Introduction

The purpose of this document is to help clients get started with the EMS xAPI application on Python UI. This document provides a step-by-step process of installing Python on Windows and Linux and start using the APIs.

Eze EMS xAPI is robust and easy-to-use application that allows programmers and trading businesses to complete various trading workflows, and also access key information, including:

  • Automating order routing - to smart order routers, algorithms and other trading systems.
  • Routing orders to multiple brokers, dark pools, ATS, and MTFs via the Eze EMS Global Routing Network - across asset classes.
  • Staging or routing single or pairs orders.
  • Accessing balances, positions, executions, and other order details.
  • Accessing comprehensive list and basket capabilities.

Although EMS xAPI can operate with all gRPC compatible languages, only Python language information is provided in this document as an example. Refer to this link for more information on gRPC.

Eze EMS xAPI Basics

The Eze EMS xAPI operates in conjunction with your existing Eze EMS account permissioning and entitlements. The Eze EMS xAPI is not a standalone data feed application that is provided to you independent of the Eze EMS. Please contact Eze Client Service if you need to request or make changes to appropriate permissions for your account.
