Independent quantitative research on free MetaTrader expert advisors.
I collect Strategy Tester reports for free EAs and re-run them under one broker, one server and one spread, then publish the raw numbers and the arithmetic behind every conclusion.
Current set: 372 free EAs, of which 190 closed at least one trade. 82.6% of those 190 lost money, median return -19.3%. The five highest returns (+1041%, +480%, +262%, +206%, +168%) carry drawdowns of 76%, 93%, 96%, 98% and 99% - all five are martingale or grid systems.
A second set of 1,470 accounts: 79.4% never closed a single position. The 295 that produced a measurable result came to a combined net of about -130k.
The dataset is published under CC BY 4.0 with per-file SHA-256 and the parsing code. I also run a forward test of three EAs on a live-tick demo account and publish every order it opens.
