有朋友建议用底背离的选股公式选股凡是朋友推荐的，我都要亲自证验一下。所以编了一个MACD、KDJ、RSI 的顶底背离三合公式。底背离可以做选股公式用，顶背离可以做卖出公式用。
公式是从网上学来的。
从公式编程讲，我认为我的编码比他们的更简洁更明了。我把柱线的颜色说明，写进了窗口，没有放在数据栏中。其他没有变。
我写的公式是：
{顶底背离}
DIFF:EMA(CLOSE,12) – EMA(CLOSE,26);
DEA:EMA(DIFF,9);
MACD:2*(DIFF-DEA),COLORSTICK;
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)<DIFF AND CROSS(DIFF,DEA);
A2:=BARSLAST(REF(CROSS(“KDJ.K”(9,3,3),”KDJ.D”(9,3,3)),1));
B2:=REF(C,A2+1)>C AND REF(“KDJ.K”(9,3,3),A2+1)<“KDJ.K”(9,3,3) AND CROSS(“KDJ.K”(9,3,3),”KDJ.D”(9,3,3));
A3:=BARSLAST(REF(CROSS(“RSI.RSI1″(6,12,24),”RSI.RSI2″(6,12,24)),1));
B3:=REF(C,A3+1)>C AND REF(“RSI.RSI1″(6,12,24),A3+1)<“RSI.RSI1″(6,12,24) AND CROSS(“RSI.RSI1″(6,12,24),”RSI.RSI2″(6,12,24));
C1:=BARSLAST(REF(CROSS(DEA,DIFF),1));
D1:=REF(C,C1+1)<C AND REF(DIFF,C1+1)>DIFF AND CROSS(DEA,DIFF);
C2:=BARSLAST(REF(CROSS(“KDJ.D”(9,3,3),”KDJ.K”(9,3,3)),1));
D2:=REF(C,C2+1)<C AND REF(“KDJ.K”(9,3,3),C2+1)>”KDJ.K”(9,3,3) AND CROSS(“KDJ.D”(9,3,3),”KDJ.K”(9,3,3));
C3:=BARSLAST(REF(CROSS(“RSI.RSI2″(6,12,24),”RSI.RSI1″(6,12,24)),1));
D3:=REF(C,C3+1)<C AND REF(“RSI.RSI1″(6,12,24),C3+1)>”RSI.RSI1″(6,12,24) AND CROSS(“RSI.RSI2″(6,12,24),”RSI.RSI1″(6,12,24));
STICKLINE(B1>0,-0.1,0,2,0),COLORRED;
STICKLINE(B2>0,-0.1,0,2,0),COLORFF00FF;
STICKLINE(B3>0,-0.1,0,2,0),COLORYELLOW;
STICKLINE(D1>0,0.1,0,2,0),COLOR00FF00;
STICKLINE(D2>0,0.1,0,2,0),COLORFFCC66;
STICKLINE(D3>0,0.1,0,2,0),COLORWHITE;
DRAWTEXT_FIX(1,0.0,0.0,1,’MACD底背’),COLORRED;
DRAWTEXT_FIX(1,0.1,0.0,1,’MACD底背’),COLORRED;
DRAWTEXT_FIX(1,0.2,0.0,1,’KDJ底背’),COLORFF00FF;
DRAWTEXT_FIX(1,0.3,0.0,1,’RSI底背’),COLORYELLOW;
DRAWTEXT_FIX(1,0.42,0.0,1,’MACD顶背’),COLOR00FF00;
DRAWTEXT_FIX(1,0.52,0.0,1,’KDJ顶背’),COLORFFCC66;
DRAWTEXT_FIX(1,0.62,0.0,1,’RSI顶背’),COLORWHITE;
三种顶背离大体还可以用，尽管MACD的顶背离表达得很不准确
KDJ、RSI底背离也还可以，本例KDJ不精确
KDJ、RSI底背离也还可以，本例RSI不精确
MACD底背离基本不能用，几个有用的波段大底，它毫无表示
将MACD底背离的一行调整成：
B1:=REF(C,A1+2)<REF(C,A1+1)<C AND REF(MACD,2)>=REF(MACD,1) AND REF(MACD,1)<=MACD AND MACD<-0.1;
MACD底背离就可以用了
我在编写的时候，有一个修改过程。
将MACD底背离的一行调整成：
B1:=REF(C,A1+2)<REF(C,A1+1)<C AND REF(DIFF,2)>=REF(DIFF,1) AND REF(DIFF,1)<=DIFF AND MACD<-0.1;
MACD底背离就可以用了，但滞后（因为DIFF滞后）
把DIF换成MACD
B1:=REF(C,A1+2)<REF(C,A1+1)<C AND REF(MACD,2)>=REF(MACD,1) AND REF(MACD,1)<=MACD AND MACD<-0.1;
MACD底背离就不再滞后了
从整个公式来看，没有太大实用价值。大部分背离都是滞后的。晚了就成马后炮了。我们需要的是能有警示和提醒功能的公式。
就MACD、KDJ和RSI三个公式而言，无论抄底还是逃顶，MACD都比KDJ和RSI更准确，更有用。但编成选股公式后，公式设定得太死，无论抄底还是逃顶，都有很多不适用的提示。
