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.
