This is not a
But it can beat any.

Zorro is a free authoring tool for financial research and algorithmic trading systems - serious systems that really work. It offers advanced statistics, analysis, signal processing, pattern detection, and deep learning algorithms for analyzing the markets and determining the right moments to buy or sell.

Zorro provides many features otherwise not found in consumer trading software.
Strategy development with Visual Studio™
Easy or full-scale - your choice.

Start with the step-by-step programming tutorial. Zorro's C-based script offers a quick and elegant approach to strategy coding. It allows easy handling of time series, datasets, vectors, or matrix operations.

Write, test, and deploy simple strategies in a few minutes with a minimum of code. Use the included script editor and on-the-fly compiler for quick tasks. Or create your systems and tools with full-scale development platforms such as Microsoft Visual Studio™ with their advanced debugging and profiling features. It's your choice. Zorro accepts projects as scripts in C, or as compiled C++ DLLs.
Excel™-defined strategy control panel
Open architecture, fully customizable.

Zorro's user interface is admittedly minimalistic. But you can add your own. Design strategy control panels with an Excel™ spreadsheet, and define buttons, displays, sliders, entry fields, charts, and reports.

Automate routine tasks by running Zorro jobs from batch processes. Control web platforms by sending key strokes and mouse clicks. Implement new functions or new broker or feed connections with a simple DLL interface. Set up account and asset lists with any imaginable properties. Check your trading status online with individual HTML report pages. Import or export data in binary, CSV, or JSON formats for easy integration in other software packages.
'Butterfly' option combo analysis
A multitude of markets.

Analyze and trade portfolios of options, futures, stocks, bonds, ETFs, CFDs, Forex, or cryptocurrencies. Combine historical and live data from different online sources, feeds, brokers, or exchanges.

Create arbitrage strategies that exploit price differences between brokers or asset classes. Connect to coin exchanges and trade Bitcoin. Test high-frequency trading systems in 1-millisecond resolution. Rotate stock portfolios with Markowitz- or momentum-based algorithms. Trade option combos based on their Black-Scholes values, implied volatilities, or greeks.
White's Reality Check on a trend following system
Serious analysis and testing.

Evaluate market situations with a wide range of regression, signal analysis, filtering, or statistics functions. Or with neural networks from top-end packages such as Keras™ or Tensorflow™. Zorro can directly access all R-based data analysis, machine learning, and charting libraries.

Check your strategies with the world's fastest tick-level backtester (4 seconds for 10 years) or the step by step simulator. Verify results with Walk Forward Analysis, Montecarlo analysis, or White's Reality Check.

Market sentiment and order flow.

Amplify your trading algorithms by adding human intelligence. Feed Zorro with market sentiment data from a multitude of sources. Process option chains for detecting the market's opinion about the future price trend of the underlying. Define your own special bars - Renko, Range, Point-and-Figure, whatever - with a simple formula. Analyze candle patterns and price action with a self-learning algorithm. Evaluate order flow data with a neural net for retrieving short-term price predictions. Zorro provides easy to use indicator-like functions for all this and more.

Instant strategies.

Zorro includes several ready-to-run strategies for portfolios of Forex pairs, CFDs, stocks, ETFs, and cryptocurrencies. The Z strategies are based on published algorithms and cover a large range of markets, risks, win rates, and trading methods. They allow you to quickly experience a live trading system before developing your own strategies.

Still, always be aware that all trading strategies are risky, all backtest results are hypothetical, and never risk money that you can't afford to lose!
Why free?

For private traders, Zorro is available in a free version since its initial development was paid for. Our sponsor believed that all people, especially in developing countries, should understand the financial markets and participate in their profits. Small, but regular trading incomes for anyone can take liquidity out of the financial system and inject it back into the production cycle. This can boost demand worldwide, reduce the divide between rich and poor, and soften the world's economical and social problems.

In this way, Zorro is meant as an incentive to understand, analyze, experiment with, and exploit the financial markets with many different ideas and methods. Zorro's development is ongoing, meanwhile funded by the user community through sponsor licenses, strategy development contracts, and trading returns. New Zorro versions with new features come out every few months.
