Today's 1-minute chart. You can see that there are a lot more large blocks that usual. Often I post the 5 minute chart but this shows individual trade size more clearly. Remember it's a dynamic chart, if you look at this on Thursday, today is the right-hand pane. If you look at it Friday, Thursday will be the left-hand pane.

It's real interesting to compare today's volume with yesterday's. THAT'S what shows how different today is from what has become the usual pattern.
