monthly rolling...meaning it changes to update each day....so for the month...there, so far, is more selling of shares, than buying...tomorrow, take a look at the numbers again--if you see a narrower range between the two numbers, then you can deduce that people were buying today more than they were seling. If there is a wider range tomorrow, than, today, you can deduce that people were selling today....after watching it for a while, you can even figure out if the buying was an option play or a long play...all you do is compare is to the volume intraday..... Once I discovered this site...I have looked at it every single day--to find a pattern, if there is such a thing.
