Order Flow
Order Flow: Transaction Request Routing
Order flow refers to the stream of buy and sell orders flowing through trading systems and how they're routed to different execution venues. It's like watching the flow of cars through different highway lanes to see which routes get the best traffic conditions.
Order flow encompasses the path that trading orders take from initial placement to final execution, including routing decisions that significantly affect execution quality and transaction costs. Understanding order flow reveals how trades are processed and who profits from transaction routing.
How Order Flow Works
Order routing algorithms analyze multiple execution venues to determine optimal transaction paths based on liquidity, fees, and execution speed.
Payment for order flow involves trading platforms receiving compensation from market makers for directing customer orders to specific execution venues.
MEV extraction occurs when sophisticated traders analyze predictable order flow patterns to profit from front-running or sandwich attacks.
