Risk management of precious metals CFD trading requires systematic engineering supported by tools. This article starts from the risk budget: the risk of a single transaction should not exceed 1%-2% of the account, and the principle is converted into lots using a position calculator; stop-loss, stop-profit and trailing stop-loss are embedded when opening a position, and the OCO combination order forms a closed-loop risk control; in the position stage, the liquidation distance is dynamically deduced through the margin monitoring dashboard, cross-variety risk aggregation and interactive simulator, the visual risk scale replaces the static margin rate, and a complete risk control tool chain is built with negative balance protection.
