A research coach that backtests a trading rule on free data, locks a held-out test, and labels results DATA VALIDATED, TRADE-OFF or NO EDGE.
Our review
3/5our rating
We like the honest 'NO EDGE' label and that it never trades. Free Yahoo data limits how far to trust it.

Template description
Research-coach pattern: question → backtest on free Yahoo data → locked held-out finding → parameter sweep → paper (you click). Labels DATA VALIDATED, TRADE-OFF, or NO EDGE. Any classic rule — not SPY-only. Educational; never trades.
