Error 4756 (ERR_TRADE_SEND_FAILED) using "Instant Execution" requests
Everything works fine now without changing anything, I guess the demo servers had some issues.
request.type_filling = ORDER_FILLING_FOK
have a try ,change the ORDER_FILLING_FOK.because the symbol it's own ORDER_FILLING mode.
i'm not sure it's changeable.
i'm get a prolem when a use the CTrade PositionOpen.some symbol can but some not with no error.now ,it's ok after the FILLING Mode changed.

Hello
Good time
I wrote the following code in mql5, when I test it, it gives error 4756
Please guide me

Hi,
I'm having the same issue. The EA worked fine in the strategy tester, but now that i'm trying to run it in real time in the demo account i'm receiving error 4756. Does anyone knows why is this happening?

I'm trying to buy and sell at market value with the "Instant Execution" method (see here https://www.mql5.com/en/docs/constants/structures/mqltraderequest).
I have filled the required properties of the request, but OrderCheck returns error code 4756, from the docs:
ERR_TRADE_SEND_FAILED
4756
Trade request sending failed
I googled the error but couldn't find anything. I am using a demo acount and the strategy tester so there is no broker involved.
Note 1: The first buy and the first sell work.
Note 2: If I remove the OrderCheck() calls, I all buy orders work successfully but sells still fail, it' doesn't make any sense.
Below the code :
void OnTimer()
{
MqlTick curTick;
if(!SymbolInfoTick(Symbol(), curTick)) return;
if(...){ //true when I need to buy, false when I need to sell
Request request;
request.action = TRADE_ACTION_DEAL;
request.symbol = Symbol();
request.volume = 1;
request.price = curTick.ask;
request.sl = 0;
request.tp = 0;
request.deviation = 0;
request.type = ORDER_TYPE_BUY;
request.type_filling = ORDER_FILLING_FOK;
MqlTradeCheckResult checkResult;
bool success = OrderCheck(request, checkResult);
if(!success) Print("OrderCheck failed error: ", GetLastError());
MqlTradeResult tradeResult;
bool successTrade = OrderSend(request, tradeResult);
if(!successTrade) Print("OrderSend (buy) failed error: ", GetLastError());
}else{
MqlTradeRequest request;
request.action = TRADE_ACTION_DEAL;
request.symbol = Symbol();
request.volume = 1;
request.price = curTick.bid;
request.sl = 0;
request.tp = 0;
request.deviation = 0;
request.type = ORDER_TYPE_SELL;
request.type_filling = ORDER_FILLING_FOK;
MqlTradeCheckResult checkResult;
bool success = OrderCheck(request, checkResult);
if(!success)Print("OrderCheck failed error: ", GetLastError());
MqlTradeResult tradeResult;
bool successTrade = OrderSend(request, tradeResult);
if(!successTrade)Print("OrderSend (sell) failed error: ", GetLastError());
}
}
I am properly checking that trading is allowed :
int OnInit()
{
Print("SYMBOL_TRADE_EXEMODE= ", SymbolInfoInteger(Symbol(), SYMBOL_TRADE_EXEMODE));
Check_SYMBOL_ORDER_MODE(Symbol());
if(!TerminalInfoInteger(TERMINAL_TRADE_ALLOWED))
Alert("Automated trading is not allowed in the terminal settings!");
if(!MQLInfoInteger(MQL_TRADE_ALLOWED))
Alert("Automated trading is forbidden in the program settings for ",__FILE__);
if(!AccountInfoInteger(ACCOUNT_TRADE_EXPERT))
Alert("Automated trading is forbidden for the account ",AccountInfoInteger(ACCOUNT_LOGIN)," at the trade server side");
if(!AccountInfoInteger(ACCOUNT_TRADE_ALLOWED))
Comment("Trading is forbidden for the account ",AccountInfoInteger(ACCOUNT_LOGIN),
".\n Perhaps an investor password has been used to connect to the trading account.",
"\n Check the terminal journal for the following entry:",
"\n\'",AccountInfoInteger(ACCOUNT_LOGIN),"\': trading has been disabled - investor mode.");
EventSetTimer(10);//10sec
return(INIT_SUCCEEDED);
}
