黑马线公式中 机会来临 做个选股预警公式

编写要求：

A1:=3*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1)-2*SMA((C-LLV(L,55))/(HHV(H,55)-LLV(L,55))*100,5,1); 黑马线:=EMA(A1,5),LINETHICK2 ; A2:=(黑马线-REF(黑马线,1))/REF(黑马线,1)*100; A3:=EMA(C,5); A4:=((C-LLV(L,21))/(HHV(H,21)-LLV(L,21)))*100; 趋势线:=(MA(3*SMA(A4,6,1)-2*SMA(SMA(A4,5,1),5,1),2)) ; A5:=(HHV(H,60)-C)/(HHV(H,60)-LLV(L,60))*100; 底部:(A2<-10 AND A2>REF(A2,1))*25,COLORYELLOW; DRAWICON(底部 AND A3>REF(A3,1),25,4); 机会来临:REF(IF((MA(C,5)-C)/C>0.04 AND (MA(C,10)-MA(C,5))/MA(C,5)>0.04,30,0),1)*1.5,COLORRED; A6:=C>REF(C,1) AND V>REF(C,1); 低位金叉:(CROSS(趋势线,黑马线) AND 趋势线<20 AND 黑马线<20 AND A6)*25,COLORFFFFFF;

解答：

?机会来临:REF(IF((MA(C,5)-C)/C>0.04 AND?

(MA(C,10)-MA(C,5))/MA(C,5)>0.04,1,0),1);
