Market Microstructure: Order Types, Market Models, and Priority Rules
Summary
The article surveys market microstructure as the study of how trading rules and market design shape price formation, liquidity, and execution. It distinguishes quote-driven markets, where dealers or market makers provide quoted prices, from order-driven markets, where participant orders are matched under stated rules; hybrid arrangements can combine features. It also sketches broker and proprietary trading roles and gives examples of trading horizons, including high-frequency activity.
A substantial section classifies orders by price, time, quantity, or triggering condition, covering market, limit, stop, good-till-cancelled, immediate-or-cancel, day, disclosed-quantity, and conditional orders. It explains price, time, and size priority in order handling and briefly reviews momentum, mean-reversion, swing, day, technical, fundamental, and scalping styles. These are introductory definitions rather than a comparative analysis. The document does not provide empirical execution-cost estimates or assess how rules differ across venues, and some order behavior depends on exchange-specific rules.
Key ideas
- Market design and matching rules influence price formation, liquidity, and trading costs.
- Quote-driven markets rely on dealer quotes, while order-driven markets match participant orders under common rules.
- Orders can specify price, duration, quantity disclosure, or conditions for activation and execution.
- Price, time, and size are presented as possible order priority criteria.
- Trading styles such as momentum, mean reversion, and scalping reflect different ways traders seek returns.
