Gate will upgrade the risk limit mechanism for Futures Trading in batches starting from July 29, 2025. The new mechanism will remove the manual selection of risk limit levels by users, instead, the system will automatically select the risk limit level based on the existing Position value. This upgrade optimizes the logic for maintaining Margin calculations, changing from a fixed level Margin rate calculation to a gradient calculation based on Position value. Taking the BTCUSDT market as an example, for a Position valued at 1.2 million USDT, the maintenance Margin requirement under the new mechanism drops from 6000 USDT to 4900 USDT, effectively reducing the user's Liquidation risk.
