Warning of OrderSelect(), OrderSend()
What are Function return values ? How do I use them ?
- www.mql5.com
I see many, many people posting code and asking questions which can usually be answered by simply checking the return values from a few Functions a...
Thankyou, I really appreciate your reply.
I understand that it's about the return value, which for MT5 should be "bool"
Still I don't know what is the proper solution for this code
for the OrderSend()
do
{
if(pType == ORDER_TYPE_BUY) request.price = SymbolInfoDouble(pSymbol,SYMBOL_ASK);
else if(pType == ORDER_TYPE_SELL) request.price = SymbolInfoDouble(pSymbol,SYMBOL_BID);
bool tic = OrderSend(request,result);
checkCode = CheckReturnCode(result.retcode);
if(checkCode == CHECK_RETCODE_OK) break;
else if(checkCode == CHECK_RETCODE_ERROR)
{
string errDesc = TradeServerReturnCodeDescription(result.retcode);
Alert("Open market order: Error ",result.retcode," - ",errDesc);
break;
}
else
{
Print("Server error detected, retrying...");
Sleep(RETRY_DELAY);
retryCount++;
}
}
{
if(pType == ORDER_TYPE_BUY) request.price = SymbolInfoDouble(pSymbol,SYMBOL_ASK);
else if(pType == ORDER_TYPE_SELL) request.price = SymbolInfoDouble(pSymbol,SYMBOL_BID);
bool tic = OrderSend(request,result);
checkCode = CheckReturnCode(result.retcode);
if(checkCode == CHECK_RETCODE_OK) break;
else if(checkCode == CHECK_RETCODE_ERROR)
{
string errDesc = TradeServerReturnCodeDescription(result.retcode);
Alert("Open market order: Error ",result.retcode," - ",errDesc);
break;
}
else
{
Print("Server error detected, retrying...");
Sleep(RETRY_DELAY);
retryCount++;
}
}
will this solve the warning properly?

Hello!
First, I'm new to MT5. I encountered OrderSelect and OrderSend on my sample code I try to study.
I have no idea how to fix it
it show "return value of 'OrderSend' should be checked"
"return value of 'OrderSelect' should be checked"
Thankyou
OrderSelect
OrderSelect(pTicket);
string errDesc = TradeServerReturnCodeDescription(result.retcode);
Print("Modify pending order #",pTicket,": ",result.retcode," - ",errDesc,", Price: ",OrderGetDouble(ORDER_PRICE_OPEN),", SL: ",request.sl,", TP: ",request.tp,", Expiration: ",request.expiration);
if(checkCode == CHECK_RETCODE_OK)
{
Comment("Pending order ",pTicket," modified,"," Price: ",OrderGetDouble(ORDER_PRICE_OPEN),", SL: ",request.sl,", TP: ",request.tp);
return(true);
}
else return(false);
}
OrderSend
else if(posType == POSITION_TYPE_SELL)
{
ask = SymbolInfoDouble(pSymbol,SYMBOL_ASK);
breakEvenStop = openPrice - (pLockProfit * SymbolInfoDouble(pSymbol,SYMBOL_POINT));
currentProfit = openPrice - ask;
if((currentSL > breakEvenStop || currentSL == 0) && currentProfit >= pBreakEven * SymbolInfoDouble(pSymbol,SYMBOL_POINT))
{
request.sl = breakEvenStop;
OrderSend(request,result);
}
else return(false);
}
do
