KuCoin will implement changes to the tick sizes for LAVA-USDT, GAIN-USDT, and PLANCK-USDT trading pairs on March 19, 2026, at 8:00 UTC. This adjustment is intended to enhance market liquidity and improve the trading experience. 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 adjust their strategies accordingly.
