OpenPort, an options simulator you can run locally
An MIT-licensed, self-hosted options simulator for practising prop-style evaluations with delayed or user-supplied market data.
- For
- Options traders practising prop-style evaluations
- Worth noticing
- The default feed is delayed 15 minutes, and the site says a simulated pass is practice, not proof.
Field notes
The local Docker setup can retain accounts and chart history in a named volume, while users can choose simulated prices when markets are closed. The site reports performance measurements for an Apple M2 Max and compares its implied-volatility results with Cboe’s published values across specified options; these are project-reported measurements, not an independent audit. Its listed third-party data adapters have only been tested against sample responses, not live credentials.
