Why did it move?

Structured · 3 factors
  1. 1

    Up 8pp over 24h

    Now 19¢; +2.6pp in the last hour.

  2. 2

    Resolution-risk signal firing

    Expires in 100h with open resolution ambiguity.

  3. 3

    Wide spread — 14.5¢

    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.

Market Description

This market will resolve according to the total precipitation in mm in Hong Kong between April 1 and April 30, 2026, according to the Hong Kong Observatory. The resolution source for this market will be the Hong Kong Observatory, specifically the "Total Rainfall (mm)" figure for all days in April 2026 under the "Daily Extract" at the https://www.weather.gov.hk/en/cis/climat.htm link once figures are finalized for the specified range. If the reported data falls exactly between two brackets, this market will resolve to the higher bracket. If the relevant data is not available by June 7, 2026, 11:59 PM ET, another credible resolution source will be chosen. The resolution source for this market measures precipitation to 1 decimal place (e.g., 1.5), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
