...and what books should be read to learn enough to come out of the adventure wealthier (in knowledge, and finance) than he went into the experiment?

I have used interactivebrokers.com in the past. They have an API they make available (but you have to have their desktop client running). They are also a direct access broker so their fees are lower per trade ($1), their trades are routed more efficiently but they don't give you much tooling like the retail brokers.

Also, check out activequant.org. An open source project for high frequency trading. Several of the developers are either from Germany or German speaking. It's also pretty mature and has been actively maintained for at least 5+ years.
