Order execution and API for web

I am looking for a broker which provides API for their web based trading platform so I can execute my buy and sell orders automatically using my code. Is there any broker exist out there to use?

 

IB

 

I think cqg has a web API

 

TradeStation has Web API also

 

Thank you. The problem with tradestation is that you have to open an account and fund with real money first then use the API which is nonsense. I'm trying to test something. I'm looking into cqg. Seems solid

 

Seconding Interactive Brokers.

 

CQG is a lot of work and not cheap. TradeStation's web api is very simple and I don't think you need much to fund it.
IB's Web API is good but I doubt it allows you to trade, it's data only.

 

A lot of ET posters from the developing world have <$100 of risk capital.

 

Had no idea US is among those countries! Good to know! Thanks gasp, I will try tradesration again

 

Then I'd say those guys are pretty screwed
