买卖信号
**买入信号：** - "买点"指标：当收盘价低于30日内最低价时，通过计算绝对价格变化与最大正变化的比率得出买点信号，以红色柱状线显示 - DRAWICON买入信号1：FILTER(J1>REF(J1,1) AND J1<REF(J1,3) AND J1<K1 AND VAR4>REF(VAR4,1) AND K1>=REF(K1,1) AND J1<40 OR CROSS(J1,K1) AND CROSS(J1,D1) AND J1<50 OR J1>REF(J1,1) AND J1<-20,7)，在J1*0.3位置显示图标7 **卖出信号：** - "卖点"指标：当UPPERS>UPPERL时显示绿色柱状线 - DRAWICON卖出信号：FILTER(J1<=REF(J1,1) AND J1>80,8)，在J1*0.9位置显示图标8
用法
1. **适用场景**：该指标为综合型指标，结合了趋势判断和超买超卖分析，适用于中短期波段操作 2. **买点使用**：当出现红色柱状线的买点信号，或K线图上出现买入图标（图标7）时
