tt:=not(time>210000 and time<=230000);

hh:valuewhen(time=230000,hhv(h,2));

ll:valuewhen(time=230000,llv(l,2));

if tt and h>hh and holding=0 and bj=0 then begin

    buy(holding=0,1,marketr);

    bj:=1;

end

if tt and l<ll and holding=0 and bj=0 then begin

    buyshort(holding=0,1,marketr);

    bj:=1;

end

if holding>0 and l<ll then sell(1,0,marketr);

if holding<0 and h>hh then sellshort(1,0,marketr);

if time=220000 then begin

   sell(1,0,marketr);

   sellshort(1,0,marketr);
