  • Options and the weekly trend are not yet giving the same message.

Priced Move

Where the chain says movement becomes exceptional

Size, not direction · through 21 Aug

Options imply 25.31 to 32.21. Max pain at 30.00 sits inside that range, 4.3% above spot.

Spot Max pain
25.3128.76 ± 3.4532.21
Confirmation level

A close beyond 32.21 or below 25.31 at the 21 Aug expiry would exceed the move currently priced by this chain.

Important limitation

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

  • No material coverage gap was detected in the retained chain.

Aggregate chain data supports concentration, participation and pricing analysis. It does not identify trade aggressor, opening versus closing activity, multi-leg intent or dealer inventory.

Options Intent Radar

Multi-expiry position-maintenance candidate

70/100
Primary intent Multi-expiry position-maintenance candidate

Activity is spread across expirations with heavier open interest than current volume, which can be consistent with position maintenance.

Flow vs price divergence Bullish flow confirms price

Options pressure and weekly price action are pointing in the same constructive direction.

Why this matters

Multi-expiry position-maintenance candidate matters because it connects the options headline to the actual evidence: $466965 of estimated gross traded notional, calls · 91+ days · otm, and a bullish flow confirms price backdrop. Use it as a research priority signal, then validate the chart, liquidity, event calendar, and risk before acting.

Aggregate chain data does not identify trade aggressor or opening versus closing activity; call/put concentration is not proof of market direction. Roll detection is conservative because opening and closing legs are not directly observable in this snapshot.
