$ES - Key levels - will shorts be trapped??

Weird day today with NYSE VOLD up all day while NASDAQ VOLDQ down all day. Clearly shown by the big range indecision movements.

Key level to watch for a potentially huge bull run
- $4011 area, a breakout could trigger a significant bull run and catch shorts off-guard

Any thoughts?
