Online Brokerage With API?

palpatine asks: "I'm looking around for an Internet brokerage that offers a programming interface. Instead of using the Web and forms to make and track orders, I'd like to be able to have some sort of library with functions for making and tracking orders as well as getting real-time quotes, securely over the Internet. Does anyone know of such a place?" Is there such a beast?

    - There's really no difference between an API and
    a web user-interface, except stability.

    - Making a screen-scraper is a piss-poor OSS
    project, because it would be broken most of the
    time because of (1).

    - .NET is only projected to get a maximum of 40%
    penetration. The rest of the WebServices market
    will be pure SOAP, mostly Java-backed.

    If a brokerage made me an API, they'd get my
    business in a flash.

    Never traded with them. I trade through TerraNovaOnline.com. A realtick based brokerage (they also have some java thing). A previous poster mentioned RealTick as scriptable, but I have not tried this..

    And if you are serious about trading, get a brokerage that allows trades through ARCA. This will allow you to place orders with trailing stops. Very handy.
