I've learned a lot from Chuck Le Beau's website at www.traderclub.com as I myself am a fairly mechanical trader. In the site, he has a simple long-only stock trading system which seems to backtest well during weak markets (http://traderclub.com/discus/messages/107/1571.html?FridayNovember220011107am). Has anyone here tried his system lately? It's a free system, by the way. The rules are on the link above.
