I must concur...great post. Although I've never paid money outright for a system, I have incorporated many trading ideas into my own trading from various books and trading magazines over the years. What have I learned? The same thing as you learned...the system has to make sense to YOU, the trader. And, like you, I've also learned the hard way that simpler usually IS better. You really can take an old idea, put your own twist on it, and make money if you are dedicated and consistant in your execution.
