反包龙是专为A股短线交易打造的龙头股反包起爆捕捉指标，融合均线趋势、筹码分布、动量强弱多重核心算法，专门识别个股回调后的反包反转机会，精准适配短线抓龙、隔日套利、趋势反转交易场景，是通达信实用的短线抓涨停辅助指标。
指标核心逻辑：
通过13/34期EMA均线差值计算市场动量，结合34日高低区间量化股价强弱，叠加筹码胜率、筹码集中度交叉信号，同时校验10日、60日指数均线趋势，过滤下跌趋势虚假反包信号，精准锁定强势个股低位反包、趋势反转的起爆节点。
使用方法：
1、主图红线为核心趋势线，红线延续代表多头趋势，拐头则趋势走弱；
2、红蓝、紫红实体K线为强弱反包信号，青色细K线叠加双重确认信号，可靠性更高；
3、出现29、34号图标及“反包龙”文字标记，为优质起爆买点；
4、公式XG信号为精选趋势反包龙头标的，适合短线低吸、半路介入，规避弱势反弹陷阱。
