“三和均线交易主图”是一款融合短、中、长期多组均线的智能交易系统，通过三重周期（5–15日、60–80日、230–270日）EMA与MA均线组合，构建出高灵敏度的趋势识别框架。公式以青色、绿色、蓝色分别标识不同周期均线，并用洋红/红色高亮连续3日上涨的均线，直观反映各周期动能方向。
核心亮点在于“多头排列”与“空头排列”的严格判定逻辑——不仅要求长周期均线呈标准排序，还需全部均线连续3日上扬（或下挫），配合价格对全部短期均线的强势穿越，形成高胜率交易信号。当出现“★多”或“★空”提示时，系统同步绘制醒目的红绿K线，助你第一时间锁定趋势启动点。
该公式兼顾趋势稳定性与反应速度，适用于波段及中线交易者，在震荡市中过滤假信号，在趋势行情中牢牢抓住主升浪或主跌浪，是提升交易纪律与胜率的利器！
