volume-open-interest

当用户要用量能（交易量）与持仓兴趣来验证价格信号、判断趋势健康度，或理解胀爆/抛售高潮、交易商分类报告（COT）等时激活。 核心是"价格第一、量能第二"，量能只是验证价格的旁证。 不适用于：单纯画价格线（转 trend-tools）、摆动指数超买超卖（转 oscillators-contrarian）。 关键 trigger 词：成交量验证、持仓兴趣、量价背离、突破量能、胀爆、抛售高潮、COT、交易商分类报告。 Activate when the user wants to use volume and open interest to confirm price signals, judge trend health, or understand blowoffs/selling climaxes and the COT (commitments of traders) report. The core is "price first, volume second" - volume is only corroborating evidence. Not applicable: simply drawing price lines (-> trend-tools), oscillator overbought/oversold (-> oscillators-contrarian
