I think I can describe what goes on over at Bright better then Don can. LOL. What I think Don is trying to say is, in order to get overnight leverage, you need to hold a book of positions that are dollar neutral to spread out the risk. So the GE/SPY example is poor. Ideally you would be long say 20 different stocks and short the SPY against them so what happened in SHLD doesn't blow out your account. Don should have explained it this way. So hopefully that clears things up. Don, if you have any more questions about Bright Trading, I'll be happy to answer them!
