Ask HN: What are some good resources for learning about algorithmic trading?

I'm a developer interested in cryptocurrencies like everyone and recently stumbled upon what I think is the neatest exchange for purchasing and trading all sorts of digital monies (https://www.virwox.com/index.php).

They also have a trading API enabling bots, and it got me wondering if algorithmic trading strategies could be used on this smaller stage to learn something about the market, economics, and automated trading's possibilities (and pitfalls).

Does anyone have any resources for undertaking a project like this - using an API to pursue an automated trading strategy?
