Emg, if you want to be able to profit nicely from something that is trading within a range, if you want to avoid the big hit, stealing all the accumulated profits, when if finally takes off outside of that range, you definately need a stop.
here's one we used to do with grain spreads the pyramid is set up just like bowling pins 4,3,2,1 you always start off with 4 cars (or if you're big some multiple) add 3 to winner add 5 to loser etc. sometimes it works when it doesn't, it almost wipes you out (but not completely) you can save your ass by getting back to 4 cars when the profit and loss cross when it works you can make a lot of mistakes for a long time
