pdp,

thanks so much for sharing your work. this is very interesting, but i am surprised that you chose XLI as one of your 4 studies and UXI/SIJ as the trading vehicles within. the volume is so low on both of those ETFs that i wonder is it realistic to trade them? was there another runner up that had better volume in your tests, or were the results for the other candidates too poor?

i know you spent a tremendous amount of time on your studies, so thanks again for sharing it with the group,
lisa
