HUGE Open interest on ES futures for nightitme

Something big is up, I normally see around 40 bid and ask around the trade price, but tonight saw often 1000 and even 3000. Something big is up,

I added shorts at 1112.5 on the ES. Sad after going short at 1103 that they ramped it up and I closed 70% of those shorts at a loss (but less than 1112, so I am back in short at a higher price.

Keep in mind the Euro swat down that I theorized has appeared to come true.
