Visualization of Objects created from current TF (<=) less than TF

Just set the display mask from the current TF and store. What's so hard?

int periodToDisplay(ENUM_TIMEFRAME period=PERIOD_CURRENT{
   if(period == PERIOD_CURRENT) period=_Period;
   const static int conv[9][2]={ PERIOD_M1, OBJECT_PERIOD_M1,
                                 PERIOD_M5, OBJECT_PERIOD_M5,
                                 ⋮
                                 PERIOD_MN1, OBJECT_PERIOD_MN1 }
   int obj_per = 0;
   for(int i=8; i >= 0; --i) if( PeriodSeconds(conv[i][0]) <= PeriodSeconds(period) )
      obj_per |= conv[i][1];
   return obj_per;
}

it won't be hard, would probably need to learn bit masking and Dynamic programming (was doing some research from your reply that what I came across), I have not used  such before. Thanks

I posted working code; OP was grateful. What did you do?

The following would work if you are looking at only the default TF(monthly, weekly ... 1H, 30M, 15M ... 1M)

Note: For all Timeframe you could change the code to set all bits of TF that are lower than the current period

int periodToDisplay(ENUM_TIMEFRAMES period=PERIOD_CURRENT)
   {
      //--- using a 9 by 2 to hold the values of the TF, and the bit value of the TF in question
      const static int conv[9][2] = {
                                    {PERIOD_M1, OBJ_PERIOD_M1},
                                    {PERIOD_M5, OBJ_PERIOD_M5},
                                    {PERIOD_M15, OBJ_PERIOD_M15},
                                    {PERIOD_M30, OBJ_PERIOD_M30},
                                    {PERIOD_H1, OBJ_PERIOD_H1},
                                    {PERIOD_H4, OBJ_PERIOD_H4},
                                    {PERIOD_D1, OBJ_PERIOD_D1},
                                    {PERIOD_W1, OBJ_PERIOD_W1},
                                    {PERIOD_MN1, OBJ_PERIOD_MN1}
                                    };
      //--- the value of the Timeframe when the object would be displayed
      int obj_per = 0;
      for (int i =8; i>=0; i--)
         //--- Check the TF if it is less or equal to the period in question
         if(conv[i][0] <= period)
            obj_per |= conv[i][1];        // if it true, add the value of TF to obj_per                           
      return obj_per;                                 
   }

Hope it helps, just another option ( I prefer smaller codes)

int periodToDisplay(string &name, ENUM_TIMEFRAMES &period)
   {
     //---  Obj_Period to be returned
     long obj_per = 1;
      //--- Rather than using PERIOD_M1, you could use "1", I used that to make more readable
      for (int i = period; i>= PERIOD_M1; i/=2)
         obj_per |= (obj_per << 1);                                 
      return obj_per;                                 
   }

Note: You will need to do one or two modifications in the above code, to get the results you would be after, I could add it, but where the fun in that, post your modification lets see... cheers

Yeah, sometimes it feels that way, but imagine if he didn't or no one responded at all, he is not obliged to respond, no one is, what ever the reason someone decides to respond, it is cool to be thankful and move on, cause at the end of the day, you won't be asking for it if you don't need it, that is how I see it
