How to know if trading for a given symbol is allowed or not?

Hi guys. This is my code but looks like trading is not possible for my symbol. Thoughts ?

ZeroMemory(mrequest);

mrequest.action = TRADE_ACTION_DEAL;                                  // immediate order execution

mrequest.price = NormalizeDouble(latest_price.ask,_Digits);           // latest ask price

mrequest.sl = NormalizeDouble(latest_price.ask - STP*_Point,_Digits); // Stop Loss

mrequest.tp = NormalizeDouble(latest_price.ask + TKP*_Point,_Digits); // Take Profit

mrequest.symbol = _Symbol;                                            // currency pair

mrequest.volume = Lot;                                                 // number of lots to trade

mrequest.magic = EA_Magic;                                             // Order Magic Number

mrequest.type = ORDER_TYPE_BUY;                                        // Buy Order

mrequest.type_filling = ORDER_FILLING_FOK;                             // Order execution type

 mrequest.deviation=100;                                                // Deviation from current price

//--- send order

OrderSend(mrequest,mresult);

The error message looks like this:

[Unsupported filing mode] -error: 4756


Now I've also experimented with 

mrequest.type_filling = ORDER_FILLING_IOC; 

and

mrequest.type_filling = ORDER_FILLING_RETURN;

The problem persists.

Also, I added the following:

int FillingMode=(int)SymbolInfoInteger(_Symbol,SYMBOL_FILLING_MODE);

      

      Comment (

           "Filling Mode: ",FillingMode,

         "\nSymbol      : ", SymbolInfoString(_Symbol, SYMBOL_DESCRIPTION),         

         "\nAccount Company: ", AccountInfoString(ACCOUNT_COMPANY),

         "\nAccount Server : ", AccountInfoString(ACCOUNT_SERVER));

It prints out:

Filling Mode: 0

Symbol: EUR/USD

Account Company: AMP Global Clearing LLC

Account Server: AMPGlobalClearing-Demo-CQG

That is a Futures broker. In that broker, the Forex symbols only exist for informative purposes, but it is not allowed to trade them. Therefore, you can not trade EURUSD, instead you can trade the Future (Euro Fx (Globex)), with Expiration in December 2017 (symbol called ‘EU6Z7’) or with Expiration in March 2018 (symbol called ‘EU6H8’) ').

Before sending a trade request, you should check if it is an allowed to trade symbol:

  ENUM_SYMBOL_TRADE_MODE trade_mode = (ENUM_SYMBOL_TRADE_MODE)SymbolInfoInteger(_Symbol, SYMBOL_TRADE_MODE);
  
   //  You can Print the result if you want:  
   //  Print("Symbol Trade Mode = ", EnumToString(trade_mode));
   
   if(trade_mode == SYMBOL_TRADE_MODE_FULL)
   {
      //  Your request
   }

Check if filling mode is allowed for the symbol. My broker claims IOC is supported. But when I checked, only FOK is allowed. I ran this on both demo and live accounts. I got the same results.

IF you want FOK, use mrequest.action = TRADE_ACTION_PENDING;

 uint filling=(uint)SymbolInfoInteger(_Symbol,SYMBOL_FILLING_MODE);
  
  if((filling&SYMBOL_FILLING_FOK)==SYMBOL_FILLING_FOK)
   {
    Print("ORDER_FILLING_FOK allowed");
   }
  if((filling&SYMBOL_FILLING_IOC)==SYMBOL_FILLING_IOC)
   {
    Print("ORDER_FILLING_IOC allowed");
   }

The problem in this case is that no filling mode is allowed for Forex symbols in that broker. It is a Futures broker and therefore, it is only allowed to trade in Futures. The Forex symbols have a Trade Mode = SYMBOL_TRADE_MODE_DISABLED, as I mentioned to bpedrazzic. You should check if it is allowed to trade that symbol before checking the filling mode. Regards.

I am having a similar issue, I am new, maybe they are something that I am doing wrong but I looked all previous threads about the invalid filling mode bug without success…

I can trade on the symbol with TRADE_ACTION_PENDING for Buy Limit/Stop/ or Sell Limit/Stop without issue but if I want just to BUY or SELL with TRADE_ACTION_DEAL I always got the invalid filling bug.

here some of my logs before doing trade, init part…

I use the GetFilling function that someone posted on this forum, I also tried all the filling mode without any success…

someone know what could be the issue? if I do PENDING buy/sell limit no problem…

// true - not for trade by market-orders
bool IsBadFilling( const string Symb )
{
  return(!(SymbolInfoInteger(_Symbol, SYMBOL_FILLING_MODE) & (SYMBOL_FILLING_IOC | SYMBOL_FILLING_FOK)));
}

void OnTick()
{
  if (IsBadFilling(_Symbol))
  {
    Print("Change symbol " + _Symbol + " or server " + AccountInfoString(ACCOUNT_SERVER) + " for trade by market!");
    
    ExpertRemove();    
  }
}

Result

If I use this function, well the corrected one that is not buggy (parameter is useless) :slight_smile:

bool CMMTrade::IsBadFilling(const string symbol) const

{

return !(SymbolInfoInteger(symbol, SYMBOL_FILLING_MODE) & (SYMBOL_FILLING_IOC | SYMBOL_FILLING_FOK));

}

None of the symbol is supposed to work on that server… why PENDING action work?

If I need to test BUY and SELL what DEMO server should I use?

Also If I try to make a BUY or SELL on pending mode, well no error but nothing append, no error, no log, nothing, its why I was trying to use DEAL since all example outthere use that…

This tell me that I can trade FULL ACCESS on that server.

If I cannot, what server should I use?

Because your response and tell nothing but just CHANGE SERVER … so what server should I use to test? its what I asked previously

#11 
FIBOGroup-MT5 Server
ICMarkets-Demo
FXOpen-MT5
MetaQuotes-Demo
...
#12
