What is GeniusTrader?

GeniusTrader is a open source software suite to develop and test trading systems. A trading system is a set of rules that determines when to buy or sell a stock. This can be combined with moneymanagement rules, close-strategies and all the other stuff you may know from propietary systems. The decision to open or close a position depends on a Signal. A Signal is a simple boolean function. A signal (normally) indicates a situation in which it is reasonable that the value of the stock will rise or fall. Signals can be based on any kind of data (e.g. a candlestick pattern) but they are mostly based on an indicator. An Indicator is calculated on the values of the stock. It can be a simple moving average or a complex formula covering several sheets of paper. All these informations can be displayed graphically using the script graphic.pl. More important than a nice picture is the performance of the system. The performance and many other factors that are useful for the evaluation of a system can be calculated using the backtest.pl-script. All these features are available from the commandline - but we plan to build a webinterface for the future. The great advantage of the commandline is that the extensive perl-features of code-evaluation at runtime are used so that it is easy to build complex systems at the commandline.
