本主图指标聚焦“低吸”与“打板”双重机会筛选。蓝色“主趋势线”向上运行时，表明行情处于强势阶段；K线颜色暗藏市场动能特征——紫色或蓝色K线代表强势，下跌时显示绿色；当K线转为青色，则预示短期行情强劲。
需重点关注两大核心信号：其一为紫色“★低吸”信号（配24号图标），该信号触发需同时满足三个条件——主趋势线金叉0轴、筹码集中度处于0-100区间、技术指标共振值为正，此时构成安全低吸点位；其二为紫色“★打板”信号（配9号图标），触发条件为当日涨幅超过5%且成交量萎缩、筹码分布值低于150，符合条件时即为强势打板机会。
该指标通过主趋势线方向、K线颜色变化及信号系统，形成完整的低吸打板选股逻辑，适用于打首板策略的实战操作，帮助投资者精准捕捉市场机会。
