Well, Gross says QE is the end of the bond rally, whether Wed or a month or two. I completely agree with Bill Gross when he says these problems are not Bernanke's but our own and it's sad it's come down to him to try and fix things. Just read this...
What I suspect is about to happen Wed is we get a pop, maybe even for a few days, then a BIG selloff. I say that only because everyone is talking a sell the news on the announcement. The "smart money" will clearly wait to do the math as for what it means. So the "real" market effect wont happen for awhile. As for daytrading it, you want to fade the move right after the announcement.
As for mini trading, I've learned to keep it simple. The 5 ema direction is what I use.
