Is it different to run Expert in Real Account and Demo Account?

New comment
 

Hi

I wrote the Expert for Auto trading.(mql4) It goes very well in demo account.

I tested multi times, without any problem.

BUT when i want to use it on real account, it does not working... :(
WHY?

I checked everything : SL,Tp, Slippage ,..... .

All parameters,All numbers , and ...... are true. But i do not know why is not working on Real Account.

 what is wrong? slippage? Ask? bid?   

which one??

Can anyone help me?

Here the code :    

 int buyy;
 int OnInit()
  {         
       buyy=OrderSend(Symbol(),OP_BUY,0.01,Ask,2,Ask-5,0,"Buy",001,0,clrGreen);
       
       Comment("buy: ",buyy)
   return(INIT_SUCCEEDED);
  }

Hello, did you try to Optimize your lot size maybe? or you can check on the expert message, maybe something wrong there
  
       buyy=OrderSend(Symbol(),OP_BUY,0.01,Ask,2,Ask-5,0,"Buy",001,0,clrGreen);
  1. Check your return codes, and report your errors.

    Don't look at GLE/LE unless you have an error. Don't just silence the compiler, it is trying to help you.

  2. You buy at the Ask and sell at the Bid.
    1. Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using the Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?

    2. Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger at a specific Bid price, add the average spread.

    3. The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
      Most brokers with variable spread widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY (OANDA) shows average spread = 26 points, but average maximum spread = 134.

  3. You can't move stops (or pending prices) closer to the market than the minimum: MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).

    On some ECN type brokers the value might be zero (broker doesn't know.) Use a minimum of two (2) PIPs.

  4. What is Ask? On EURUSD it would be 1.1234º and subtracting 5 would be negative. № 1, № 2, № 3.
