KuCoin will implement changes to the tick sizes for the ARTY-USDT and SCR-USDT spot trading pairs on March 23, 2026, at 8:00 UTC. This adjustment is intended to enhance market liquidity and improve the trading experience for users. Existing orders will remain unaffected, and API users should refer to the GET /api/v2/symbols endpoint for the updated tick sizes. While open and historical orders will display the new tick sizes, they will be executed based on the original tick sizes. Traders are advised to update their strategies in response to these changes.
