It appears most of the high end traders and hedge fund managers scoff at backtesting tools like Tradestation and Metastock. Most of them tend to favor Trading Recipes and Veritrader, anyone here on ET have any experience with them?
trading recipes covers far more scope. it isn't about testing "a" system, it is about testing a union of multiple systems. it can help you figure out how much to risk where, which is a far different question than "can i make money shorting a high RSI".
