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 8 gaps bigger than 0.3%, 4 filled the same day.
  • The average gap was 1.4%.
  • Round numbers nearby: $15.00, $20.00, $25.00.

Combined conditions

  • The delayed price is above the daily zone: watch for a retest or a false breakout.
