【指标介绍】
1. 指标核心优势
① 无未来、不加密：源码完全公开，无任何隐藏加密环节，也不包含未来函数，避免信号漂移、事后诸葛亮的问题，每一个信号都是实时可验证、可追溯的，放心套用。
② 全套配齐，双端通用：包含1个主图指标+1个副图指标+1个选股指标，通达信手机端、电脑端均可直接导入使用，无需额外修改参数，省去繁琐的适配步骤。
③ 信号精准，过滤性强：摒弃单一均线或价格判断，结合加权收盘价计算和多重均线验证，有效过滤震荡行情中的无效回调信号，只保留趋势中的强势回调机会，降低误判概率。
2. 核心逻辑与信号解读
指标的核心逻辑的是「趋势确认+回调验证」，先通过均线系统确认强势趋势，再通过价格波动判断回调有效性，双重验证后给出信号，具体拆解如下（直白不绕弯，记好这几点即可）：
「趋势确认」—— 均线多头排列是核心前提（缺一不可）：
必须满足4条均线呈多头排列，且全部向上运行，具体要求：13日线＞24日线＞30日线＞120日线，同时每条均线都要高于前一日的均线（120日线可持平）。这一步的目的是确认当前处于强势趋势中，避免在弱势行情中误判信号。
「回调验证」—— 5个条件同时满足，才是有效信号（少一个都不行）：
① 价格回调但未破趋势：当日收盘价站上13日线，但当日最低价曾跌破13日线（说明是合理回调，而非趋势反转）；
② 趋势延续性：当日收阳，说明回调后有资金承接，趋势有延续的动力；
③ 强势度达标：13日均线角度大于47度，角度越高，说明当前趋势越强，回调后的反弹力度也更有保障；
④ 前期有强势基础：过去13个周期内，曾出现过强势拉升（对应源码中强势判定标准），说明标的本身具备强势特质，回调只是暂时休整。
