老师，帮我编个MACD (文华财经WH6赢顺V6.7)

 帮我把以下的MACD快慢线，就是白色和黄色经金叉时，用向上红上箭头提示，死叉时，用绿色向下箭头表示，谢谢了

VAR1:=REF(CLOSE,1);
 VAR2:=SUM(VOL,2)/((HHV(HIGH,2)-LLV(LOW,2))*100);
 VAR3:=(CLOSE-VAR1)*VAR2;
 VAR4:=SUM(VAR3,0);
 VAR5:=SMA(VAR4,5,1);
 VAR6:=SMA(VAR4,8,1);
 OSC: VAR5-VAR6;
 OSCMA: MA(OSC,4);
 OSC, COLORSTICK;
 VD: SUM(IF(OSC>0,OSC*1.003,OSC*1.003>0),34)/34;
 VE: SUM(IF(OSC<=0,OSC*0.97,OSC*0.97<0),34)/34;
DRAWTEXT(CROSS(OSCMA,VE),OSCMA,'买'),COLORRED;
 DRAWTEXT(CROSS(VD,OSCMA),OSCMA,'卖'),COLORGREEN;
