't perform in BT --> Avoid it right away
2. EA perform well in BT --> Need further inspection SCAM or REAL
3. FT in Demo for a few months --> Compare results with BT of the same period and also compare results with EA creator/author account running the same (if Available)
4. Run it on Real Account. Can start initially with small comfortable deposit amount.
