You implement method chaining to a newly created object

CPosition* CPosition::operator[](const int indexPar)
{
   if(CheckPointer(this.mObject) == POINTER_INVALID)this.mObject = new CPosition(this.GroupSymbol,this.GroupMagicNumber,this.Group);
   long ticketTemp = this.SelectByIndex(indexPar);
   return this.mObject;
} 

The above allows code like this

   //-- Modify the position using quick access feature
   position[0].Modify(50,50,SLTP_PIPS);

But I suggest that you better re-use the existing object and return a pointer to self.

CPosition* CPosition::operator[](const int indexPar)
{
   long ticketTemp = this.SelectByIndex(indexPar);
   return GetPointer(this);
}

You have right. I'll make an update. 

If you have any other robust solutions and implementations please feel free to share.
Also, if you want to be a contributor on GitHub just let me know.
The MQL_Easy belongs to everyone who find it useful. 

Thank you.

This error produced by the line of code 

position.SelectByIndex(0)// it didn't manage to select the order for some reason 

I would like to know what type of account you use (hedging or netting).
I will check it deeply when the markets is open.

Thank you.

Hi,

I couldn't replicate the issue with metatrader MT5 terminal except from the FXTM terminal. 
The issue occurs because of the lack of execution trade of FXTM demo server. If you copy paste the delay function between the code which execute the trade and the selection of position, it resolves the issue. 

//-- Create a trade Position BUY 
   ENUM_TYPE_POSITION type = TYPE_POSITION_BUY;
   double volume = 0.10;
   double stopLoss = 20;
   double takeProfit = 20;    
   execute.Position(type,volume,stopLoss,takeProfit,SLTP_PIPS);
   //-- delay for visual purposes and slow brokers
   Sleep(2000);
   //-- Collect Information about the trade
   if(position.SelectByIndex(0)){
      long ticket       = position.GetTicket();
      double openPrice  = position.GetPriceOpen();  
      Print("#Ticket: "+(string)ticket+", OpenPrice: "+(string)openPrice);    
   }   

I will update the script example and i will insert another small delay in order to deal with the slow execution of brokers. 

Thank you!

Unfortunately, then your library is of little use, since it is impossible to write a trading code equally on both platforms.

Try using your library to write this trade MT4-logic for MT5.

Hi,

As i show you, there is a delay on FXTM demo broker which produce the issue above. It is not the library fault. That issue can occur with pure MQL language.
The script example works on both platforms. So it is possible. 
The MQL_Easy's goal is not only for cross platform compatibility but to encapsulate the complexity and make it easy to create MQL applications.
Of course the MT5 has more features than MT4 and in the future it will have even more. This is why it is designed in such a way that
you can scale the MT5 part without the MT4. 
If you have a specific code or example that you think it will suits better, just let me know.

Thank you.

Here I immediately found two topics on this issue.

Hi,

I will create a solution for slow brokers based on the links you show. 

Thank you.
