Skeptic

Type your options strategy in plain English. Skeptic interviews you on the fuzzy bits, runs it on real minute-by-minute options data with fills at the actual bid and ask, then tries its hardest to prove you just got lucky: hidden history, rolling windows, 1,000 reshuffles, nudged settings. Most backtesters flatter you. This one argues to make sure you never lose real money. Six runs free, no card.
