怎么把oo定义成为 平空 或者平多 处的价位呢？？？
下文定义oo是当日开盘价，我想把它改成 平仓处的价位 ，怎么写呢？求指导
input:grid(3,1,60,1);
variable:level=0;
dist:=barslast(date<>ref(date,1));
oo:=ref(open,dist);
if holding=0 then begin
dnprice:=oo-grid*mindiff;
if low<=dnprice then begin
buy(1,1,limitr,dnprice);
level:=-1;
end
end
if holding=0 then begin
upprice:=oo+grid*mindiff;
if high>=upprice then begin
buyshort(1,1,limitr,upprice);
level:=1;
end
end
if holding>0 then begin
upprice:=oo+(level+1)*grid*mindiff;
dnprice:=oo+(level-1)*grid*mindiff;
if high>=upprice then begin
sell(1,1,limitr,upprice);
level:=level+1;
end
if low<=dnprice then begin
buy(1,1,limitr,dnprice);
level:=level-1;
end
if time=closetime(0) then
sell(1,holding,limitr,close);
end
if holding<0 then begin
upprice:=oo+(level+1)*grid*mindiff;
dnprice:=oo+(level-1)*grid*mindiff;
if low<=dnprice then begin
sellshort(1,1,limitr,dnprice);
level:=level-1;
end
if high>=upprice then begin
buyshort(1,1,limitr,upprice);
level:=level+1;
end
if time=closetime(0) then
sellshort(1,holding,limitr,close);
end
limitr 后边的参数就是限价的价格，改成oo就可以了。
input:grid(3,1,60,1);
variable:level=0;
dist:=barslast(date<>ref(date,1));
oo:=ref(open,dist);
if holding=0 then begin
dnprice:=oo-grid*mindiff;
if low<=dnprice then begin
buy(1,1,limitr,dnprice);
level:=-1;
end
end
if holding=0 then begin
upprice:=oo+grid*mindiff;
if high>=upprice then begin
buyshort(1,1,limitr,upprice);
level:=1;
end
end
if holding>0 then begin
upprice:=oo+(level+1)*grid*mindiff;
dnprice:=oo+(level-1)*grid*mindiff;
if high>=upprice then begin
sell(1,1,limitr,oo);
level:=level+1;
end
if low<=dnprice then begin
buy(1,1,limitr,dnprice);
level:=level-1;
end
if time=closetime(0) then
sell(1,holding,limitr,oo);
end
if holding<0 then begin
upprice:=oo+(level+1)*grid*mindiff;
dnprice:=oo+(level-1)*grid*mindiff;
if low<=dnprice then begin
sellshort(1,1,limitr,oo);
level:=level-1;
end
if high>=upprice then begin
buyshort(1,1,limitr,upprice);
level:=level+1;
end
if time=closetime(0) then
sellshort(1,holding,limitr,oo);
end
