Movers

April 19, 2026 - April 20, 2026, the price of '16°C' steadily climbed from 26c to 43.5c, while '18°C' plummeted from a high of 32c to 11.5c, and '15°C' retreated from 25c to 12.5c. This occurred because, as the resolution date approached, weather forecasting models converged, confirming that the high temperature at Shanghai Pudong Airport would likely land in the 16°C-17°C range, prompting the market to dump outlier options and consolidate around 16°C.
