You need to fix your code.

[Hossein Zandi]

your EA must be able to check the correct volume of the orders based on the currency pairs and broker conditions before sending an order.

what function shall I write to check broke conditions of trading operations ? 

[Marius Ovidiu Sunzuiana]

@Eleni Anna Branou I don t know what to fix because I don t understand the return message... in strategy tester works but if test for market upload does not work

[Sergey Golubev]

The checks a trading robot must pass before publication in the Market 

Before making a trade request for placing a pending order by a symbol, you should check the limitation on the total volume of open position and pending orders on one symbol - SYMBOL_VOLUME_LIMIT. If there is no limitation, then the volume of a pending order cannot exceed the maximum allowed volume that can be received using the SymbolInfoDouble() volume.

double max_volume=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_LIMIT);
if(max_volume==0) volume=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_MAX);

----------------

https://www.mql5.com/ru/docs/constants/environment_state/marketinfoconstants#enum_symbol_info_integer 

SYMBOL_VOLUME_LIMIT

Maximum allowed aggregate volume of an open position and pending orders in one direction (buy or sell) for the symbol. For example, with the limitation of 5 lots, you can have an open buy position with the volume of 5 lots and place a pending order Sell Limit with the volume of 5 lots. But in this case you cannot place a Buy Limit pending order (since the total volume in one direction will exceed the limitation) or place Sell Limit with the volume more than 5 lots.

and I found the thread in Russian forum:

MQL5: Validation :-( I have already broken my mind over the search for what it is and how it is solved. 

I am not a coder but there are two post from this thread (hope it helps):

I decided.

 //в функции до открытия ордера.

double max_volume= SymbolInfoDouble (m_name, SYMBOL_VOLUME_LIMIT );

       double current_lots=getAllVolume();

       if (max_volume> 0 && max_volume-current_lots-dlot<= 0 )
        {
         //PrintFormat("%.2f - %.2f",max_volume , dlot);
         return 0 ;
        }
//...
//функция подсчета объема
double getAllVolume()
     {
       int itotal= PositionsTotal ();
       ulong uticket=- 1 ;
       double dVolume= 0 ;

       for ( int i=itotal- 1 ;i>= 0 ;i--)
        {
         if (!(uticket= PositionGetTicket (i))) continue ;

         if ( PositionGetString ( POSITION_SYMBOL )==m_symbol.Name())
            dVolume+= PositionGetDouble ( POSITION_VOLUME );
        }

      itotal= OrdersTotal ();

       for ( int i=itotal- 1 ;i>= 0 ;i--)
        {
         if (!(uticket= OrderGetTicket (i))) continue ;

         if ( OrderGetString ( ORDER_SYMBOL )==m_symbol.Name())
            dVolume+= OrderGetDouble ( ORDER_VOLUME_CURRENT );
        }

       return dVolume;
     }

After that, the product successfully passed the test.

Yes, by the way, consider when calculating that SYMBOL_VOLUME_LIMIT can be equal to "0.0".

In order not to fall for verification:

 if (check_volume > SymbolInfoDouble (Symbol(), SYMBOL_VOLUME_LIMIT ))
   return ;

OK I will review thanks guys
