Develop Your Own Application

CTS offers an open .NET API and an open FIX API which allow for third-party developers to develop their own applications
while using the scalability, speed, reliability, and robustness of CTS's back-end.

Easy to Use

T4 API simplifies development, saving time and frustration. CTS’s own T4 Desktop is written directly to T4 API, which allows for any functionality available on the T4 front ends to be duplicated on any other 3rd party application. Microsoft.NET permits applications to be written in languages such as advanced C++, C#, and Visual Basic, among others. Visual Studio 2005 and later is supported. The T4 API utilizes a single SSL connection, enabling easy passage through firewalls.
