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 8 turned into false breakouts.
  • Latest 5-minute mother bar (Nov 6, 7:15 AM ET): $25.23 / $25.11, no breakout yet.
  • Gap: AMSC opened Nov 5 at $26.59, a gap up of 1.3% from $26.26; the gap was filled.
  • Round numbers nearby: $20.00, $25.00, $30.00.

  • The daily zone is $24.87–$31.85. VWAP $24.33.
