『低买高卖』套装，捕捉短线买卖点，低吸高抛波段战法 擒龙抓妖必备神器！
这套通达信低买高卖指标公式，融合EMA均线系统、自定义KDJ震荡指标和斐波那契回撤位，是一套完整的短线趋势交易系统。
主图核心功能： 红色3日EMA上穿紫色20日EMA时，自动标注「低买」信号（黄色文字）；反之标注「高卖」信号（白色文字），配合买卖图标一目了然。同时显示924天斐波那契关键位（0.191/0.382/0.5/0.618/0.809），精准定位支撑压力位。
公式用法： 专筛「低买」信号，条件为三重EMA金叉+短期均线在长期均线上方，配合MACD金叉死叉逻辑，短线胜率极高。
附赠超短趋势副图： 整合5/13/21/43/55多周期KDJ指标公式，金叉死叉共振提示买卖时机。
使用方法：
主图+副图+三合一，出现「低买」+金叉共振时介入，「高卖」+死叉共振时离场。适合超短线打板族，告别追涨杀跌！
