通达信七色魔柱指标（超买超卖型）指标公式

买卖信号

1. **买入信号（多方信号）**：当a1>=a2时，显示蓝色柱状线（多头趋势） 2. **卖出信号（图标信号）**：drawicon(a1>=70 and a1>a2 and v<ref(v,1) and c<ref(c,1)*1.03,0.8,1) - 当满足以下条件时显示图标： - a1>=70（短期超买） - a1>a2（短期强于长期） - v<ref(v,1)（成交量萎缩） - c<ref(c,1)*1.03（涨幅小于3%）

用法

1. **适用场景**：该指标为变动率指标（类似RSI的变体），用于判断短期超买超卖状态 2. **信号解读**： - 蓝色柱状线（a1>=a2）表示短期多头趋势 - 白色柱状线（a1<a2）表示短期空头趋势 - a1>=70-80区域显示多层颜色带，表示超买程度加深 - drawicon出现在超买+量价背离时，提示短期风险 3. **注意事项**：该指标侧重短期波动，超买信号不一定立即下跌，需结合其他指标综合判断
