求助高手MACD指标顶（底）背离量化公式

DIFF:EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:EMA(DIFF,9);
MACD:2*(DIFF-DEA), COLORSTICK,LINETHICK2;
Zero : 0;
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,0,0.03,6,0),COLOR00FF00;
底背:DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORFF00FF;
DRAWTEXT(底背离,-0.2,' 底背离'),COLORFF00FF;
A2:=BARSLAST(REF(CROSS(DEA,DIFF),1));
顶背离:=REF(CLOSE,A2+1)DIFF AND CROSS(DEA,DIFF);
顶背:DRAWLINE(A2=0,DEA,顶背离,DEA,0),colorgreen;
DRAWTEXT(顶背离,DEA*1.15,'顶背离'),colorwhite;
DRAWICON(CROSS(DIFF,DEA),DEA,'BUY');
DRAWICON(CROSS(DEA,DIFF),DEA,'SELL');
