Could be. I was going to mention the sell wiggles on some indices (3-straight daily doji's) the other day, but they have been kind of mixed in their results. It may have been only good for 1-day of down like the last time.
I was anticipating an intra-day low today at the lowest 2153 COMP. We exceeded that a bit. We'll see if that holds or this is the start of something bigger as you think.
