He needs to get in touch with the stock exchange (and brokers) before jumping into any implementation conclusions. He is not a broker, you can't really interact with any exchange directly. He needs to use some bank (which will already do 99% of what he is implementing). Without knowing exactly how the market systems work, this is a toy, he should have talked to someone BEFORE writing any code. Things are way more complex and simpler than it looks. It's extremely simple to use bank services to do that for you and close to impossible for a developer to just jumpt into writing trading software without a bank backing it.

Considering that users in this thread might be interested in trading software, let me add this link I posted yesterday: http://news.ycombinator.com/item?id=5041040 http://news.ycombinator.com/item?id=5041040 "Markets too complex for high frequency trading software"

Someone ought to create a "stripe for stock trades" to make building stock bots easy-peasy for any developer looking for a challenge. I'd certainly use it.

  Sounds like an idea PG would fund. The problem here is not even money, is having enough influence to get people and banks to trust you - and get a deal sweet enough to be profitable.

    And that's exactly why is not that easy to get in touch with banks and brokers too. "Financials" sucks and they hide every inner workings...

This isn't quite accurate. There are brokerages such as Interactive Brokers that provide an API so that you can write automated trading systems. And automated trading isn't limited to just high frequency trading. It's true that most banks have the simple features he mentions in the post but as soon as you want to get a bit more complex what the bank offers just isn't going to cut it.

  Yes indeed. The problem with using smaller brokerages would be the pricing (because he is trying to be some kind of broker himself). Banks (investment banks) can even expose the exchange 'API' directly to you. EBS kind of does that for FX
