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?

Are you fucking nuts?

[Profane Motherfucker]

My god man, are you absofuckinglutely positive that is what you want? You want unfuckingfettered access, secure, online, with an API? And for you personally? Can you be a little more fucking unrealistic?

Here's the fucking low down: you are asking for the ability to create your own person, on fucking line brokerage by hijacking another on fucking line brokerage. Straight fucking shit. You are asking for the ability to use a company's product in a manner that is totally fucking at odds with their ability to do this. To wit: Not fucking gonna happen.

No cocksucker worth his salt is going to let this shit fly, and the fucking slashdot audience is probably as far from the fucking authorita you want.

But hey, I could be a total ass rag about this. Look, my fucking four fucking letter word rant ain't fucking flamebait. I'm not going to jerk you off and pat you on the back. I'm giving it to you right on the motherfucking level.

Wow, your intelligence is matched only by your couth. Great just what we need the Eddie Murphy of slashdot.

I take it you've never heard of using an API which supports authentication? Start an secure connection, here's my name, here's my password, ok well here's a token good only for this session now communicate to me using this token over the secure connection. Duh.

Island, Redibook

I know that Redibook and Island have Windows API's available for directly connecting to their networks.

The big question, though, is how much trading volume you do. To support that type of direct access to an ECN, you need an account with a clearing firm; and they probably have steep account minimums and capital requirements. I doubt if there is anything out there that will let you just open an account for $50,000 and place orders with your own programs. In short, sure it's possible, but it would probably be uneconomical unless you are running a full-time trading operation.

Where I used to work, Townsend Analytics we have a product called RealTick, which (if you pay for it) does come with its own API you can use to alter the software and bend it to your needs. Its made for serious daytraders though, so unless you have the desire to trade and the money for the account don't bother. We tend to be "cutting edge" with online trading, I.E. our software is usually a little buggy, but it will always have the newest features. In fact it's considered the Coca-Cola of the trading industry, being one of the most widly recognized names. Give it a look see. And if you do call up and order, tell em Chucakles said go to hell. They know who I am ;)

Google me this...

Lime Brokerage provides a system that provides what you are looking for. They even use all of the keywords you mention (Internet, security, api, programmable).

There Brokerage Service, however, seems to be geared more towards Order Placement through an ECN. Here are some screen shots of the GUI that is provided with the API.

nasdaq.com XML interface

You can url encode stock symbols and get back XML from nasdaq via something like

ya, there's a cut&paste space in the url. I saw it after I posted, but I figured that it was pretty obvious :)

A few options

On non-windows platforms you're pretty much limited to MyTrack Java SDK and Interactive Brokers (Doesn't play nice with mozilla) for retail services.

MyTrack offers pretty good data although it can lag a good bit behind the marked (5-20 sec) and seems to be mostly unsupported.

IB's data is, well, you wouldn't want to trade off it alone. However the executions are great and their fee schedule is very competitive. Their Java TWS, which runs very well on Linux/UNIX, is somewhat programmable via either a socket interface or Java API.

I haven't worked with the MyTrack SDK for years so I can't comment on MyTrack's performance recently, but their executions were not comparable with other EDAT brokers and barely up to web broker standards when I used them. IB offers pretty good market coverage especially in commodities and options. Currently their API limits executions to their proprietary routing system, the client offers direct access routing to various exchanges. They also offer a much richer API to pro customers although their fees aren't as competitive in that area.

It's also worth mentioning that IB's platform is a bare-bones, no handholding, execution platform. If you want support and fancy tools go elsewhere but their executions and margin policies are pretty good (exchange min. on most contracts). When there is a problem however, you'll be happy to have a backup broker to hedge the positions you hold with IB. They require this in their customer agreement

See ibusers Yahoo group and EliteTrader Direct Access forum for more information. I only mention options that are available on Linux/UNIX for retail brokers because thats all I've investigated for my own use. I may post a better summary when I recover from last night..
