I believe that the fact that we have so many pages in his thread so quickly is proof of the fact that many traders are still looking for that holy grail that will simply tell them when to trade without thinking each time. Markets are constantly changing and so automation will never be as successful as trading with your head first and the signals second. The only hard and fast rule that traders should keep that way is the limit on the amount of losses and that must be heavily influenced by percentage of total portfolio.
