1620 Demand zone broken with force

Today, the demand zone that I have had on my 100K vol chart for a month was broken with some force. Next stop is the demand zone at 1590 - 1595, however, it may not get there tomorrow. The reason for this is that I saw large volume at the close on the last two bars on the 1 minute chart.

So this may signal a bit of a fight back, but probably just back up to the 1620 level which is now a throwback zone.  We will probably hit 1600 before the retrace back to 1620.

Once we had broken the demand zone, we had several very good selling opportunities at supply or throwback zones. There were a couple of largish retraces of about 8 points each. But on a day like today, it was best sticking to short trades only.

If I am right, and we do get to the next demand level, then it represents a very good buying opportunity, as price will have dropped nearly 100 points and shaken out the market. 

As the USA employment data is coming out over the next 2 days, culminating with the NFP on Friday, we could just get the push down where the Smart Money will be waiting to buy from weak holders.  The next 2 days will be very interesting indeed.

Here are some charts:
