九毛八公式指标
统计一个月内出现macd底背离，无论在一个月内什么时间都可以。
公式模块：
VAR1:=C-REF(C,1);
VAR2:=100*EMA(EMA(VAR1,6),6)/EMA(EMA(ABS(VAR1),6),6); MA5:=EMA(C,5); MA13:=EMA(C,13); UP:=DRAWLINE(L=LLV(L,BArslAST(crOSS(MA13,MA5))+1),LLV(L,BARSLAST(CROSS(MA13,MA5))+1),H=HHV(H,BARSLAST(CROSS(MA5,MA13))+1),HHV(H,BARSLAST(CROSS(MA5,MA13))+1),0); DOWN:=DRAWLINE(H=HHV(H,BARSLAST(CROSS(MA5,MA13))+1),HHV(H,BARSLAST(CROSS(MA5,MA13))+1),L=LLV(L,BARSLAST(CROSS(MA13,MA5))+1),LLV(L,BARSLAST(CROSS(MA13,MA5))+1),0); HR:=HHV(HIGH,55); HRY:=LLV(LOW,55); HRY11:=HR*HRY; HRY33:=SQRT(HRY11); 短牛:=(LLV(VAR2,2)=LLV(VAR2,7) AND COUNT(VAR2<0,2) AND CROSS(VAR2,MA(VAR2,2))) AND REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1); 中牛:=REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1) AND C<HHV(H,21)*0.82; 大牛:=REF(DOWN,1)<REF(DOWN,2) AND UP>REF(DOWN,1) AND C<HRY33; 选三牛合一:短牛+中牛+大牛=3;
