This Forex Data API is an Application Programming Interface which helps you build custom applications using the Microsoft © .NET (dot NET) framework.
This API is provided free of charge to all ForexFeed.net clients. Please login to download this example and the .NET data API itself.
See the examples below (C# and VB) which make use of the .NET Forex Data Feed API to handle all the underlying logic. As you can see the API greatly simplifies many use cases.
Note: these are very simple examples of using the .NET Forex Data API. These examples illustrate how to retrieve data and print it to the standard System.Console.
