POST /crypto/backtest-max

live

Max memecoin backtest: sweeps every take-profit x stop-loss x hold combination (up to 64) of your screen on the same graded pump.fun entries, ranks them on the older 70% and re-scores the winners on the newest 30% they never saw (walk-forward), so curve-fitted settings show up. Up to 21 days, snapshot ages or a preset's live signals.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
