# Introduction

FIX (Financial Information eXchange) is an open, industry-standard protocol for the electronic transmission of orders and related data. The protocol is defined and maintained by an industry association, the [FIX Trading Community](https://www.fixtrading.org).

Use of FIX requires an integration process lead by our FIX Engineering team, who can be reached at [fixengineering@ibkr.com](mailto:fixengineering@ibkr.com).
