Taz, I "Used" to look at that as well, but it's so behind as it can't tell the future. I saw all sells one day 100%, the next day the stock went up 18% by 9:45 am and the 10 day was at a buy and 20 at a hold.
In other words, you MISSED out on the jump. That chart basicly "reports" what happened but doesn't predict the future.
