Many brokers and exchanges can nowadays be accessed online with a REST API that communicates with plain-text HTTP requests. The days of awkward proprietary broker APIs are coming to an end. This article is a step by step instruction of implementating a REST API interface in C for connecting a trading system to the Bittrex cryptocurrency exchange. It’s for the Zorro platform, but the principles are also valid for other exchanges and platforms. The C code for a basic REST API implementation is relatively short and straightforward.

Dear Brokers…
Whatever software we’re using for automated trading: We all need some broker connection for the algorithm to receive price quotes and place trades. Seemingly a simple task. And almost any broker supports it through a protocol such as FIX, through an automated platform such as MT4™, or through a specific broker API. But if you think you can quickly hook up your trading software to a broker API, you’re up for a bad surprise. Dear brokers – please read this post and try to make hacker’s and coder’s lifes a little easier! Continue reading “Dear Brokers…”
I Hired a Contract Coder
You’re a trader with serious ambitions to use algorithmic methods. You already have an idea to be converted to an algorithm. The problem: You do not know to read or write code. So you hire a contract coder. A guy who’s paid for delivering a script that you can drop in your MT4, Ninja, TradeStation, or Zorro platform. Congratulations, now you’re an algorithmic trader. Just start the script and wait for the money to roll in. – Does this really work? Answer: it depends. Continue reading “I Hired a Contract Coder”
Hacker’s Tools
For our financial hacking experiments (and for harvesting their financial fruits) we need some software machinery for research, testing, training, and live trading financial algorithms. There are many tools for algo trading, but no existing software platform today is really up to all those tasks. You have to put together your system from different software packages. Fortunately, two are normally sufficient. I’ll use Zorro and R for most articles on this blog, but will also occasionally look into other tools. Continue reading “Hacker’s Tools”
Money and How to Get It
Contrary to popular belief, money is no material good. It is created out of nothing by banks lending it. Therefore, for each newly created lot of money there’s the same amount of debt. You’re destroying the money by repaying your credits. Since this requires a higher sum due to interest and compound interest, and since money is also permanently withdrawn from circulation by hoarding, the entire money supply must constantly grow. It must never shrink. If it still does, as in the 1930 economic crisis, loan defaults, bank crashes and bankruptcies are the result. The monetary system is therefore a classic Ponzi scheme.
