- Reach probability = how likely SPX touches this cluster level today
- Based on distance from spot + Total Options RVOL tier
- Fragile (>60% 0DTE) = likely reached but won't hold/bounce
- Sticky (<30% 0DTE) = harder to reach but bounces if touched
- Normal (30-60% 0DTE) = balanced behavior
- RVOL reliable after 9:00 AM PT — treat pre-9AM values as preliminary
- Grade A = high confluence of OI + GEX + distance scoring
- DEAD clusters = lifecycle expired (no new snapshots confirming level)
Reach Probability Table by Distance:
| Distance from Spot |
LOW RVOL |
NORMAL RVOL |
HIGH RVOL |
| ≤ 25 pts | 80-90% | 85-95% | 90-97% |
| 26-50 pts | 55-75% | 60-80% | 70-88% |
| 51-75 pts | 35-55% | 40-60% | 50-70% |
| 76-100 pts | 20-35% | 25-40% | 35-50% |
| > 100 pts | <20% | <25% | <35% |
RVOL Gate Interpretation:
- HIGH RVOL (≥1.25) — clusters are strong magnets, high follow-through
- ELEVATED RVOL (0.85-1.25) — moderate cluster magnetism
- NORMAL RVOL (<0.85) — weaker pull, range may compress
- Confirmed RVOL = consistent over last 30 min window
Color Guide:
■ Green = reach >80%
■ Yellow = reach 60-80%
■ Red = reach <60%
■ Orange badge = fragile
