How the Public Dataset Is Tracked

rime runner example

This page explains exactly how alerts are measured, how structure is defined, and how results are documented in the public log.

One methodology
One dataset
No cherry-picking

The goal is consistency, transparency, and a rule-based record of scanner behavior.

15-Minute
All data is tracked on the 15-minute timeframe

9 EMA
Structure is defined by the 15-minute 9 EMA

First Alert Only
Only the first alert of each trading day is recorded

Nice Stock Scans records both winners and failures using the same rule set. The public log is designed to reflect scanner behavior consistently, not to maximize hindsight.

Scanner Data Methodology

01 Timeframe
All data is tracked using the 15-minute timeframe.

02 Structure Definition
Structure is defined by the 9 EMA on the 15-minute chart.

03 Measurement
Each alert is tracked from Alert Price → Structure Break Close.

04 Structure Break
A structure break occurs when a candle closes below the 9 EMA and the following candle confirms continuation below the line.

05 First Alert Rule
Only the first alert of each trading day is recorded in the dataset.

Edge Cases

Same-Candle High

If the alert and the high occur on the same 15-minute candle, the close of that candle is used.

Time Stamp Notes

Trade Ideas alerts can trigger mid-candle. This can create situations where the alert time and candle close appear out of order.

Example: Alert Time 9:55 / Structure Candle Close 9:45

To reduce confusion, the following candle close may be used for documentation.

Immediate Continuation

If a stock alerts and immediately trends higher within the same 15-minute window, the move is tracked until the first confirmed structure break close.

Alerts Below Structure

If a stock alerts below the 9 EMA but is riding continuation, the continuation is tracked until the next structure break close.

Fake Breakdown

If price closes once below the 9 EMA but immediately recovers and closes back above within 2 candles, the move is classified as a fake breakdown. The next true structure break close is used instead.

Riding the 9 EMA

If candles repeatedly wick below the 9 EMA but continue to close above it, the trend is considered intact. No structure break is recorded.

Conservative Tracking Rules

Nice Stock Scans intentionally tracks alerts conservatively.

  • Stocks that break structure before reigniting are recorded as failures
  • Over-extended pumps that later continue higher are still recorded at their first leg high.
  • Second alerts later in the day are not tracked

Only the first alert of the day is counted for data tracking purposes though the same stock can alert multiple times or multiple days.

Additional Notes

Multi-Day Moves
Multi-day runners are not tracked across days. A stock must re-qualify on the scanner the following day to generate a new alert.

After-Hours Data
Both pre-market and after-hours price action are included when evaluating structure.

Price Formatting
Sub-$1 securities may appear rounded in the platform. Alerts may occur to fractions of a penny, but prices are documented using the displayed platform value.

Accuracy Disclaimer

All data is tracked manually using the methodology described above.

Nice Stock Scans makes every effort to ensure the information is accurate and consistent, but minor discrepancies may occur due to:

  • alert timing within a candle
  • platform data differences
  • rounding on sub-$1 securities
  • manual data entry

All results are recorded to the best of our knowledge using the defined rule set.

Transparency

Nice Stock Scans records both winners and failures.

Every alert is documented using the same methodology.

No edits.

No deletions.

No cherry-picking.
