Open-Source Options Tools for Earnings Vol

Not financial advice. Verify claims independently.

IV crush calculators, GEX estimators, and backtesting libraries — all free, all auditable.

For the DIY options quant, the open-source toolkit:

  • vollib — Black-Scholes, implied vol, greeks in Python
  • QuantLib — the industrial-strength pricing engine
  • py_vollib — Python bindings
  • GARCH libraries — vol modeling, 'arch' package
  • vectorbt — backtest earnings strategies fast

Use case this week: pull MU's options chain from a free API, compute implied vol with vollib, compare the straddle price to the ~9% implied move — you've rebuilt the $200/mo tool's core feature for free.

Then run the actual trade on Stock Picks.
