编写要求：

WY1001:=(2*CLOSE+HIGH+LOW)/4; WY1002:=EMA(WY1001,4); WY1003:=EMA(WY1002,4); WY1004:=EMA(WY1003,4); XYS0:(WY1004-REF(WY1004,1))/REF(WY1004,1)*100; STICKLINE(XYS0>=0,XYS0,0,1,0),COLORRED; STICKLINE(XYS0<0,XYS0,0,1,0),COLORGREEN; PJGJ:=AMOUNT/VOL/100; SSRYDJX:=MA(PJGJ,13); SSRCJL:=EMA(VOL,13); SSRCJE:=EMA(AMOUNT,13); SSRCBJX:=SSRCJE/SSRCJL/100; CYS13:=(CLOSE-SSRCBJX)/SSRCBJX*100; XYSHSL:=EMA(VOL/CAPITAL*100,13); ZZX:0,COLORWHITE; STICKLINE(XYSHSL>6.1 AND CYS13>5 ,2 ,0 ,1 ,0 ),COLORGREEN; STICKLINE(XYSHSL>3.8 AND CYS13>5 ,1.5 ,0 ,1 ,0 ),COLORYELLOW; STICKLINE(XYSHSL>2.1 AND CYS13>5 ,1 ,0 ,1 ,0 ),COLORCYAN; STICKLINE(XYSHSL>1.8 AND CYS13>5 ,0.5 ,0 ,1 ,0 ),COLORBLUE; XYS1:MA(XYS0,2); XYS2:MA(XYS0,1); DRAWICON(CROSS(XYS1,XYS2),XYS1,2); DRAWICON(CROSS(XYS2,XYS1),XYS2,1);

解答：

?WY1001:=(2*CLOSE+HIGH+LOW)/4;

WY1002:=EMA(WY1001,4);
