How to find day's first candle's HIGH, LOW in current Time frame

Question

I am new to MT4, know little basic programming for MQL4. I am trading in UTC+5:30 in Indian Stocks. I just want a small piece of code to get today's First candles HIGH and LOW in current TimeFrame. Our trading starts at 9:15 AM IST and ends at 3:30 PM IST.

e.g. if I select PERIOD_M15 (15 min chart) then I need to have day's first candle (i.e. from 9:15AM to 9:30AM) HIGH and LOW.

thanks in advance.

welcome to SOF!

you need input parameters (time of the day start):

input int InpTimeStartHour=9; input int InpTimeStartMinute=15; this can be as a one string but for simplicity such fields

bool getHighLowFistCandle(double &high,double &low){
   //check if first candle (zero-current) is after 9:15
   datetime lastCandle=iTime(Symbol(),0,1);
   if(TimeHour(lastCandle)<InpTimeStartHour || 
      (TimeHour(lastCandle)==InpTimeStartHour && TimeMinute(lastCandle)<InpTimeStartMinute){
      return(false);
   }
   //looking for that time candle starting from day start
   datetime todayStart=iTime(Symbol(),PERIOD_D1,0);
   int shift=iBarShift(Symbol(),0,todayStart);
   for(int i=shift;i>0;i--){
      datetime iCandleTime=iTime(Symbol(),0,i);
      if(TimeHour(iCandleTime)==InpTimeStartHour &&
         TimeMinute(iCandleTime)==InpTimeStartMinute){
          high=iHigh(Symbol(),0,i);
          low=iLow(Symbol(),0,i);
          return(true);
      }
   }
  return(false);
}
