86.93 · bottom 25%middletop 25% · 91.98
  • Setups to watch: the zone broke to the upside. Watch for a retest of the zone top or a false breakout back inside.
  • Prior move: ERX moved down from $128.40 (the last daily swing) to $100.23, about 4.8 ATR, so the move is extended. Traders often watch the reversal first here.
  • Reversal check: a shooting star or bearish engulfing candle near $91.98.
  • Breakout check: RVOL above normal on the break (last day's RVOL: 1.1× on Nov 5).
  • Zone tests: price pushed above the zone top 0 times and fell back, and dipped below the bottom and recovered 0 times. Each test can weaken a zone.

Why opening range matters

The first minutes after the open carry the most volume and the overnight orders. The opening range shows where buyers and sellers first agreed, and a break out of it often sets the direction for the morning.

How traders use it

  • Opening range breakout (ORB): a close above the range high is read as a long signal, below the low as a short signal.
  • Many traders wait for RVOL above normal and a candle close outside the range, not just a poke.
  • A break that falls back inside the range is a failed breakout; the other side becomes the target.

What happened over the last 10 sessions

  • ERX closed the day above its 30-minute opening range on 1 of 10 days and below it on 4.
  • On Nov 5 the first close outside the 30-minute range came at 10:00 AM ET, above the range.
  • Gap: ERX opened Nov 5 at $107.81, a gap up of 2.1% from $105.58; the gap was filled.
  • Round numbers nearby: $90.00, $100.00, $110.00.

Combined conditions

  • VWAP ($105.18) was below the 30-minute range.
  • The delayed price is above the daily zone: watch for a retest or a false breakout.
