... Parameter passed as reference, variable expected

[ferox875]

Hello, sorry my noob question but is the following:

in my LimitTakeProfit.mqh file, when I compile receive the following errors

'CSymbolInfo' - parameter passed as reference, variable expected LimitTakeProfit.mqh 55 56

'CArrayLong' - parameter passed as reference, variable expected LimitTakeProfit.mqh 56 56

'CArrayDouble' - parameter passed as reference, variable expected LimitTakeProfit.mqh 57 56

here is the variable declaration:

private:

   static CSymbolInfo       c_Symbol;

   static CArrayLong        i_TakeProfit; //fixed take profit

   static CArrayDouble      d_TakeProfit; //percent to close at take profit

  

here are the lines that create compilation error:

CSymbolInfo    CLimitTakeProfit::c_Symbol       =  new CSymbolInfo();

CArrayLong     CLimitTakeProfit::i_TakeProfit   =  new CArrayLong();

CArrayDouble   CLimitTakeProfit::d_TakeProfit   =  new CArrayDouble();

I understand that should be a very simple solution, but searching didn't found anything specific

Thanks in advance, best regards

1. These are objects.

      static CSymbolInfo       c_Symbol;
      static CArrayLong        i_TakeProfit; //fixed take profit
      static CArrayDouble      d_TakeProfit; //percent to close at take profit

2. You are creating handles to objects.

   CSymbolInfo    CLimitTakeProfit::c_Symbol       =  new CSymbolInfo();
   CArrayLong     CLimitTakeProfit::i_TakeProfit   =  new CArrayLong();
   CArrayDouble   CLimitTakeProfit::d_TakeProfit   =  new CArrayDouble();

3. Just create the objects with whatever parameters are required.

   CSymbolInfo    CLimitTakeProfit::c_Symbol(…);
   CArrayLong     CLimitTakeProfit::i_TakeProfit(…);
   CArrayDouble   CLimitTakeProfit::d_TakeProfit(…);
