How to Use GapUpTracker
Everything you need to detect post-earnings gap-ups, read the Rerate Score, identify entry setups, and track outcomes — from first scan to final exit.
Getting Started
GapUpTracker runs two automated scans every trading day — a pre-market detection sweep at 14:00 GMT+2 and a post-close outcome update at 22:15 GMT+2. You don't need to do anything to trigger these; just visit the Dashboard to see today's results.
Open the Dashboard
See today's detected gap-ups ranked by Rerate Score, volume significance, and setup type.
Read the Score
Each stock gets a 0–100 composite Rerate Score from 8 fundamental dimensions.
Check the Setup
The system auto-classifies each gap into one of four technical entry setups.
Dashboard
The Dashboard is your daily command center. It shows today's gap-up detections alongside the past week's results, with summary stats at the top.
Today's Detections
Every gap-up >5% detected by the morning scan, sorted by gap magnitude. Each row shows the ticker, gap %, volume significance badge, Rerate Score, and auto-classified entry setup.
Summary Stats
Total gap-ups tracked, today's count, average Rerate Score, and how many hit "Highly Significant" volume.
Manual Ticker Analysis
Use the "Analyze a Ticker" field to add any stock symbol. The system fetches price data, detects gaps, runs the full rerating analysis, and adds it to the tracker.
Recent Gap-Ups
A rolling view of the past week's detections so you can follow what happened after earlier signals.
Screener
The Screener lets you filter all historical gap-ups by multiple criteria to find exactly the setups you're looking for.
| Filter | What it does |
|---|---|
| Min Gap % | Only show gaps above a threshold (e.g., >5%, >10%) |
| Min Rerate Score | Filter to high-conviction names (e.g., ≥50 or ≥75) |
| Volume Significance | Show only Significant or Highly Significant volume gaps |
| Setup Type | Filter by Day-1 Play, Consolidation, 10-EMA Pullback, or Failed Gap |
| Date Range | Narrow to a specific earnings season or time window |
EPS Calendar
The EPS Calendar shows upcoming earnings reports so you know which stocks are reporting soon and might produce gap-up signals. The calendar refreshes weekly (Sundays at 20:00 GMT+2) and covers the next several weeks of reports.
Tip: Check the calendar on Sunday evening to plan your week. Stocks reporting the next morning will appear in the pre-market scan if they gap up — but knowing the schedule ahead of time lets you pre-position watchlists.
Historical Tracker
The Historical Tracker is the accountability engine. For every detected gap-up, forward returns are recorded at 1-day, 5-day, 20-day, and 60-day horizons — along with max gain and max drawdown. This lets you audit whether the Rerate Score actually predicts outcomes.
Score Buckets
Gap-ups are grouped into score ranges (0–25, 25–50, 50–75, 75–100) with average forward returns for each bucket. See which score levels actually deliver.
Self-Learning A/B
A backtested comparison of immediate zone entry (Entry 1) vs. confirmation-filtered entry (Entry 2). Entry 1 won with Sharpe 2.87 and PF 2.02 across 252 trades.
Understanding the Rerate Score
The Rerate Score is a composite 0–100 rating that measures the probability of a sustained Wall Street reprice. It's built from 8 weighted dimensions, each scored by the GLM analyst after reading the earnings report.
Strong multi-dimensional rerating thesis. Multiple catalysts aligning.
Solid rerating signals with some gaps. Worth tracking for confirmation.
Limited fundamental catalysts. Price action may be noise-driven.
Minimal rerating evidence. High probability of gap failure.
Technical Entry Setups
Every detected gap-up is auto-classified into one of four setups. Each has a specific entry trigger and stop level. The system uses the Entry 1 strategy (immediate zone entry) as validated by the self-learning backtest.
Day-1 Play
Entry: Enter near the close on the gap day, or on a breakout above the opening-range high (first 30–60 min). Close must be at or above the open.
Stop: Gap-day low. If price breaks below the low of the gap candle, the institutional bid is gone.
Consolidation Entry
Entry: Buy on a daily close above the consolidation range high. Require a confirmed close with above-average volume.
Stop: Consolidation range low, or the gap-day low if the range low is higher.
10-EMA Pullback
Entry: Buy when price pulls back to within 1.5% of the 10-EMA and then reclaims it (closes above) on rising volume.
Stop: Gap-day low. If that breaks during the pullback, the setup converts to a Failed Gap.
Failed Gap
Entry: No new long entries. Exit existing positions immediately. Aggressive traders may short with a stop at the gap-day high.
Stop: For shorts: gap-day high. The gap has failed — respect the signal.
Manual Ticker Analysis
Want to analyze a specific stock? Use the “Analyze a Ticker” input on the Dashboard. Enter any stock symbol and the system will:
- 1Fetch recent price history via the yfinance data sidecar
- 2Detect any gap-ups >5% in the lookback window (auto-detect or date-specific)
- 3Run the full 8-dimension Rerate Score analysis via the GLM analyst
- 4Classify the technical entry setup
- 5Add the stock to your tracked list for ongoing outcome monitoring
Scanning Schedule
GapUpTracker runs on autopilot. Three cron jobs keep the data fresh:
| Time (GMT+2) | Job | What happens |
|---|---|---|
| 14:00 | Pre-Market Scan | Detects new gap-ups >5% from pre-market/earnings data. 1.5 hours before NYSE open at 15:30 local. |
| 22:15 | Post-Close Update | Records forward returns, checks for failed gaps (broke gap-day low), updates outcome tracking. 15 min after close. |
| Sun 20:00 | Earnings Calendar | Refreshes the upcoming earnings calendar for the next several weeks. |
Frequently Asked Questions
What counts as a gap-up?
Any stock that opens more than 5% above its previous day's close following an earnings report. The 5% threshold filters out noise — below that level, the signal-to-noise ratio is too low for institutional rerating detection.
What is "Volume Significance"?
Session volume is compared to the stock's 50-day average volume. A ratio of ≥0.4× is flagged as Significant; ≥1.0× (i.e., double the average) is Highly Significant — the fingerprint of institutional accumulation driving the gap.
How is the Rerate Score calculated?
A Z.AI GLM analyst reads the earnings report across 8 weighted dimensions (Products 15%, Market Opportunity 15%, Valuation 15%, FCF Trajectory 15%, Partnerships 10%, Buybacks 10%, Guidance 10%, Earnings Beat 10%) and collapses them into a composite 0–100 score. When no API key is configured, a transparent heuristic model derives a score from EPS surprise, guidance, gap magnitude, volume, and Stage-reversal signals.
What score should I look for?
Scores of 50+ indicate a moderate-to-strong rerating thesis. Scores of 75+ are high-conviction. However, always cross-reference the Rerate Score with the technical setup and volume significance before entering a trade.
How often is the data updated?
Pre-market scans run at 14:00 GMT+2 (1.5 hours before NYSE open). Post-close outcome updates run at 22:15 GMT+2 (15 minutes after close). Earnings calendar refreshes weekly on Sundays at 20:00 GMT+2.
Can I analyze any ticker manually?
Yes. On the Dashboard, use the "Analyze a Ticker" input to add any stock symbol. The system will fetch price data, detect recent gap-ups, run the full rerating analysis, and add it to your tracked list.
