源码：jj:=(HIGH+LOW+CLOSE)/3;qj0:=vol/IF(HIGH=LOW,4,HIGH-LOW);
qj1:=IF(CAPITAL=0,qj0*(jj-MIN(CLOSE,OPEN)),qj0*IF(HIGH=LOW,1,(MIN(OPEN,CLOSE)-LOW)));
qj2:=IF(CAPITAL=0,qj0*(MIN(OPEN,CLOSE)-LOW),qj0*IF(HIGH=LOW,1,(jj-MIN(CLOSE,OPEN))));
qj3:=IF(CAPITAL=0,qj0*(HIGH-MAX(OPEN,CLOSE)),qj0*IF(HIGH=LOW,1,(HIGH-MAX(OPEN,CLOSE))));
qj4:=IF(CAPITAL=0,qj0*(MAX(CLOSE,OPEN)-jj),qj0*IF(HIGH=LOW,1,(MAX(CLOSE,OPEN)-jj)));
qj5:=qj1+qj2;qj6:=qj3+qj4;DD:=(qj5-qj6)/(qj5+qj6)*100;
DDZ:DD*17,LINETHICK0;DDZ1:DD*13,LINETHICK0;
FILLRGN(DDZ,DDZ1,DDZ>=DDZ1,RGB(255,0,0),DDZ DRAWTEXTREL(10,0,'大单分差'),Color00EEFF;
DRAWTEXTREL(600,900,'证券代码: '+STKLABEL+' 证券名称: '+STKNAME+''),ColorEEBB88;

请老师将公式更改为：DDZ上涨（也就是说DDZ较昨日上涨）或DDZ大于0的选股公式~！

谢谢老师~！，谢谢
