How it works
- 1
Mark what already happened
Every airport weather report since local midnight sets the high-water mark. The official high can't finish below it, so every range under it is out.
- 2
Forecast what's left
82 forecast runs (GFS and ECMWF) cover the remaining hours, corrected by how far off the forecast has been today.
- 3
Price every range
Thousands of simulated finishes become a probability and a two-sided quote for each of Gemini's contracts, refreshed every minute.
