根据香港交易所规则，当您在港股期权到期日仍持有价内期权合约，且其价内幅度达到或超过 1.5%，该合约将默认自动行权。
如果合约未满足自动行权条件，且您未在到期前主动行权，则该合约将自动作废，价值归零。
行权时需要您账户内有足够的资产支持：
看涨期权：行权需支付资金，买入对应数量的标的股票；
看跌期权：行权需交付标的股票，卖出对应数量。
如账户资产不足，平台可能采取以下措施：
1、临时借出资金或标的股票，供您完成行权（可能产生利息费用）；
2、到期前强制平仓，尤其是持有看跌期权但缺乏足够股票的情况；
3、取消自动行权设置，避免风险扩大。
✅ 建议您： 如计划持仓到期，请提前准备充足的资金或标的证券，或主动平仓，避免因资产不足而带来额外费用或风险。
