The contract's mark price will follow standard algorithms. However, since the external markets referenced by this product index have specific trading cycles, during non-standard trading hours, the index price of the contract will enter a quote-holding state, meaning the index price will continue to use the last valid quote before entering this period. Users are advised to closely monitor the activity of external reference sources when trading such contracts, set take-profit and stop-loss levels reasonably, and guard against price fluctuation risks caused by changes in liquidity. **Gate DEX Team** **January 27, 2026**
