以下是合并后的代码：

DIF:EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:EMA(DIF,9);
MACD:(DIF-DEA)*2;
红面积:SUM(MACD,BARSLAST(MACD<0))*(MACD>0);
绿面积:SUM(MACD,BARSLAST(MACD>0))*(MACD<0);
底背离:REF(CLOSE,BARSLAST(REF(CROSS(DIF,DEA),1))+1)>CLOSE AND DIF>REF(DIF,BARSLAST(REF(CROSS(DIF,DEA),1))+1) AND CROSS(DIF,DEA);
顶背离:REF(CLOSE,BARSLAST(REF(CROSS(DEA,DIF),1))+1)<CLOSE AND REF(DIF,BARSLAST(REF(CROSS(DEA,DIF),1))+1)>DIF AND CROSS(DEA,DIF);

AA:ROUND(REF(绿面积,1)*100);
BB:ROUND(REF(红面积,1)*100);

DRAWNUMBER(CROSS(0,MACD),HHV(REF(MACD,1),5)+0.03,ABS(BB)),COLORMAGENTA;
DRAWNUMBER(CROSS(MACD,0),LLV(REF(MACD,1),5)-0.03,ABS(AA)),COLORGREEN;

IF 底背离 THEN
STICKLINE(底背离,0,0.1,8,0),COLORRED;
DRAWLINE(BARSLAST(REF(CROSS(DIF,DEA),1))=0,DEA,底背离,DEA,0),COLORRED,LINETHICK2;
ENDIF;

IF 顶背离 THEN
DRAWLINE(BARSLAST(REF(CROSS(DEA,DIF),1))=0,DEA,顶背离,DEA,0),COLORGREEN,LINETHICK2;
ENDIF;

其中，底背离和顶背离分别表示 MACD 指标的底部背离和顶部背离，AA 和 BB 分别表示红色和绿色面积的数值，DRAWNUMBER 函数用于在 K 线图上绘制这两个数字，如果存在底部背离则绘制红色线条，如果存在顶部背离则绘制绿色线条。
