Option marks are theoretical, not historical quotes. The XSP 0DTE mode uses a modeled intraday path, fractional time to expiration, strike-dependent IV skew, and European cash settlement at the regular-session close. It does not reproduce a real option chain.

Session type Underlying Any supported stock, ETF, or XSP. Position setup Existing-trade mode changes cost basis and option calibration, not the selected underlying movement engine. Starting underlying price Simulated/replay clock: leave this blank so Outlytic uses the observed XSP price at the selected time. Current clock: enter your brokerage price for an exact live anchor. Path model Controls the shape of random shocks. 0DTE movement engine Original preserves the exact v1.0 calculation. Classic smooth uses restrained Gaussian steps calibrated to today's session. Realistic samples recent observed one-minute returns. Starting IV (%) Intraday clock Current ET must be inside the regular session. Simulated start time Default step IV skew Session volatility Scales the selected movement engine without changing its core behavior.
