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);
