MACD顶背离和底背离自动画线，通达信和大智慧的都有

DIFF:EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:EMA(DIFF,9);
MACD:2*(DIFF-DEA), COLORSTICK; 
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
底背离:=REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA);
STICKLINE(底背离,0,0.1,8,0),COLORRED;
DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK2;
A2:=BARSLAST(REF(CROSS(DEA,DIFF),1));
顶背离:=REF(CLOSE,A2+1)<CLOSE AND REF(DIFF,A2+1)>DIFF AND CROSS(DEA,DIFF);
DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLORGREEN,LINETHICK2;
