Contract Trading

Unified collateral and portfolio margin can improve capital efficiency, but they also tie more positions to one liquidation framework.

期权、期货和永续合约的风险形态不同。选择工具前，应先明确是要固定权利金风险、线性敞口，还是连续杠杆。

Options, futures and perpetual swaps carry different risk shapes. The right choice depends on whether the trader wants defined premium risk, linear exposure or continuous leverage.

移动止损不是自动锁利工具，交易者在使用前仍要设定激活价格、回调比例、触发价格和仓位大小。

A trailing stop is not a magic profit lock; traders still need to choose activation price, callback rate, trigger type and position size before using it.

比特币维持在六万多美元区域，但期货未平仓合约、ETF 需求和 Coinbase 溢价比单一价格更能说明反弹质量。

Bitcoin has held near the mid-$60,000 area, but falling futures open interest and weak ETF demand make rally quality more important than the headline price.

永续合约交易者应把资金费率同时看作持仓成本和拥挤度信号，尤其是持仓跨过多个结算窗口时。

Perpetual futures traders should treat funding as both a holding cost and a crowding signal, especially when a position is kept through multiple funding windows.

如果出场计划要等开仓后才补，期货订单就是不完整的。交易者应在点击买入或卖出前确定触发逻辑、仓位、杠杆和失效位置。
