通达信的三个指标（DDX\DDY\DDZ)存在一个DDZ的图形与DDX、DDY不一致的情况，如何修改呢？我们先来看这三个指标的源码：
一、DDX（原码）：参数N=10
大单动向:(LARGEINTRDVOL-LARGEOUTTRDVOL)*10000/FINANCE(7),NODRAW;
DDX0_MA:MA(大单动向,5);
STICKLINE(大单动向>0,0,大单动向,2,0),COLORRED;
STICKLINE(大单动向<0,0,大单动向,2,0),COLORCYAN;
涨跌动因:IF(TRADENUM>0,(TRADEOUTNUM-TRADEINNUM)*100/TRADENUM,0),NODRAW;
DDY0_MA:MA(涨跌动因,5);
STICKLINE(涨跌动因>0,0,涨跌动因,2,0),COLORRED;
STICKLINE(涨跌动因<0,0,涨跌动因,2,0),COLORCYAN;
大单差分:IF(TRADENUM>0,(LARGETRDINNUM-LARGETRDOUTNUM)/TRADENUM*100,0),NODRAW;
DDZ0_MA:MA(大单差分,5);
STICKLINE(大单差分>0,0,大单差分,2,0),COLORRED;
STICKLINE(大单差分<0,0,大单差分,2,0),COLORCYAN;
