View API DocsThe backtester runs a day-by-day portfolio simulation using real EOD options prices — not synthetic approximations. Open, hold, and close positions exactly as you would in a live account, then inspect every row of the results.
Choose from 20+ pre-built strategies in the Simple Backtester wizard, or build any arbitrary multi-leg strategy in the Advanced mode. Both modes expose the same underlying engine and produce the same detailed output.
Real mode buys at the ask, sells at the bid, trades whole 100-share contracts, and deducts your broker's per-trade and per-contract fees. Ideal mode uses midpoint pricing and fractional contracts — useful for quick strategy validation before committing to real-mode figures.
Historical distribution of returns on options contracts by moneyness, type, and days-to-expiration — built from real EOD data across thousands of tickers and years of history.
