請教：如何在下面這個日內交易模型(五分鐘周期)加上提前5秒下單  。

T1:=TIME>090000 AND TIME <145000;
pkkd:=cross(c,ma(c,5)) and t1;

pdkk:=cross(ma(c,5),c) and t1;

if pkkd then
   begin
   sellshort(holding < 0, 1, limitr,open);
   buy(holding = 0, 1, limitr,c+5*mindiff);
   end

if pdkk then
   begin
   sell(holding > 0, 1, limitr,open);
   buyshort(holding = 0, 1, limitr,c-5*mindiff);
   end

T1:=TIME>090000 AND TIME <145000;

nn:=timetot0(time)-timetot0(dynainfo(207));
pkkd:=cross(c,ma(c,5)) and t1;

pdkk:=cross(ma(c,5),c) and t1;

if pkkd  and nn<=5 and islastbar  or (pkkd and not(islastbar))  then
   begin
   sellshort(holding < 0, 1, limitr,open);
   buy(holding = 0, 1, limitr,c+5*mindiff);
   end

if pdkk  and nn<=5 and islastbar  or (pdkk and not(islastbar)) then
   begin
   sell(holding > 0, 1, limitr,open);
   buyshort(holding = 0, 1, limitr,c-5*mindiff);
   end

timetot0(time)： 括號中的時間距離當日0點的秒數。

括號中的time是k線時間，例如5分鐘周期第一根k線的time是090500 轉換成秒，返回結果是32700秒。
