U should check the buffer value. To change the line color u need to have 2 buffers lets say that buffer 1 is blue buffer 2 is red.
Buffer 1 is defined as buffer 0 in init function, and buffer 2 is defined as buffer 1 in init SetIndexBuffer(0,buffer1);
So the first buffer covers second, if the first buffer will be empty - u will see the other color.

babarmughal,

I've noticed that the TriggerLines indicator has 4 buffers!
1- when the color is BLUE the 4 of them have values!
2- when the color is RED the buffers 0 and 1 only have values!

So the code of the EA should be something like that:

double signal = iCustom(NULL,0,"triggerlines",Rperiod,LSMA_Period,2,0);
if (signal != EMPTY_VALUE) <--- Color is BLUE
if (signal == EMPTY_VALUE) <--- Color is RED

Give it a try!

Hi CG,

I have tried the code works fine but got 1 question...where there are more than 1 trades infact there should be only 1 trade when the colour of line has been changed..the areas are in the blue circle

Thanks

You have to use code like this:

PHP Code:


			
bool isNewSymbol(string current_symbol)
  {
   //loop through all the opened order and compare the symbols
   int total  = OrdersTotal();
   for(int cnt = 0 ; cnt < total ; cnt++)
   {
      OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
      string selected_symbol = OrderSymbol();
      if (current_symbol == selected_symbol && OrderMagicNumber()==MagicNumber)
      return (False);
    }
    return (True);
}
  
 if(OrdersTotal() < 1 || isNewSymbol(Symbol())) 
     {
       if(BuyCondition) //<-- BUY condition
         {
           //<-- Open BUY order
            return(0);
         }
         if(SellCondition) //<-- SELL condition
         {
            //<-- Open SELL order
            return(0);
         }
         return(0);
     }

    }

    return (True);

}

  

 if(OrdersTotal() < 1 || isNewSymbol(Symbol())) 

     {

       if(BuyCondition) //<-- BUY condition

         {
