77-81 is becoming critical support. If we blow through that I see March 13 and 17 lows coming into play, 39-46 in the next day or so. This afternoon's action has me thinking sooner than later.
Covering last short 86.25, a little support 83.75-86 may give a bounce. Will look to enter short again. As for 807...
This sequence works nicely,
