通达信“龙头先锋”主图指标公式解析--横盘蓄势

admin

一、公式解析
这个指标核心：两条虚线划定筹码区间 —— 红色 “龙头启动” 线是短期主力成本线，绿色 “龙头买点” 线是安全介入参考，中间深色带是筹码密集区，站稳红色线且量能跟进，就是强势前兆。“★龙头买点” 信号需满足四重条件：突破 30 天内新高、成交量放大 2 倍以上、涨幅超 3% 且实体占比超 60%（涨势扎实）、前期 30 天振幅低于 20%（横盘蓄势），缺一项都不触发，过滤假龙头。
关键函数解析：COST (70) 是核心筹码函数，代表市场 70% 筹码的持仓成本价。指标中 “龙头买点：EMA (COST (70),10)”，即通过 10 日指数平滑后的 70% 筹码成本价作为买点参考。这个价格意味着抛压相对较小，回踩或站稳这条线时介入，既能依托筹码支撑降低风险，又能紧跟启动节奏，是捕捉安全买点的核心逻辑。
