How to make a good example of how to use the code in your new e-commerce platform - Trading stocks, futures, options and other exchange instruments

Thank you. Added your option as a parallel check. Now it's just a matter of catching the right moment.

I'm 100% sure it will work!

Because you didn't fill the structure correctly (not just the fields, but the values as well).

Strange that the compiler didn't "swear".

You:

MqlTradeRequest.action = TRADE_ACTION_DEAL;

It needs to:

MtRequest.action = TRADE_ACTION_DEAL;

But no! The code in my message is not from the Expert Advisor, it is a corrected fragment of logs where debugging information is written from the Expert Advisor. My bad, my mistake.)

The EA itself fills in the structure as required, but the result of the check is different. It either calculates the margin correctly or gives some nonsense like in the example.

Here is a fragment from the live site

   MqlTradeRequest MtRequest = {0}; 

   switch(OrderType)
   {
      case ORDER_TYPE_BUY:         
         MtRequest.price     = CurrentTick.ask;         
         break;

      case ORDER_TYPE_SELL:         
         MtRequest.price     = CurrentTick.bid;
         break;

      default:
         LogFile.Log(LOG_PRINT,__FUNCTION__," error: Invalid OrderType");
         return(false);
   }

   MtRequest.tp        = 0.0;
   MtRequest.sl        = 0.0;
   MtRequest.action    = TRADE_ACTION_DEAL;
   MtRequest.magic     = 0;
   MtRequest.symbol    = strSymbol;
   MtRequest.volume    = dblLots;
   MtRequest.deviation = Config.Deviation;
   MtRequest.type      = OrderType;
   MtRequest.type_filling = Config.OrdersFillingType;

Make it so:

   MqlTradeRequest MtRequest = {0}; 
   MqlTradeRequest MtResult = {0}; 

   switch(OrderType)
   {
      case ORDER_TYPE_BUY:         
         MtRequest.price     = CurrentTick.ask;         
         break;

      case ORDER_TYPE_SELL:         
         MtRequest.price     = CurrentTick.bid;
         break;

      default:
         LogFile.Log(LOG_PRINT,__FUNCTION__," error: Invalid OrderType");
         return(false);
   }

   MtRequest.action    = TRADE_ACTION_DEAL;
   MtRequest.magic     = 77777777777777;
   MtRequest.symbol    = strSymbol;
   MtRequest.volume    = dblLots;
   MtRequest.type      = OrderType;
   MtRequest.type_filling = Config.OrdersFillingType;
   MtRequest.type_time = ORDER_TIME_DAY;

Here's another moment in the log:

I pass the same structure to OrderSend() and everything opens perfectly!

By the way, build 1194.

Selling Si-12.15, 2 lots. GO for 1 contract is 5090 rubles. A trade should have the QR 5090*2 = 10180 RUB. But the function returns 172148.68 RUB, which equals 172148.68 / 5090 = 33.82 contracts!

What a miracle...

What wonders...

1. I gave you a sample of how to properly fill out the structure, and you ignore this advice.

Then why are you asking?

2. 1194 build is not compatible with current servers (Renat mentioned this. Use build 1159 for now).

3. I don't use OrderCheck() at all, I check the funds myself.

//+------------------------------------------------------------------+

bool CheckMoney( const string a_symbol, const long volume )
{
  if ( volume <= 0 )
  {
    Print( "Check Money: Объём лота указан не правильно!" );
    retutn ( false );
  } 
//---
  double a_go = SymbolInfoDouble( a_symbol, SYMBOL_MARGIN_INITIAL ) * double( volume);
  double free_margin = ( AccountInfoDouble( ACCOUNT_FREEMARGIN ) / 100 ) * 90; //90% от свободных средств
//---  
  if ( a_go <= free_margin )
  {
    return( true );
  }
  Print( "Check Money: Не достаточно средств!" );
  return( false );

2. Oh, man! I didn't know that.

3. I did the same thing. And the function is almost exactly the same, except 90% (good idea, by the way)

I raised this question because my function (similar to yours) checks CS and allows to open position, while standard OrderCheck() sometimes fails.

This probably refers to point 2.

So use all your own on FORTS - it's much more correct :)

That's how you end up doing it! Tempted somewhere to use someone else's code or library, in order to save time on writing a "wheel" or test some idea.

But in the end you have to spend a week on catching errors and defects of other developers. In the end everything is rewritten so that there is no trace of other people's code.

Hello!

Futures glues appeared in the test window, which in itself is very pleasing, however, when trying to match the glue with the contract, I found that there are no trades on the glue at all - everything is fine on the contracts - there are quite a lot of trades. I checked on four instruments Si,RTS,GAZR,SBRF and the period 01.01.2015 -24.10.2015.
