Execution Logic
Execution logic refers to the set of rules and algorithms that govern how an order is filled. This includes the priority rules of the matching engine, such as price-time priority, where the best price is filled first, and if prices are equal, the order that arrived first is filled.
In the context of algorithmic trading, execution logic also includes strategies like iceberg orders, which hide the true size of a large trade, or time-weighted average price strategies that break up large orders over time. These strategies are designed to minimize market impact and ensure the best possible execution price.
For developers, designing effective execution logic is essential for creating competitive and user-friendly trading platforms. It determines the efficiency and fairness of the trading process.
It is a critical aspect of how markets function in practice.
