Spot
Max pain
37.9741.32 ± 3.3544.67
Confirmation level

Important limitation
The range is a pricing reference, not a forecast; volatility can reprice sharply after news or as expiry approaches.

Put-heavy activity
Put-side activity dominates. This can reflect hedging or directional positioning, but the chain alone cannot distinguish buying from selling.
Put-side pressure is building while price is rising, a cautionary divergence.
Put-heavy activity matters because it connects the options headline to the actual evidence: $26512 of estimated gross traded notional, puts · 8-21 days · otm, and a bearish flow against rising price backdrop. Use it as a research priority signal, then validate the chart, liquidity, event calendar, and risk before acting.
