Quantitative Finance Glossary

Definitions, formulas and tested Python reference implementations for market microstructure, execution and statistical-arbitrage concepts. Written for quantitative researchers and AI agents.

Execution & Market MicrostructureTerm ID: vwap

Volume-Weighted Average Price (VWAP)

The ratio of cumulative traded value to cumulative volume over a horizon. The standard benchmark for judging institutional execution quality.

HFT & Order Book DynamicsTerm ID: ofi

Order Flow Imbalance (OFI)

Net buy-minus-sell pressure at the best bid and ask, measured from changes in top-of-book prices and sizes. Short-horizon price changes are approximately linear in OFI.

Time Series & Stat-ArbTerm ID: hurst-exponent

Hurst Exponent (H)

A scaling exponent that measures long-range dependence in a time series. H < 0.5 indicates mean reversion, H = 0.5 a random walk, and H > 0.5 a persistent, trending series.

Factor Research & Alpha EvaluationTerm ID: information-coefficient

Information Coefficient (IC)

The cross-sectional correlation between a factor's values and subsequent asset returns. Rank IC, its mean and ICIR are the standard first test of whether an alpha factor predicts returns.
