I must admit, I am not smart enough to have devised these ridiculously simple Trading Rules. A great trader gave them to me some 15 years ago. However, I will tell you, they work. If you follow these rules, breaking them as infrequently as possible, you will make money year in and year out, some years better than others, some years worse - but you will make money. The rules are simple. Adherence to the rules is difficult.
If I've learned anything in my decades of trading, I've learned that the simple methods work best. Those who need to rely upon complex stochastics, linear weighted moving averages, smoothing techniques, Fibonacci numbers etc., usually find that they have so many things rolling around in their heads that they cannot make a rational decision. One technique says buy; another says sell. Another says sit tight while another says add to the trade. It sounds like a cliche, but simple methods work best.
