Maybe they were not my cup of tea because I day trade. I like the system that I use. Works well......
I've used the basic Ptibull method. Since it gloms off of IBD's CANSLIM method, it only works in early bull markets. I looked at their shorting method and it was too much record keeping for me, and looked like it would only work in an early bear market.
If you read the thread on keeping it simple that is really the way to trade. I trade only SPY or ES. Use 4 indicators MA, BB, Stoch, volitility. One heavily, the MA. And try to relax. And keep my trading down to a roar.
