Why did it move?

Structured · 2 factors
  1. 1

    Resolution-risk signal firing

    Expires in 5982h with open resolution ambiguity.

  2. 2

    Wide spread — 5.0¢

    Bid-ask spread is wide enough that intraday moves overstate any tradeable edge. Most of the headline pp move would be eaten by spread on a market order.

What to track next

  • Verify the resolution source on this page — exchange feed, official release, news consensus — before treating any move as new information.

Verification actions only — never trade recommendations.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.
