how to find high/low for 2 min timeframe

[andream1977]

hi

 

i dont understand how to find the high and the low of the last 2 minute candle

i use this code:

 

void OnTimer() 
   {
   
   datetime thisTime = TimeLocal();
   MqlDateTime tm;
   TimeToStruct(thisTime,tm);
   currentHour = tm.hour;
   currentMinutes = tm.min;
   int currentSecond = tm.sec;
   long div = currentMinutes % 2;

   if (div == 0)
      {
      if (currentSecond == 0)
         {
        
         double highPriceArray[],lowPriceArray[];
         
         CopyHigh(
            Symbol(),     
            PERIOD_M2,       
            thisTime,      
            1,           
            highPriceArray     
         );
         CopyLow(
            Symbol(),     
            PERIOD_M2,       
            thisTime,      
            1,           
            lowPriceArray     
         );

         Print("high: ",highPriceArray[0],"low: ",lowPriceArray[0]);


   }
   

}

 my code, print price different from the price of my mt5 chart, where is my error?

Your chart is at broker server time, use TimeCurrent() not TimeLocal().

it's work with this change,  to get the info of previous 2 min candle i need to take last 2 candle:

 datetime thisTime = TimeCurrent();


         CopyHigh(
            Symbol(),     
            PERIOD_M2,       
            thisTime,      
            2,           <-- i have to request the last two candle if i want the previous candle
            highPriceArray     
         );

 then info about prev candle: 

Print("high: ",highPriceArray[1],"low: ",lowPriceArray[1]);

instead if i want the info about current candle: 

Print("high: ",highPriceArray[0],"low: ",lowPriceArray[0]);

 right?

Only if your arrays are indexed as series :

ArraySetAsSeries(highPriceArray,true);
ArraySetAsSeries(lowPriceArray,true);
