主题：请老师解决画线问题！

1.

//逐k线计算

 

h1:=hhv(h,10);
if ref(h,1)<h then h2:h1;

 

2.

//序列计算
h1:=hhv(h,10);
drawline(h1<refx(h1,2),h1,h1>ref(h1,2),h1,0);

1是h2

2是划线，无数值

你举的例子就不行，划线就是划线，确定AB点后一条线，这条线仅仅是线，无数据的

input:m(5),n(10);
ma5:ma(c,m);
ma10:ma(c,n);

if cross(ma5,ma10) then begin
 sellshort(holding<0,0,thisclose);
 buy(holding=0,1,thisclose);
end

if cross(ma10,ma5) then begin
 sell(holding>0,0,thisclose);
 buyshort(holding=0,1,thisclose);
end

直线不行，

MA5:MA(CLOSE,5);
MA20:MA(CLOSE,20);
MA30:MA(CLOSE,30);
MA60:MA(CLOSE,60);

 

l1:LINEVALUE(CROSS(MA5,MA30) ,h ,CROSS(MA20,MA60) ,h ,0 ,0 );
l2:LINEVALUE(CROSS(MA30,MA5) ,l ,CROSS(MA60,MA20) ,l ,0 ,0 );

 

enterlong:c>l1,tfilter;

exitlong:c<ref(llv(l,10),),tfilter;
