ES1!6013.25 tested our low 6k support in RTH yesterday and tested our key support around 5985-90 in premarket today and it held so far. I outlined both levels in yesterday's opening comments.

ES 1h showing the index broke down below a ST support line

A break below 5994 would take us to the 5981-5984 range, which is the last support level for the bulls. Beyond this, we may see 5945-50.
On the upside, a break above 6025-28 could extend the upside to 6035-37, followed by a massive resistance at 6055-60.
Due to the lower open, I expect some early morning upside. However, the rally will likely face resistance around 6025 or 35. We will likely see a downside reversal with a target just below the overnight low, at around 5985.
