POST /crypto/backtest

live

Backtest a memecoin strategy before you trade it: your screen filters + exits (take-profit tiers, stop, trailing, time stop) replayed on every graded pump.fun token at 5/15/30/60 min of age, or on a preset's live signal ledger. Win rate, avg/median return after fees, exit reasons, per-day results, best/worst trades. 1-minute bars, stop first.

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