Stop order within specified time period

I used the following to generate a stop order within time>=0916 and time<=1615,I tried the following programme in backtesting and found that stop order will not be generated outside the time period. however I still see stop order generated in IB screen after 1615 in real trade, is there any problem with the following programme?

if date=trade_date then begin

if time>=0916 and time<=1615 then begin

if ((mp_s[1]=0 and mp_s>0) or
(mp_s[1]=0 and mp_s<0) or
(mp_s[1]>0 and mp_s=0) or
(mp_s[1]<0 and mp_s=0) or
(mp_s[1]>0 and mp_s<0) or
(mp_s[1]<0 and mp_s>0)) then traded=traded+1;

If traded=0 and action = 1 then
buy 2 contract next bar at Tri stop;

If traded=0 and action = 2 then
sellshort 2 contract next bar at Tri stop;

end;
end;

Hello dingmanhoe123,

Even in backtesting the following code can generate the order after 1615 as "next bar" order command is used and the condition is "if time>=0916 and time<=1615".
