老师好！帮忙看看，这个通达信公式通不过，请改一下。谢谢。

 
测试公式时，出现错误：绘图函数不可支持变量赋值。
 
DIF:EMA(CLOSE,12)-EMA(CLOSE,26),COLORRED,LINETHICK2;
DEA:EMA(DIF,9),COLORWHITE,LINETHICK2;
MACD:(DIF-DEA)*2,COLORSTICK;
 A1:=BARSLAST(REF(CROSS(DIF,DEA),1));
底背离:=REF(CLOSE,A1+1)>CLOSE AND DIF>REF(DIF,A1+1) AND CROSS(DIF,DEA);
STICKLINE(底背离,0,0.03,6,0),COLOR00FF00;
底背:DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK4;
底背:DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK4;
DRAWTEXT(底背离,0.12,' 底背离'),COLORFF00FF;
A2:=BARSLAST(REF(CROSS(DEA,DIF),1));
顶背离:=REF(CLOSE,A2+1)<CLOSE AND REF(DIF,A2+1)>DIF AND CROSS(DEA,DIF);
顶背:DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLORGREEN,LINETHICK4;
