Trading and Exchanges: Market Microstructure for Practitioners

by Larry Harris

Overview

Published in 2003 by Oxford University Press as part of the Financial Management Association Survey and Synthesis Series, this 657-page book by Larry Harris (USC Marshall School of Business, former Chief Economist of the SEC) is the most comprehensive practitioner-oriented text on market microstructure.

Key Topics

  • The Trading Industry: Market structures, exchange organization, types of traders (informed, uninformed, liquidity, parasitic), and the economics of trading.
  • Market Structure: Order types, order matching rules, price priority, time priority, and how different market designs affect outcomes.
  • Information and Prices: How prices incorporate information, the role of informed traders, and why liquidity traders lose to informed traders on average.
  • Transaction Costs: Bid-ask spreads, market impact, timing costs, opportunity costs, and how to measure and minimize total execution costs.
  • Strategies: Various trading strategies classified by the trader's informational advantage (or lack thereof), time horizon, and market conditions.
  • Market Regulation: Why markets are regulated, regulatory frameworks, and the ongoing tension between efficiency and fairness.

Significance

Harris bridges the gap between academic market microstructure (theoretical models) and practical trading. The book is essential reading for: institutional traders seeking to minimize execution costs, algorithmic strategy designers, exchange officials and regulators, and any serious trader seeking to understand the mechanics behind price formation.

Practitioner Focus

Unlike O'Hara's theoretical treatment, Harris focuses on practical implications. He explains not just how markets work in theory but how traders actually behave and why, providing actionable insights for improving trading performance.
