Start in plain English. Type "SPY 0DTE iron condor, 16 delta shorts and 5 delta wings, exit at 50% profit or 200% loss" and the AI fills every field below.
16 strategies, ~140 symbols. Condors, flies, spreads, straddles, strangles, and calendars on the most-traded names, SPX to single stocks.
Enter at 9:45, to the minute. Entry and exit are exact clock times. Hold to expiration or step out at 15:55. AM and PM SPX expirations both supported.
0DTE is DTE 1. Days to expiration counts from 1, so same-day options are first-class citizens, out to 30 days.
Per-leg strike control. Target every leg by delta with min and max bands, or set strike widths in points from a reference leg.
Stops that fire intraday. Percent stop losses and profit targets are checked on every minute bar, with slippage and commissions modeled in.
Bring your own signals. Upload a CSV of entry and exit timestamps and the engine trades your signal on real minute-level options prices.

03 · Why intraday precision matters
Intraday mode tracks your position minute by minute, so stops and profit targets trigger when their levels are reached, not just at the end of the day. Strike selection is powered by ORATS smoothed implied volatilities and Greeks, providing more stable, dependable deltas than calculations based on noisy individual option quotes.
See the full story of every trade from entry to exit, whether it lasts a few minutes or multiple days. Both engines live in the same Custom Backtester, so you can choose the right one for each strategy.
Anatomy of a stop-out · one fill from the run above · Jul 24, 2024
stopped out 2:49 PM


A real fill from the QQQ run above, opened in the Trade History view: the condor’s price minute by minute through the July 24, 2024 session. Theta grinds all morning, the market slides after lunch, and the stop fires at 2:49 PM, the minute the loss crosses 200% of the credit received. By the close the same position had lost nearly twice as much: the mark daily bars would have recorded. Every fill from 2022 onward opens like this straight from the trade log.
