编写要求：

请哪位帮我改一下LXDDX指标.没正版数据.下载长风数据后当天总是为0 input:p1(60),p2(5),p3(10); TODAY:= "ddx.ddx"=0; {判断是否当天} P:=MIN(COUNT(ORDER(2),0),P1); P:=IF(P=0 and TODAY,1,P); OK:="DDEDATA@CHECK">=1;{判断数据是否完整} IF OK THEN DDX:=IF(TODAY,"DDEDATA@BIGORDER"(1)-"DDEDATA@BIGORDER"(2),BIGORDER(1)-BIGORDER(2))*vol/capital*100; ELSE DDX:=IF(TODAY,"DDEDATA@DDEDATA"(0),(BIGORDER(1)-BIGORDER(2))*vol/capital*100); DDX:DDX,COLOR3D; DDX1:EMA(DDX,p)*p,color00ffff,LINETHICK1; DDX2:MA(DDX1,p2),colorff00ff,LINETHICK1; DDX3:MA(DDX1,p3),color00ff00,LINETHICK1; 1,dotline,colorblue; drawtextabs(0,0,'大单动向');

解答：

?{DDX}

INPUT: P1(60,0,100),P2(5,0,100),P3(10,0,100);
