Questions
Is a high rank a profitable strategy?
No. We do not audit backtests. Rank is catalog completeness, not a live track record.
How is this different from the algo trading list?
The algo list is the whole automation aisle. This page is the backtesting-intent shortlist — testers, notebooks and simulation-tagged products.
Do marketplace EAs appear here?
Only when they are published as catalog products. Vendor marketplace aisles stay under /indicators, /expert-advisors and /mt5.
