美股期权异动榜:主力资金流向哪里Unusual Options Activity: Where the Flow Is Going

期权异动指某些合约的成交量异常放大,常被用来观察主力资金的方向与情绪。一个关键指标是“量比”——当日成交量除以未平仓量(OI):量比远大于 1,意味着大量新仓在今天涌入,而非旧仓换手,信号更值得留意。

Tickwind 扫描全市场流动性较好的期权,按单合约成交量排名,展示看涨/看跌、行权价、到期日与量比。期权是杠杆工具、且异动未必代表“聪明钱”——它是一个观察情绪的窗口,不构成交易建议。数据来自 Cboe,约延迟 15 分钟。

Unusual options activity means a contract’s volume spikes abnormally — often used to read where flow and sentiment are pointing. A key tell is the volume/open-interest ratio: well above 1 means a lot of new positions opened today rather than old ones changing hands, which is more notable.

Tickwind scans heavily-traded options market-wide, ranks by single-contract volume, and shows call/put, strike, expiry and the volume/OI ratio. Options are leveraged and unusual flow isn’t necessarily “smart money” — it’s a sentiment window, not advice. Data is ~15-min delayed from Cboe.
