| Home Source Documentation Installation License Blazingly Fast & Accurate Option Pricing • Implied Volatility • Greeks Python • Java • TypeScript • WASM • Kotlin Vollib is a collection of libraries for calculating option prices, implied volatility and greeks. What makes vollib special is that it is built around Peter Jäckel’s LetsBeRational, an extremely fast and accurate technique for obtaining Black’s implied volatility. LetsBeRational can obtain implied volatility from option prices with as little as two iterations to maximum attainable precision on standard (64 bit floating point) hardware for all possible inputs. Another advantage of LetsBeRational is its fast and accurate implementation of the cumulative normal distribution function. Jäckel’s implementation provides better accuracy across a wider range of inputs, while being two orders of magnitude faster than its equivalent in scipy.stats. Building on this solid foundation, vollib provides functions to calculate option prices, |
