MarS is a financial market simulation engine powered by a generative foundation model, developed by Microsoft. It provides tools for simulating order flow, analyzing stylized market facts, forecasting, and studying market impact.

Use cases

  • simulate financial market order flow with a generative model
  • forecast future market dynamics via simulation
  • analyze market impact of large orders
  • generate stylized facts reports for simulated markets
  • run interactive market simulation demos
  • research market microstructure with deep learning

When to choose

  • you need to simulate or forecast financial market dynamics with ML models
  • you are researching market microstructure or order agent behavior
  • you want to study market impact of trades in a simulated environment

When to avoid

  • you need production trading or live market execution
  • you require the pretrained model immediately, as it is still pending public release
  • you work outside financial market simulation domains
