My original thoughts were that the Dax and Dow were going to suffer a lot more than the FTSE. The fact that the FTSE has rolled over first (I'm still assuming it has) will probably mean the decline in the UK market is less severe.
I'm happily day trading both the Dow and Dax and riding the up-moves along with the down. However, I do believe there's a lot of pain ahead for those two. I wouldn't like to say which of them will go first.
