这套大单降龙通达信指标公式包含主图、副图、三大模块，是专为短线交易者打造的主力资金监控系统，融合布林带与大单资金流向算法，助你锁定强势突破个股。
主图公式基于30日均线±2倍标准差构建压力支撑通道，当大单净买入≥200万、涨幅≥3%且突破上轨时，自动标注紫色K线+买入图标，直观呈现主力拉升信号，是非常实用的主图指标公式。
副图公式采用MTM动量轨迹结合洗盘/进场/拉高/出货四色柱状图——红色代表洗盘，蓝色代表进场，黄色代表拉高，青色代表出货，清晰判断主力资金动向，堪称股票技术分析必备的副图指标。
公式在主图逻辑上叠加换手率>10%的过滤条件，13周期去重避免重复信号，一键筛选具备大单突破特征的强势股，是高效的通达信公式。
使用方法：
主图+副图叠加效果最佳，出现紫色K线+副图蓝色柱时为最佳介入点；公式直接在通达信条件中运行，适合追踪资金流向的短线投资者！
