Definition

Smart Order Routing (SOR) is an automated process that evaluates available trading venues or liquidity sources and routes orders according to predefined execution rules. A router may consider price, available size, fees, speed, and other constraints.

How It Works

Orders are instructions, and their exact behavior depends on the conditions attached to them: price, quantity, timing, and what should happen if execution is only partly available. Before confirming an order, read the order type and validity fields rather than assuming every instruction behaves like a market order.

Why It Matters

This matters because two orders aimed at the same market can produce very different outcomes. Level 2 treats order mechanics as a safety skill: configure the instruction you actually intend, then review it before submission.

Key Takeaway

Smart Order Routing (SOR) is an automated process that evaluates available trading venues or liquidity sources and routes orders according to predefined execution rules.

Practical forex example

An order can trade on several venues. The SOR checks available prices and sends pieces of the order to venues that meet its execution logic rather than routing everything to one destination.

Why Smart Order Routing (SOR) matters

Understanding Smart Order Routing (SOR) helps traders interpret market information, plan decisions, and manage risk with more context.
