主题：止损的的价位作为下一次交易信号的起点 ？

我想把oo定义成为    oo = oo-(n+1)*grid*mindiff或者oo = oo+(n+1)*grid*mindiff; 就是止损后的价位重新作为一个起点

重新画区间，请问大神怎么定义oo 呢？？？？

input:grid(70,1,600,1);
variable:level=0;
n: = 10;
保证金比率： = 0.1;
SS: = ASSET/n/CLOSE/MULTIPLIER/保证金比率;
VARIABLE : oo = 3000;

if holding=0 and c >oo then begin        //初始化开多

dnprice:=oo-grid*mindiff;

if low<=dnprice then begin
buy(1,SS,limitr,dnprice);
level:=-1;

end
end
if holding=0 and c<oo  then begin       //初始化开空
upprice:=oo+grid*mindiff;

if high>=upprice then begin
buyshort(1,SS,limitr,upprice);
level:=1;

end
end
if holding>0 and level <n  then begin     //加多
upprice:=oo+(level+1)*grid*mindiff;
dnprice:=oo+(level-1)*grid*mindiff;

if high>=upprice then begin
sell(1,SS,limitr,upprice);
level:=level+1;
end
if low<=dnprice then begin
buy(1,SS,limitr,dnprice);
level:=level-1;
end
end

if holding<0 and level <n  then begin         //加空
upprice:=oo+(level+1)*grid*mindiff;
dnprice:=oo+(level-1)*grid*mindiff;

if low<=dnprice then begin
sellshort(1,SS,limitr,dnprice);
level:=level-1;

end

if high>=upprice then begin
buyshort(1,SS,limitr,upprice);
level:=level+1;
end
end

if holding >0 and l <oo then begin      //多 切换
sell(1,holding,limitr,oo);
end
if holding <0 and h> oo then begin    //空  切换
sellshort(1,holding,limitr,oo);
end
if holding >0 and h >oo+(n+1)*grid*mindiff then begin    //多全平
  oo = oo+(n+1)*grid*mindiff;
 sellshort(1,holding,limitr,close);
 end
 if holding <0 and l >oo-(n+1)*grid*mindiff then begin   //空全平
 
 oo = oo-(n+1)*grid*mindiff;
 sell(1,holding,limitr,close);
 end
