That model as described seems quite workable, albeit only 4 times per year on average. I am going to try a few tricks and see if I can increase the number of plays per year. But first I will attempt to develop similar models with some other sectors. I will try XAU and SOX. What other sectors can you think of that tend to move to their own beat, as opposed to following the major indices?? I can try RUT as well, although that is not technically a sector.
