I am looking for a broker who provides a free trading API for FX. The goal is to develop at-home algorithms in C# (possibly Qt) to run on a fake portfolio, and then later on real money with competitive broker fees.
Would you know some comparison of such APIs?
What do you think of OANDA? Dukascopy? TD Ameritrade?
Here is the list of APIs I have found so far:
- Delta Trading API
- Dukascopy bank trading API
- TD Ameritrade
