将出现买（红色）为预警公式

编写要求：

X1: 0; VAR1:=MA(CLOSE,5); VAR2:=MA(CLOSE,10); VAR3:=MA(CLOSE,20); VAR4:=MA(CLOSE,30); VAR5:=(VAR1+VAR2+VAR3+VAR4)/4; VAR6:=(VAR5-REF(VAR5,5))/REF(VAR5,5)*1500; VAR7:=(VAR5-REF(VAR5,5))/REF(VAR5,5)*1500; VAR8:=EMA(VAR6,8); VAR9:=TROUGHBARS(3,15,1)<10; VAR10:=PEAKBARS(3,15,1)<10; VAR11:=IF(VAR9=1,50,0); VAR12:=IF(VAR10=1,50,0); 底部1:= IF(VAR11=50,50,0); 头部:= IF(VAR12=50,100,0); AB:IF( 底部1>REF(底部1,1),50,0),COLORRED; AA:IF(头部>REF(头部,1),50,0),COLORGREEN; DRAWTEXT(AB=50,40,'买' ),COLORRED,LINETHICK2; DRAWTEXT(AA=50,40,'卖'),COLORFFFFFF,LINETHICK2;

解答：

?VAR1:=MA(CLOSE,5);

VAR2:=MA(CLOSE,10);
