Automated Trading API's

Hi,

We are trying to use SterlingTrading API for automatic trading in our C#.NET application.

They support .NET 3.5 at this moment (no support for 4.0).

I am not sure if there are any other API's. I wanted to check if there are any other better alternatives for automated trading API's supporting C#.NET ?

Thanks.

 

If you are doing C#, check out tradelink:

Never used it, but QuickFIX claims to have a .NET wrapper, which may be useful if your broker allows you to connect via FIX:

interactivebrokers is one of the choices for .net / java / c++

 

Thank you all. I will look into the API's you mentioned.

 

dastrader.com offers a C# API, their limited api ($100/month) allows up to 50 orders/second

 

Yes, and - sorry - you would be quite stupid to use it, given that QuickFix has QUickFixN - which is a pure .NET implementation not using native code

 

MBTrading has an SDK. It's ActiveX so should be easy to use with C#. I think TradeLink has done the work for you as they support their SDK too.

 

I'm presently using CTS T4 for .net /C# /. I have used 2 prior , and this is the best API for my applications.

 

CQG Trader has an API version (from 25 usd pm)
also you may consider openquant for automated trading .
you just define strategies and connect to brokers via a multitude of connections
