In the past, trading involved connecting with brokers over the telephone to receive financial advice and make investment decisions. However, technological advancements have streamlined the process, reducing human intervention. Nowadays, trading platforms rely on APIs and software to perform functions and execute market orders.

Automating the trading process enhances the overall trading experience, leading to more efficient markets. Additionally, Forex brokerage firms can onboard more clients with ease. Now, let’s delve into the significance of FIX API in trading platforms and how it operates.

How Are APIs Used?

APIs, or application programming interfaces, are a set of protocols that enable communication and data exchange between servers and platforms. These programs utilise predefined commands and workflows, which are activated automatically once specific conditions are met.

Any service or application can use APIs, including the weather application on your mobile device or a newsfeed that receives and disseminates information and updates from the source in a timely manner to your device.

How Does FIX API Work?

APIs have a significant role in trading platforms, as they connect different servers, receive information from various sources, and communicate it to the client’s trader’s room. 

For instance, APIs connect the trading platform with multiple financial market servers to broadcast price updates and market changes. This helps the trader create their trading strategy and promptly respond to updates and price action.

Most Forex brokerage companies opt for FIX API for its convenience and well-structured data representation. This feature makes it one of the quickest protocols for exchanging data. FIX APIs are compatible with sophisticated trading platforms offering automated and copy trading capabilities.

Benefits and Drawbacks of Implementing FIX APIs

Trading platforms and other service providers can benefit from FIX APIs, but there are advantages and drawbacks to their use.


  • FIX API facilitates fast data exchange with minimal input and bandwidth, enabling traders to make faster trading decisions.
  • FIX APIs facilitate communication and data representation across multiple programming languages.
  • Data representation in FIX protocols is better organised and more accessible for interaction.
  • FIX protocols can execute market orders for various assets, including Forex, stocks, bonds, and cryptocurrencies.


  • FIX APIs can only transmit live market information and cannot be used for historical data visualisation.
  • FIX APIs only allow limited data exchange. Account balance, equity, and pending orders are not included.


FIX API is a commonly used protocol that enables real-time data exchange with financial markets. It allows traders to communicate with Forex, stocks, bonds, and crypto markets using different programming languages and request a large volume of data without depending on the trading platform.
