How to Brier-grade your own ML option-pricing forecasts in 40 lines of Python
The article discusses a method for logging machine learning option-pricing forecasts using a simple Python script. It emphasizes the importance of grading probabilistic forecasts, a practice common in fields like sabermetrics and weather forecasting. The provided script allows users to log predictions and compute Brier loss for evaluation after the options expire.
- ▪The article provides a 40-line Python recipe for logging ML option-pricing forecasts.
- ▪It highlights the significance of Brier grading to evaluate the accuracy of probabilistic forecasts.
- ▪The Helium server offers a free endpoint for accessing option-pricing data without requiring an API key.

Sabermetrics figured this out forty years ago. Weather forecasting has done it for a century. Most ML model owners still do not do it.
