I trade a manual system that i develop on my own thru trial and error. And I do not know if I can explain how I really do it. It just works for me.
My suggetion is to work at it till you get it on your own. I had many systems from others that i end up giving away to this forum, because I never felt confortable trading them. I still keep an open mind and I love this forum sharing spirit. I hope this helps.
