What Is An Order Management System?

An Order Management System (OMS) is a digital system designed to efficiently and economically carry out securities orders. It is commonly employed by brokers and dealers to handle orders for different types of securities while keeping tabs on each order’s status within the system.

How Does An Order Management System Work?

To initiate the purchase or sale of a security, a dealer must submit a trade order comprising several crucial details:

  • The specific security involved is identified by its ticker symbol.
  • The order type, such as buy or sell.
  • The order’s size or quantity.
  • Additional instructions for the order.

Traditionally, dealers execute trade orders through order management software. Many order management system systems utilize the Financial Information exchange (FIX) protocol, which is prevalent in securities markets and facilitates a significant portion of transactions.

Furthermore, the order management platform maintains a comprehensive record of both active and completed orders, ensuring transparency for all parties involved in securities transactions.
