# Market Microstructure
## Overview
Study the micro-level mechanisms of price formation: who is trading, how they are trading, and how trades affect prices. For quantitative strategies, this matters because it improves transaction-cost estimation, identifies informed trading, and optimizes execution.
Applicable scenarios:
- Precise estimation of strategy trading costs (instead of simply assuming a flat 0.1% fee)
- Designing large-order execution strategies (`TWAP / VWAP / IS`)
- Detecting order-flow toxicity (avoid time windows dominated by informed traders)
- Quantifying liquidity risk (flash-crash warning)
- Capturing China A-share-specific microstructure features (call auction / closing auction / block trades)
