Alert Levels
How Level 1–5 is determined for RVOL and Mover alerts. All alerts use levels 1–5 only (there is no Level 6 or higher).
RVOL Alert Levels
Level is based on how many times current volume is above the baseline (per-minute average). Alerts fire at 1.25× or higher (open window 9:30–11:00 ET and extended hours) or 1.5× or higher (mid-day 11:00 AM–4:00 PM ET). Level 1–5 is assigned from the table below once the minimum is met.
| Level | RVOL threshold |
|---|---|
| 1 | ≥ 2.0× |
| 2 | ≥ 2.5× |
| 3 | ≥ 4.0× |
| 4 | ≥ 6.0× |
| 5 | ≥ 10.0× |
Mover Alert Levels
Level is based on the 1-minute price move (open → close or high–low range, whichever is larger). Alerts fire at ≥ 1.5% effective move (same for all sessions). Level 1–5 is assigned from the table below.
| Level | Min 1-min move |
|---|---|
| 1 | ≥ 1.5% |
| 2 | ≥ 2% |
| 3 | ≥ 3% |
| 4 | ≥ 4% |
| 5 | ≥ 5% |
