What is FIX API

An API (Application Programming Interface) allows your app to communicate easily with different data sources. In other words, you can integrate an API into your app to fetch relevant data from various sources. This way, you don’t have to gather data from several sources by yourself, aggregate it, and display it on your app. Thus, APIs are widely used across industries, including the financial markets. For example, popular APIs, like Exchange Rates API or FIX API, use reliable data sources to provide accurate exchange rates. 

The FIX API Forex fosters a seamless flow of real-time data between market participants. It is widely used by liquidity providers, traders, and regulators. It allows you to address the market on an ongoing basis. But what is FIX API in Forex, and how is it helpful? This post will provide all the details.

High-Speed Connection

This means the API bypasses third-party platforms like MetaTrader 4. With this direct connectivity, traders typically see a low latency of around one millisecond. Thus, they can execute trades swiftly and quickly, which is crucial in fast-paced trading markets where every second matters.

Advanced Order Types

The API supports various order types. These include limit orders, market orders, stop orders, and more. This enables traders to implement advanced trading strategies and risk management techniques.

FIX API is widely accepted in the Forex trading community. Hence, you can concurrently connect with multiple brokers.  This way, you can monitor trading conditions like liquidity and spreads and identify potential trading opportunities across a wider array.

Scalability 

The FIX API is backed by a robust infrastructure that can handle high trading volumes smoothly and efficiently. This is especially beneficial for institutional traders and high-frequency trading (HFT) firms that execute large volumes of trades within short timeframes. 

Lightweight

The size of messages with FIX API is very small. Hence, you need to use minimal bandwidth to transmit them over the internet. The API also supports a high level of frequency. Thus, you can send messages hundreds of times per second.

What Type of Data does FIX API Facilitate?

What type of data do FIX API facilitate?

FIX API facilitates the transfer of three distinct types of data. Let’s take a look at them:

Pre-Trade

This type of data includes important information streaming directly from exchange or market servers. It includes levels of liquidity, order flow, and depth-of-market statistics. It is helpful in crafting trading strategies and decisions.

Trade

Trade-related data refers to the information conducting trade. There are a variety of functions that involve data transfer through FIX. It includes order entry, confirmation, and execution.

Post-Trade

What is the FIX Protocol?

FIX essentially stands for the Financial Information exchange. It is an open messaging standard. And it isn’t controlled by any single individual or entity. FIX protocol package enables you to communicate in real-time with clients, traders, brokers, and liquidity providers.

The idea for the FIX protocol was first developed in 1992. At that time, brokers were using phone trading for daily operations, like receiving and placing orders. However, the process was prone to error. Also, being manual, it was highly inefficient. The companies seamlessly transitioned from old-school analog trading practices to cutting-edge online trading thanks to the FIX API.

Initially, a few New York-based equities trading firms adopted the technology. The most notable companies were Fidelity Investments and Salomon Brothers. The latter was ultimately acquired by Citigroup.

The early version of FIX provided support for pre-trade and trade operations for equities markets.  However, technology has seen a major advancement throughout the years. Right now, the protocol supports the entire lifecycle of a financial transaction.

There are many versions of the FIX messaging protocol. The latest one is 5.0. However, 4.4 is the most widely applied version. It is massively popular among the Forex community.

Is FIX API Free?

Technically, the technology is free. However, this does not necessarily imply that you will have access to trade using FIX API from every Forex broker.

Because there is an administration cost, the broker has to deal with it. It leads to several requirements. For instance, brokers impose minimum deposit criteria. Also, they may impose minimum monthly trading volume criteria.

It is compatible with C++, C# and Java programming languages.
