MODIFY MY MQL5 FUNCTION TO RETURN LATEST ORDER TYPE

The code below correctly identifies the position type when there is only one trade opened, however if there are more than one position opened, the code does not return the latest position 

 modify it to identify the position type of the LATEST opened trade if there are more than one trade opened :

Example if 2 positions  are opened:

1 Buy  -  opened at 13:00

1 sell- Opened at 12:00

return 1 as this is the latest opened position which is a buy

double POSITTYPE()
  {

   double POSX=0;
   
   string   symbol;
   symbol=PositionGetSymbol(POSITION_SYMBOL);

    for(int i=PositionsTotal()-1;i>=0;i--)
     {
      if(PositionSelectByTicket(PositionGetTicket(i)) && 
            PositionGetString(POSITION_SYMBOL)==_Symbol && 
            PositionGetInteger(POSITION_MAGIC)==MagicNumber)
           {
            if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)
               POSX=1;
            if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
               POSX=2;
           
        }
     }
   return( POSX);
  }
