Since the 1990s, private traders can use the Internet to access the financial markets. Several trade platforms - the most popular is MetaTrader4™ (MT4) - offer automated trading functions. But they are mainly designed for manual trading and do not support research, development, and serious test of algorithmic strategies (see trading platform comparison). Consequently, private traders are normally not succesful with automated trading. And those who are normally don't use trading platforms, but mostly self-written software.
Zorro is the first free platform for research, exploring, developing, testing, and executing algorithmic strategies for trading stocks, forex, indices, ETFs, and other financial instruments on a serious level. It can run either as a stand-alone system with direct broker connection, or as an attachment to a trading platform (such as MetaTrader4) that is used for retrieving price quotes and sending commands 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:
- lite-C, easy script language with C syntax.
- Extremely simple: Strategies require only a few lines of script.
- True machine code compiler for fast backtests:
8 x faster than MQL4, 100 x faster than Python, 400 x faster than R.
- String, file, and vector/matrix function library.
- Event driven: Immediate reaction on price ticks.
- No limits: Full access to the Windows API and external DLLs.
- R bridge: Include R functions in trading, training and backtest.
