Three things:
1) VIX exploding - close to 15 now !
2) The pattern of parabolic advance where subsequent corrections tend to be smaller in both duration and amplitude is broken.
3) Largest fastest decline since Aug 2017.
No wonder the board is mum today. Even the regular bullish noise is absent.
For the first time since Aug 2017, bears can try their luck on the short side. There was absolutely no reason to short since then. There is absolutely no reason not to, right now. I will wait for a retrace and go short either today or latest by tomorrow.
Good luck trading !
