[求助]请老师帮忙写个模型代码

VARIABLE:n=0,m=0;
ma15:ma(c,15);
hh:hhv(h,enterbars+1);
if c>ma15+5 then buy(holding=0,1,market);

if h-enterprice>=3 and  h-enterprice<=10 then n:=1;
if l-enterprice<=3 and n=1 then begin
 sell(holding>0,holding,market);
 n:=0;
 end
if h-enterprice>10 then m:=1;
if l-enterprice<=0.7*(hh-enterprice) and m=1 then begin
 sell(holding>0,holding,market);
 m:=0;
 end
 if enterprice-l>=15 then sell(holding>0,holding,market);
