Thank You all. ER9, murray turtle, cluseau, vhehn, Capamunt, I really appreciate your feedback. vhehn, It really makes sense. I read in one post that he uses the Regular Big NASDAQ Contract to do analysis & take trade on mini contract. I did some research & found that to be helpful in that case. I do read books but I have yet to find where it discusses the pros & Cons of RTH & ETH. Greg
