这套公式包含**低买高卖主图指标**、**超短趋势副图指标**、**低买选股公式**，是专为短线交易打造的全套指标组合。主图基于均线、EMA、高低点估值算法，精准标注低买、高卖文字信号，搭配买卖图标提示，同时显示黄金分割压力支撑位；副图通过多周期均线平滑计算，研判短趋势与超短趋势，金叉共振看涨、死叉共振看跌；选股公式锁定低买信号触发条件，一键筛选短线起爆个股，无未来函数，信号不漂移。
使用方法
1. 主图：出现黄色**低买**文字+买入图标为建仓信号，白色**高卖**文字+卖出图标为止盈信号，结合黄金分割线判断压力支撑；
2. 副图：红色短趋势为上涨趋势，黄色金叉共振加仓，紫色死叉共振减仓；
3. 选股：盘中/盘后执行低买选股，同步匹配主图低买信号，共振买入成功率更高。
