Yes, that's a key level for ES. If ES were to break above it on nice volume, then we could really have a big rally.
I am still VERY BEARISH right now. We'd need to break above the last few days highs for me to change bias.
PS: Although I am very bearish and got stopped out on one short, I did manage to catch a nice run with NQ on the way up. I am all flat now. Never trade your bias but what you see on the charts.
