Today the first 1hr volume is almost at same level as first hour of 11/6, an clear indication instituions are selling.
After that, there is no big buyers coming to support the index and it keeps making lower lows, which basically means it is all day trader working on it
The volume picks up before the closing as many day traders close their short positions and call it a week.
We need to wait for institutions to come back and buy this up. Hopefully it is 492 but we wont know until we see it
