Ok. A burning question thats been on my mind. Please help! I have been creating and designing "systems". Just simple rules, over three months data. Looking at different results, I will decide which one to trade. Some systems preform better then others - positive equity curve, and such (passes all by the book rules). But, there are some systems, which look absolutely horrible. They produce an equity curve that would wipe Bill Gates out in a month or two. So, you all know where I am going (if you read the header of the thread) why not reverse the signals of this system, and trade it from the other way? I am in the precept that there are strategy traders out there who pour over data and methods until they find the right one - is there a time that they just decide on the opposite of the worst one they have ever seen? This makes logical sense, and I am wondering if this is valid in any way, and worth persuing. Please help out. Thanks.
