<r>Thank for your help. I only ask because I have been told that it wasn't worth trying to be cause it is unpredictable. I saw this piece on indexuniverse, it seems to discuss some of the returns behind these ETFs. <URL url="http://www.indexuniverse.com/publications/journalofindexes/joi-articles/641...

Can someone explain how a GAMMA Trade works or doesn't work with the leveraged ETFs? I have heard conflicting stories. Some say it is not predictable others say sure-- how do you set it up in a system, etc? Thanks for any guidance.
