As it can bee seen on the chart, OB- on 1H time frame was closed, and it went back down due to economic news and geopolitical issues.
However, the SPX recovered to fast from 3550's levels, and this was inevitable.
There are few FVG'g and OB+f that need to be filled before we can see recovery in the price.
Personally, I expect one bigger leg down, but here I'm trying to follow technicals. :)
Risky move!
Good luck!
