Since the 1990s, private traders can use the Internet to access the financial markets. Several trade platforms offer automated trading functions. But they are mainly designed for manual trading and not well suited for developing and testing algorithmic strategies (see trading platform comparison). Consequently, private traders are normally not succesful with automated trading. Those who are
normally don't use trading platforms, but self-written software.
Zorro is a free tool for executing financial algorithms. It supports research, exploring, developing, testing, and
trading automated strategies for stocks, forex, options, futures, bonds, ETFs, CFDs, or any other financial instruments. It can run
either as a stand-alone system with direct broker/market connection, or as an attachment to a trading platform (such as MT4 by Metaquotes™ or TWS by Interactive Brokers™) that is used for
connecting to the broker.
Converting a trade idea into an automated trade system, testing and trading it is a lot easier and faster with Zorro than with conventional platforms. Here's a tiny video course about developing a simple daily trade system:
- C based compiled script language.
- String, file, and vector/matrix functions.
