# Order Priority ⎊ Definition **Published:** 2026-03-12 **Author:** Greeks.live **Categories:** Definition --- ## Order Priority Order priority is the hierarchy established by an exchange to determine which orders get filled first. While FIFO is common, other systems exist, such as price-time, size-priority, or a combination of these. Understanding the priority rules is crucial for market makers who want to ensure their quotes are filled. If an exchange uses a pro-rata system, larger orders may receive a higher percentage of the trade volume. This can influence the strategies that participants use to gain an edge. Order priority ensures that the matching process remains orderly and follows the rules established by the exchange's governance. It is a fundamental component of market design that directly impacts participant behavior. - [Order Routing Privacy](https://term.greeks.live/definition/order-routing-privacy/) - [MEV and Frontrunning Risks](https://term.greeks.live/definition/mev-and-frontrunning-risks/) - [Matching Priority](https://term.greeks.live/definition/matching-priority/) - [Order Book Depth Bias](https://term.greeks.live/definition/order-book-depth-bias/) - [Exchange Governance](https://term.greeks.live/definition/exchange-governance/) - [Limit Order Book Imbalance](https://term.greeks.live/definition/limit-order-book-imbalance/) - [Recency Effect in Order Flow](https://term.greeks.live/definition/recency-effect-in-order-flow/) - [Iceberg Order](https://term.greeks.live/definition/iceberg-order/) ## Glossary ### [Order Cancellation Procedures](https://term.greeks.live/area/order-cancellation-procedures/) Action ⎊ Order cancellation procedures represent a critical component of trade lifecycle management, particularly within automated trading systems prevalent in cryptocurrency and derivatives markets. ### [Order Book Event Handling](https://term.greeks.live/area/order-book-event-handling/) Mechanism ⎊ Order book event handling functions as the core logic responsible for ingesting, validating, and applying granular state transitions within an exchange matching engine. ### [Liquidity Provision Incentives](https://term.greeks.live/area/liquidity-provision-incentives/) Incentive ⎊ Liquidity provision incentives represent a critical mechanism for bootstrapping decentralized exchange (DEX) functionality, offering rewards to users who deposit assets into liquidity pools. ### [Order Flow Analysis](https://term.greeks.live/area/order-flow-analysis/) Analysis ⎊ Order Flow Analysis, within cryptocurrency, options, and derivatives, represents the examination of aggregated buy and sell orders to gauge market participants’ intentions and potential price movements. ### [Trade Sequencing Logic](https://term.greeks.live/area/trade-sequencing-logic/) Algorithm ⎊ Trade sequencing logic, within cryptocurrency and derivatives markets, represents a pre-defined set of instructions governing the order of trade executions, designed to minimize market impact and optimize realized prices. ### [Order Management Systems](https://term.greeks.live/area/order-management-systems/) System ⎊ Order Management Systems (OMS) within cryptocurrency, options trading, and financial derivatives represent a critical infrastructure component facilitating the lifecycle of trades, from order origination to settlement. ### [Exchange Order Processing](https://term.greeks.live/area/exchange-order-processing/) Exchange ⎊ The core function of exchange order processing involves the automated matching of buy and sell orders across various asset classes, including cryptocurrencies, options, and financial derivatives. ### [Order Priority Standards](https://term.greeks.live/area/order-priority-standards/) Algorithm ⎊ Order priority standards within electronic exchanges represent the codified rules governing the sequencing of order execution when multiple orders arrive at the same price level. ### [Order Priority Compliance](https://term.greeks.live/area/order-priority-compliance/) Compliance ⎊ Order Priority Compliance, within cryptocurrency, options trading, and financial derivatives, represents the adherence to established protocols and regulatory frameworks governing the sequencing and execution of orders. ### [Limit Order Placement](https://term.greeks.live/area/limit-order-placement/) Order ⎊ A limit order placement represents a conditional instruction to execute a trade at a specified price or better. ## Discover More ### [Limit Order Protection](https://term.greeks.live/definition/limit-order-protection/) ![A multi-layered structure visually represents a structured financial product in decentralized finance DeFi.
