Free share-data settings Not connected

Create a free personal Tiingo account, then paste its API token. The token is saved on this computer; Tiingo price rows are used during a run and are not kept afterward.

Or import price history you own

A CSV can stay locally and avoids another Tiingo request. Include Date, Close, and preferably Adjusted Close, Dividends, and Stock Splits.

Optional exact-options connection Not connected

Market Data is optional. It supplies exact historical option chains for recent validation and stays only on this computer.

Not measured

Gradually retain weekly SPY/QQQ chains and held-out contract histories inside the free one-year window. Calibration uses at most 70 credits per New York day and keeps 30 credits untouched for interactive tests.

Real share history plus clearly labeled option estimates works with a free Tiingo connection or complete CSV files you own. No paid option plan is required; retained exact quotes improve the result whenever they are available.

Research only. Long options can lose their entire premium; short puts can lose much of their reserved collateral. Modeled and historical results do not predict future performance. This app does not place trades.
