1.  

double HighestFrom0to5am = iHigh(NULL, PERIOD_H1,  iHighest(NULL, PERIOD_H1, MODE_HIGH, 5, TimeHour(TimeCurrent()) - 5) );

 from this you should get the idea of how to do the lowest . . .  

Note:  not tested . . .  please test properly.

2.   

OrderSelect(. . . . );

if(TimeDayOfYear(OrderOpenTime()) == TimeDayOfYear(TimeCurrent()))
   Print("Order was placed today ! ");

 this works unless your order is exactly a year or 2 years or 3 years, etc, old. 

  
double HighestFrom0to5am = iHigh(NULL, PERIOD_H1,  iHighest(NULL, PERIOD_H1, MODE_HIGH, 5, TimeHour(TimeCurrent()) - 5) );
why don't just use the IHighest ?? why need IHigh???i don't know what is the different

Look at the Documentation,  what does iHighest() return ?

if not i won't ask.thanks you very much

From the iHighest() documentation . . .  "Returns the shift of the maximum value over a specific number of periods depending on type."  it returns the shift ( bar number ),  not a price . . you want the price,  so you need to use iHigh  (or High[] )  to get the high of the bar number returned by iHighest.

The above codes makes use of the fact that you are on the H1 chart. Below works on any TF <= D1

not compiled, not tested

#define HR2400      86400           // 24 * 3600
datetime TimeOfDay(datetime when){  return( when % HR2400          );       }
datetime DateOfDay(datetime when){  return( when - TimeOfDay(when) );       }
//////
#define HR0500      18000
datetime OOT = OrderOpenTime(),
         now = TimeCurrent(),
         bod = DateOfDay(now),
         hr5 = bod + HR0500;
if (hr5 > now) .. // before 5AM. Next day? need to handle?
int     iBod = iBarShift(NULL, 0, bod),
        iHR5 = iBarShift(NULL, 0, hr5),
        iHH  = iHighest(NULL,0, MODE_HIGH, iBod - iHR5, iHR5+1); // Not including 5AM
double  HH5  = High[iHH];
bool    isTodaysTrade = DateOfDay(OOT) == bod;

not compiled, not tested
  
datetime OOT = OrderOpenTime()
bool    isTodaysTrade = DateOfDay(OOT) == bod;
i don't understand here

bool    isTodaysTrade = DateOfDay(OOT) == bod;
can explain please?

oh....! thanks!
  
#define HR2400      86400           // 24 * 3600
datetime TimeOfDay(datetime when){  return( when % HR2400          );       }
datetime DateOfDay(datetime when){  return( when - TimeOfDay(when) );       }

#define HR0500      18000
#define HR1200      43200

int start()
  {
//----
datetime now = TimeCurrent(),
         bod = DateOfDay(now)+ HR0500,
         hr5 = bod + HR1200;
if (hr5 > now) // before 5AM. Next day? need to handle?
{
int     iBod = iBarShift(NULL, 0, bod),
        iHR5 = iBarShift(NULL, 0, hr5),
        iHH  = iHighest(NULL,0, MODE_HIGH, iBod - iHR5, iHR5); 
double  HH5  = High[iHH];

}
Alert(HH5);
//----
   return(0);
  }
so, this is the code to get the 5:00A.m until 12:00P.m and get the highest Price...am i correct?
