What if we break 837 and go long? That's a big IF. What are some targets?
Here are some interesting fib clusters I've found in the 930's and 990-1000 areas (blue arrows). These areas also line up with past high pivots.
This is the ES daily chart...

Another way to look at it is to take a measurement of the last major move in the same direction. This gives the same projection to 930 and to 1000 (same as above).
However, this rally is looking a lot like the rally of July-August of 2008. If that is the case, we have already experienced the extended levels of that move.
