Wealth-Lab Developer is a stock and futures trading system development and back testing tool. It is a stock software program from Wealth-lab.com. A trading strategy (or, trading system) is a set of explicit rules that tell you when to buy, sell, sell short, and cover. It allows the trader to make his own trading strategies and see how they would have performed when he tries them out in real time, thus it is a kind of simulation. It also helps to explore the different systems contributed by the other members. The ranking of all trading systems is done on monthly basis to see which strategy is working best under tough market conditions. It is great for academic and research use.
