Introduction

Order Management Service (OMS) REST API serves two main functions:

  1. Facilitating the buying/selling of financial instruments traded in the market.
  2. Managing the cancellation of trade orders for the financial instruments.

To trade using the OMS API, it is essential to understand the flows and details of the following processes:

  • Order lifecycle in trading,
  • Placing an order (order creation),
  • Canceling an order before there is a deal (order execution) on the market,
  • Notifications about an order.

These flows and processes will be presented in the following sections.

Before delving into the flows and processes, it is recommended that you read the Concepts section from the OMS API perspective.
