What's the best API for automated forex trading? [closed]

Question

I am interested in writing a small automatic trader for the forex market. I would like to chose my own tools (platform and programming language) and I just need to find a decent API to query the numbers and that accepts requests for trading actions. I guess the ideal would be some web service with a XML API, or similar.

Any ideas?

Answer 1

Check out the InteractiveBrokers API or the Cunningham T4 API. Both are really good, although I'm not exactly sure T4 allows forex trading.

MT4 is the industry standard. It allows simple interface through .dll files and has an extensive support base.

except it's a desktop client, that won't work if you want to run an online system I suppose – Bondswoman

DLL files are compatible with .net so you can run them on a .net webserver. – Philia

There are a hundred ways to run it on/through a webserver. As I said, MT4 allows interface through dll files. That means you can interface with it through anything capable of interfacing with dll files (IIS, Apache, etc) . Additionally, you can use the Windows Desktop App API functions, (ex. msdn.microsoft.com/en-us/library/windows/desktop/…). Since you can run MT4 on Linux through Wine, this means that you can run it through a Linux-based webserver too. There are lots of other ways. Look up MT4-web bridge. – Brookner
