同花顺软件公式，行12：语法错误，变量<df>未定义

Question

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=(SMA(RSV,3,1));
D:=(SMA(K,3,1));
KK:=INTPART(SMA(RSV,3,1));
DD:=INTPART(SMA(K,3,1));
N:KK+DD,COLORff00ff,LINETHICK2;
预测:IF(CROSS(N,50),90,50),COLOR00FF00;
涨停:IF(CROSS(N,100),100,50),COLORYELLOW;
ZTSJ:=BARSLAST(涨停=100);
价:REF(C,ZTSJ)*1.1,COLOR0000FF,POINTDOT,LINETHICK0;
涨:(C/REF(C,ZTSJ)-1)*100,COLOR99FF00,LINETHICK0;
低:IF(ZTSJ>0 AND ZTSJ<10 AND (L/REF(C,ZTSJ)-1)*100<=-DF,5,50),COLORWHITE;
达标:=ZTSJ<20 AND CROSS(H,REF(C,ZTSJ)*1.1);
GWGD:=N<REF(N,1) AND REF(N,1)>=160 AND REF(N,1)>=REF(N,2);
风险:IF(GWGD,95,160),COLOR00ff00;

{以下设置副图显示方式}
100,COLORWHITE,POINTDOT;
STICKLINE(C,100,100,4,0),COLORWHITE;
STICKLINE(达标,50,100,4,0),COLOR0000FF;

Answer 1

你这个是做什么用的？错误说的是在语句中的DF找不到对应的值。告诉我用法应该可以帮你完善。
