How can precious metal CFDs be included in an asset portfolio without losing control? This article analyzes the CFD allocation of precious metals from the perspective of asset management: first clarify the contract attributes and overnight holding costs, then use leverage to convert the retracement scale, and use the position calculator to inverse the number of lots; control risks through stop loss, trailing stop loss, and OCO layered defense lines, dismantle spreads, swaps, and slippage costs item by item, and convert gold and silver exposures into executable combination parameters to prevent leveraged precious metal positions from getting out of control in extreme fluctuations.
