Data and licensing

OpenK studies historical market and options data. Some of that data is licensed and cannot be redistributed.

Public outputs are limited to derived, aggregate, or illustrative figures. Raw or row-level market data, full-resolution derived arrays, and current model outputs are not published.

Where a figure is illustrative rather than a direct measurement, it is labeled as such. Realized outcomes shown on the site use widely available index price levels.

The exact construction of the models, their features, and their parameters is not disclosed.

Index levels shown on this site are widely available historical closing levels used illustratively. “S&P 500” and “S&P” are trademarks of S&P Dow Jones Indices LLC and its affiliates.
