信号较多，还需要结合成交量过滤一些票，信号出现后量开始放大，较适合参与
指标使用到COST函数，需要下载完整盘后数据
{副图}
VAR1:=MA(COST(80),20);
VAR2:=100*(VAR1-REF(VAR1,13))/VAR1;
VAR3:=10*(VAR1/MA(CLOSE,30)-1);
VAR4:=COUNT(VAR2<1,20)>10 AND COUNT(VAR3<2.382,10)>5;
信号未精选:FILTER(CROSS(CLOSE,VAR1),5) AND COUNT(CROSS(MA(CLOSE,3),VAR1),60)<2 AND VAR4 AND (VAR1-REF(VAR1,20))/VAR1<0.02,COLORGRAY,LINETHICK3;
DRAWTEXT(信号未精选,0.8,'潜力主升浪'),COLORGREEN;
