  • Setups to watch: the zone broke. Watch for a reclaim back into the zone (false breakdown) or a continuation lower.
  • Prior move: BTR moved down from $28.09 (the last daily swing) to $25.81, about 7.2 ATR, so the move is extended. Traders often watch the reversal first here.
  • Reversal check: a hammer or bullish engulfing candle near $26.09.
  • Breakout check: RVOL above normal on the break (last day's RVOL: 0.1× on Sep 23).
  • 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 gap matters

A gap shows news or orders that came in while the market was closed. Many traders watch whether price comes back to the prior close to "fill" the gap, or keeps running away from it.

How traders use it

  • Gap and go: a gap that holds above the premarket high (or below the low) often keeps running.
  • Gap fill: a gap that fades back toward the prior close; the fill level is the target traders watch.
  • Big gaps on news fill less often than small gaps on no news.

What happened over the last 10 days

  • Of the 7 gaps bigger than 0.3%, 0 filled the same day.
  • The average gap was 1.4%.
  • Round numbers nearby: $20.00, $25.00, $30.00.

Combined conditions

  • VWAP $25.35 is below the fill level.
  • The delayed price is below the daily zone: watch for a reclaim or a continuation lower.
