Application Programming Interface (API)

An Application Programming Interface (API) is a way for a software programmer to communicate with an operating system or another program. Just as a graphical user interface (GUI) uses a window or a button to communicate with a user, an API uses a set of protocols and codes to communicate with an application or a program. In other words, an API is a piece of software code that acts as an intermediary between two electronic devices.

In financial markets, an API allows the exchange’s or broker’s platform to interact with various trading algorithms or models. It enables the automation of trading strategies by allowing the program to access the exchange’s data feeds and make buy-sell decisions. In order for a system to become automated, it needs to be programmed separately for each broker or platform. Therefore, the availability of API access is essential for executing automated trading strategies.

The API enables a broker to provide customers with a more sophisticated level of trading opportunities. For instance, customers can access customized market data, build algorithmic strategies for trading and receive real-time price feeds. Additionally, since an API does not require a user interface, fewer resources are needed to support the system, allowing customers more flexibility in the way they manage their trades.

Due to the potential associated with API trading, more brokers are now making their platforms available through an API. However, it is highly recommended that customers research all available options before deciding on a broker, as it is important they make sure the broker’s API offering meets all of their trading needs.

In conclusion, an API is an essential tool for implementing automated trading strategies and more brokers are making their platforms accessible through their APIs. It is important that customers research all available options before deciding on a broker, to ensure their API meets all of their specific trading needs.
