New ON
A condition matters when it changes from OFF to ON on the latest trading day. Continuing signals are weaker than fresh triggers.
How JOO LAB reads US signal conditions.
The main signal is not a market-index widget. The core is stock-level new-on detection, signal clustering, volume confirmation, and D+ performance tracking.
Cluster
One signal is a clue. Multiple categories firing together are stronger because trend, momentum, volume, and accumulation confirm each other.
Volume
RVOL 1.5x, RVOL 2.0x, trading value above the 20-day average, or trading value 2x are treated as confirmation layers.
D+ Review
Signals are reviewed from D+1 through D+7, with D+10 and D+20 reserved for longer performance history.
Weight System
Signal strength is ranked by weight and confirmation.
| Score Layer | Number / Threshold | Meaning |
|---|---|---|
| Core signal count | 2+ is stronger than 1 | Multiple core triggers reduce single-indicator noise. |
| Category count | 3+ categories | Trend + momentum + volume/accumulation is preferred. |
| Weight sum | 30+ strong, 50+ high cluster | Composite and volume-backed signals carry higher weight. |
| Trading value | $1M minimum scan floor | Low-liquidity names are filtered out at the data layer. |
| Overheat filter | Recent 5-day return above normal range is avoided | Signals after excessive short-term moves are discounted. |
| Performance window | D+1~D+7, D+10, D+20 | Short-term review plus final 20-trading-day history. |

Key numeric levels
30 and 40 are recovery zones. 50 is trend confirmation. 60 is stronger momentum continuation.
MACD cross is early. Zero-line is stronger. Histogram positive turn is acceleration.
Used to avoid late overbought crosses.
-100 recovery detects rebound; 0-line suggests stronger momentum recovery.
Volume-weighted momentum. 50 breakout is a stronger money-flow signal.
Above 0 means accumulation pressure. Above 0.1 is a stronger accumulation reading.
1.5x confirms interest. 2.0x confirms stronger participation.
Rising trading value is required for higher-confidence moves.
20 suggests trend activation. 25 is stronger trend confirmation when +DI is above -DI.
