[文华源码] MACD背离模型

指标、策略模型应用案例: i3 G" v# m- U3 m/ H
    背离又称背驰，是指当股票或指数在下跌或上涨过程中，不断创新低（高），而一些技术指标不跟随创新低（高），称为背离。在背离过程中，升势或跌势会放缓，股价的走势将会逆转。顶背离，意即升势放缓，指数或股价难再企稳于高位，甚至有机会掉头回落；底背离，意即跌势将尽，指数或股价开始见底回升，这属于买入讯号。

以MACD背离为例，编写指标

1. DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26),COLORYELLOW;% x5 N) L: }( Z' g) q7 N
   
2. DEA :=EMA(DIFF,9),COLORGREEN;
   
3. MACD:=2*(DIFF-DEA), COLORSTICK;
   
4. A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
   
5. B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)
   
6. C1:=BARSLAST(REF(CROSS(DEA,DIFF),1));. K( P* S$ k1 {
   
7. D1:=REF(C,C1+1)DIFF AND CROSS(DEA,DIFF);
   
8. DRAWTEXT(B1,L,'▲');//MACD底背离
   
9. DRAWTEXT(D1,H,'▼');//MACD顶背离
