Hi All,

Is it passble to specify which Symbol the code can look in? for ex: I need it to look in "AUDCAD" Pair.

#property indicator_chart_window

   double prevbid=0;
   
//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int OnInit()
  {

   for (int i=0;i<ObjectsTotal();i++) 
   {
      string name=ObjectName(i);
      if ((ObjectType(name)==OBJ_TREND) || (ObjectType(name)==OBJ_HLINE)) 
      {
         ObjectSet(name,OBJPROP_PRICE3,0);
      }
   }

//---
   return(INIT_SUCCEEDED);
  }

//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {
//---

   double value,prevvalue;
//----
   for (int i=0;i<ObjectsTotal();i++) {
      string name=ObjectName(i);
      if ((ObjectType(name)==OBJ_TREND) || (ObjectType(name)==OBJ_HLINE)) 
         {
         if (ObjectType(name)==OBJ_TREND) {value=ObjectGetValueByShift(name,0);} 
            else { value=ObjectGet(name,OBJPROP_PRICE1); }
            
         prevvalue=ObjectGet(name,OBJPROP_PRICE3);
         if ((prevbid!=0) && (prevvalue!=0))
            if (value_to_toggle && (((Bid>value) && (prevbid<=prevvalue )) || ((Bid<value) && (prevbid>=prevvalue))))
            
            
            {
               Alert("Trend Line Crossed    ", Symbol(), ", ", TimeToStr(CurTime(),TIME_DATE | TIME_MINUTES));

              // PlaySound("alert.wav");
            }            
         ObjectSet(name,OBJPROP_PRICE3,value);
      }
   }
   prevbid=Bid;


//--- return value of prev_calculated for next call
   return(rates_total);
  }

  1. Do not trade multiple currencies
    • You can't use any predefined variables, can't use the tester, must poll (not OnTick,) and usually other problems.
    • Code it to trade the chart pair only. Look at the others if you must.
    • Then put it on other charts to trade the other pairs. Done.

  2. if ((ObjectType(name)==OBJ_TREND) || (ObjectType(name)==OBJ_HLINE)) 
          {
             ObjectSet(name,OBJPROP_PRICE3,0);
    Why are you setting price three? A Trend line only has two and a horizontal line only has one. Have you verified that that works?
  3. Objects are only on the current chart. You can't read others.
