Magnet Strength Details →

1.85× High (1.5–2×)

Current OI 40,365

30d Avg OI 21,790

Elevated OI — dealers carry larger hedges, making price walls structurally stronger.

Put/Call Ratio

0.91

NEUTRAL

Between 0.8–1.2 — balanced positioning. No strong directional lean from options flow alone.

Dominant Wall

$1120

▲ Above spot

The highest OI concentration strike — the structural anchor dealers are most committed to hedging.

Distance to #1 Wall

$-98.12

-9.60%

Price is below the dominant wall — acts as resistance.

Wall Skew

+1.000

CALL HEAVY

Call-heavy at the dominant wall — call sellers cap rallies toward it. Acts as resistance.

Today's Top Setup — COST

SQUEEZE, PIN, and CAGE scored 0–100 from OI structure. Highest score = today's highest-conviction setup.

PIN — 53.7% hit rate (n=1,719). CAGE — 45.4% (n=1,161). SQUEEZE — 49.5% (n=5,555). Half hit, half don't — the edge is asymmetric payoff.

Dealer Magnet Strength

When total OI is elevated vs its 30-day rolling average, dealer hedging is heavier — walls act like magnets. Very High = stronger PIN / CAGE conviction. Near-normal = weaker structural hold.
