Put up an SPX 5 minute chart for the last two days. Look at the price action intraday. Whether the market is heading up or heading down, there are "waterfall" patterns all over the place. By waterfall, I mean some trend up/down, followed by some trend down/up, so that the pullbacks look like a movie of a ball bouncing within the trend [obviously on the way up, you have to turn the chart upside down since balls don't gain energy on each bounce.]
It is interesting and I wonder if anyone has ever done a study of it as to how it relates to market psychology.
