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

  • CATH closed the day above its 30-minute opening range on 3 of 10 days and below it on 3.
  • On Nov 5 the first close outside the 30-minute range came at 10:00 AM ET, below the range.
  • Gap: CATH opened Nov 5 at $91.10, a gap down of 0.3% from $91.35; the gap was not filled.
  • Round numbers nearby: $80.00, $85.00, $90.00.

Combined conditions

  • VWAP ($88.33) was below the 30-minute range.
  • The delayed price is at the middle of the daily zone: wait for an edge.

How to trade around CATH's opening range levels

1. 30-minute breakoutA 5-minute close above $91.24 after 10:00 AM with RVOL above normal is the breakout signal; back under $91.24 cancels it.
2. 30-minute breakdownA close under $89.81 with volume is the breakdown signal; a fast reclaim is a false breakdown.
