Gap & Base Breakout Screener
Finds stocks that gap up, go quiet in a tight sideways base, then break out of the top of that base on a wide-range bar. Built for the Pine Screener, and it also draws the setup on your chart.
How it works
Why the high and not the close: on the chart, MSFT's Sep 25, 2026 bar cleared its 38-day base intraday (high 519.40 vs base high 517.77) but closed at 516.17, just inside. A close-only trigger misses day one of the move. The strong-close filter keeps wicky fakeouts out.
How to use it (Pine Screener)
Settings: change the range width (for example 5% or 2%) with the gear icon. For tight widths, raise "Max bars from gap to base start" to about 40, because tight ranges usually form late in a longer consolidation.
Columns: Breakout (1/0), In Base (1/0), Base Days, Base Width %, Bars Since Gap, Gap %, Distance to Base High %, Bar Range x Average, Relative Volume, 20-day Dollar Volume ($M).
On the chart: the yellow box is the current base, labeled with its length and width. The green label marks the gap. The triangle marks the breakout bar. Two alerts: Gap Base Breakout and Gap Base Setup.
What makes it different: instead of measuring a fixed lookback, it searches for the longest base that fits your width, ties that base to a specific gap-up, and requires the base to hold the gap. The result is post-gap consolidations, not random tight ranges.
Limitations
How it works
- Gap: an open at least 4% above the prior close, on 1.5x the 50-day average volume.
- Base: the longest stretch of 5+ bars whose high-to-low range stays within your max width (default 10%). It must start within 10 bars of the gap and hold above the pre-gap close.
- Breakout: the high clears the base high, the bar closes in the top 30% of its range, the range is at least 1.5x the 20-day average, and volume is at least average.

How to use it (Pine Screener)
- Add the script to Favorites, open the Pine Screener and pick an index or watchlist.
- Add indicator, select this script and set the timeframe to 1D.
- Filter "1 Breakout" above 0.5 for today's breakouts, or "2 In Base" above 0.5 for stocks still basing.
- Click Scan. For In Base, sort "7 Dist To Base High pct" ascending: the names closest to the lid come first.
Settings: change the range width (for example 5% or 2%) with the gear icon. For tight widths, raise "Max bars from gap to base start" to about 40, because tight ranges usually form late in a longer consolidation.

Limitations
- Cash buyouts gap up and then pin flat near the deal price, which looks like a base. A minimum 5-day average daily range (default 0.75%) removes most of them. Check the news on anything under about 3% wide.
- It cannot tell whether the gap came from a real earnings beat. Check the catalyst yourself.
- Pine Screener calculates on the last 500 bars. The base search looks back up to 120 bars by default.
- A setup is not a guarantee. Many bases fail or break down instead.
