  • 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: CBOE moved up from $309.72 (the last daily swing) to $353.07, about 3.3 ATR, so the move is extended. Traders often watch the reversal first here.
  • Reversal check: a shooting star or bearish engulfing candle near $330.43.
  • Latest daily candle (Nov 5): Spinning Top (neutral).
  • Breakout check: RVOL above normal on the break (last day's RVOL: 1.2× on Nov 5).
  • Zone tests: price pushed above the zone top 1 time and fell back, and dipped below the bottom and recovered 4 times. Each test can weaken a zone.

Why mother bar matters

A mother bar is a big, high-volume bar that later bars stay inside. The volume shows big players were active, and the range they left becomes the box traders watch for the next move.

How traders use it

  • Wait for the first candle to close outside the mother bar, not just poke through it.
  • A close back inside after a breakout is a false breakout; many traders then watch the other side.
  • The longer price stays inside, the more energy traders expect for the breakout.

The last 10 mother bars

  • Of the last 10 daily mother bars, 10 had a close outside and 9 turned into false breakouts.
  • Latest 5-minute mother bar (Nov 6, 4:00 AM ET): $353.07 / $353.07, no breakout yet.
  • Gap: CBOE opened Nov 5 at $351.61, a gap up of 1.9% from $345.21; the gap was filled.
  • Round numbers nearby: $340.00, $350.00, $360.00.

Combined conditions

  • The daily zone is $300.50–$330.43. VWAP $351.27.
  • The delayed price is above the daily zone: watch for a retest or a false breakout.
