No reason not to. Markets do not just drop straight down from all time highs. Tops are made by numerous attempts to take out highs before the attempts finally fail.
Buy signals failing. Previous support of 2810 is now resistance. We need to trade above 2810 to get back in the long swing of things. I still have this one long trade going and will let it ride back up or stop out.
First we would need to trade above 2802 and establish that level, but 2810 is the big number. Make no mistake, we are still in an uptrend so I would expect at some point for these to be taken out. So far I have been premature with my "knife catching".
