I've got an error on backtesting on MT4:

Installed MtApi to MT4's "MQL4\experts" folder, and MTConnector.dll to "MQL4\Libraries" folder, and added that to user's environment PATH.
When dropping MtApi on a chart getting this:
2016.09.30 00:29:12.208 Expert MtApi NZDCAD,H1: removed
2016.09.30 00:29:12.207 MtApi NZDCAD,H1: uninit reason 8

2016.09.30 00:29:12.169 MtApi NZDCAD,H1 inputs: Port=8222;
Any help on how to troubleshoot it? Does it fail to find the MTConnector.dll? If so, what should be its location?
Functions GetOrder (and GetOrders) returns object order with empty symbol.
This problem has been occurred in version 1.0.27 after refactoring mql part.
Hi,
It is a way to use indicators in Backtesting mode, i have always a exception if i try to use it.
I have also a problem with OrderSend in Backtesting mode, i get always a exception with a concurency mode error.
Thanks in advance

Hello,
Thanks for your api everything is working. But I have a problem;
If I download MtApi_Setup.exe and install it, MTConnector.dll size 494 KB ( Working )
If I built MTConnector project, MTConnector.dll size 485 KB and notworking (MetaTerminal MtApi.ex4 not load file there is no smiling face in the upper right corner)
Thanks.
Memory usage of MetaTrader 4 grows rapidly when using MtApi.
To reproduce start a backtest in MT4 with the strategy tester (one day is enough), run app below (which does nothing but connect), watch the memory usage of the MetaTrader process in the task manager quickly grow to several GB's.
using MtApi;
using System;
namespace MT4ClientConsole
{
class Program
{
static void Main(string[] args)
{
MtApiClient client = new MtApiClient();
client.BeginConnect("127.0.0.1", 8222);
Console.ReadKey();
}
}
}
Hi!
The type of volume (lot size) in MtApi.mq4 (line: 3537) could be double:
double volume = jo.getDouble("Volume");
for more accurate position sizes.
Hello, I'm getting error in reading the IsConnected () method. However the quotes data is being received. I'm using a thread to execute a particular method and I noticed that before the call is made in this method the _apiCliente.IsConnected () statement is set to true. But when I enter the private method it is false. :(
Visual Studio error:
Exception thrown: 'MtApi.MtConnectionException' in MtApi.dll
Additional information: Client is not connected.
Could not load file or assembly 'Newtonsoft.Json, Version=8.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.
Стабильно появляется такая ошибка.
Воспроизводится это как API перестаёт работать - выдаёт результат OK, но нулевые данные (что само по себе плохо, тут не видно что API поломался).
Далее, при закрытии MT5, появляется окошко MtApi с сообщением из сабжа.
После перезапуска MT, API начинает работать некоторое время и далее по кругу.
From Amir Aghashahi:
iCustom function not working .. before and after change(because Backstep cannot be greater or equal to Depth) param value in your example for Zigzag .. I use it in other code with RSI .. iCustom donot reply value .. only reply Zero in all time in all my test
I could not find support for SymbolInfoDouble. Are there plans to develop? Can I develop and make pull request?
MtApi5 не работает (не переходит вMt5ConnectionState.Connected после BeginConnect) если объект откуда я вызываю Connect и задаю ConnectionStateChanged унаследован от ReactiveObject (фреймворк reactiveui).

An exception is thrown when trying to call an apiclient function from the QuoteUpdated event when backtesting in MT4:
An exception of type 'MtApi.MtConnectionException' occurred in MtApi.dll but was not handled in user code
Additional information: Service connection failed! This operation would deadlock because the reply cannot be received until the current Message completes processing. If you want to allow out-of-order message processing, specify ConcurrencyMode of Reentrant or Multiple on CallbackBehaviorAttribute.
The code below for a test console app fails on call to iBars
for instance:
using MtApi;
using System;

{
MtApiClient client = new MtApiClient();
client.QuoteUpdated += Client_QuoteUpdated;
client.BeginConnect("127.0.0.1", 8222);
Console.ReadKey();
}

{
var bars = ((MtApiClient)sender).iBars(symbol, ChartPeriod.PERIOD_M5);
Console.WriteLine("Bars: " + bars);
}
}
}
Is it possible to send message to the Experts tab of Tools window of MT?
Hello
Is there any sample code for MetaTrader API in asp.net/MVC, I would appreciate if some one can send me any code, I am new to both MetaTrader API and asp.net/mvc.
Thanks in anticipation
Планируется ли поддержка индикаторов?
Hi,
the WIX installator is missing MTConnector.dll, so whole release is broken. Version before has same fault.
MQL uses different color representation than C# System.Drawing.Color.
MQL4 color ( https://docs.mql4.com/basis/types/integer/color ):
0x00BBGGRR
00: ignored values
BB: Blue component
GG: Green component
RR: Red component
System.Drawing.Color ( https://msdn.microsoft.com/en-us/library/system.drawing.color%28v=vs.110%29.aspx ):
0xAARRGGBB
AA: Alpha component
BB: Blue component
GG: Green component
RR: Red component
A possible fix in MtApiColorConverter.cs
:
using System.Drawing;
namespace MtApi
{
class MtApiColorConverter
{
public static Color ConvertFromMtColor(int mqlColor)
{
return Color.FromArgb((byte)(mqlColor), (byte)(mqlColor >> 8), (byte)(mqlColor >> 16));
}
public static int ConvertToMtColor(Color color)
{
return color == Color.Empty ? 0xffffff : (Color.FromArgb(color.B, color.G, color.R).ToArgb() & 0xffffff);
}
}
}
Is it possible to add sync bool Connect function to MtApi5?
Priority is Lowest as soon we always can use AsyncConnect, but sync may be useful sometimes.
The behavior may be following: waiting 5 s, if no connection, then return false.
As advanced feature here may be if no connection, additional checking that MT5 is running, if no, start it in minimized mode and retry connection.
В MQL есть методы SymbolsTotal(), SymbolName() и SymbolSelect(). Было бы здорово получить доступ к ним через MtApi4.
In 1.0.33 version MT5Connector.cpp needs MtServerInstance replacing with MtAdapter
My Metatrader 5 Build 1545 on Windows 10 crashed on call bool initExpert(int expertHandle, int port, string symbol, double bid, double ask, string& err); in MTApi EA.

Is this a bug? Or I have created the mt5connector.dll incorrectly. I am using VS15
At least in MtApi5 it is bad defined.
Puropose: for deserialization.
I can prepare pull request if needed.
Hi,
after compilation in VS2015, EA load in MT4 and after that crash on error.

Hello,
The OrderStopLoss() and OrderTakeProfit() methods are deprecated, but there are no StopLoss and TakeProfit properties in MtOrder.
hi guys.
i cant draw any object on charts with Api.
Arrows, Lines, Fibos, HorizantalLines, Trends, VerticalLines, Image, ....
is there any method to do that ?
thanks.
When I started my application I got
log4net:ERROR RollingFileAppender: INTERNAL ERROR. Append is False but OutputFile [C:\Users\Alexey\AppData\Local\Temp\MtApi5Client\Logs\2016-04-11--23-46-42.txt] already exists.
I am not sure what is reason, but looks like there is a initialization of logging from MtApi5.dll itself. I think it is not good way to initialize logging from library and it should be initialized from client application (for instance add appropriate API call) and library itself should only add messages logging calls (they will find log instance correctly).
I am using such configuration in my client (looks like same logging framework is used):
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.WriteTo.Trace()
.CreateLogger();
Hello,
Can you provide a readme file for your code? I am not be able to build it with VS2013. Maybe, you can list some dependencies. Thanks in advance.
Version 1.0.25 has bug in function GetOrders. It returns orders only from trading pool.
Expected behavior: GetOrders returns orders from trading pool and history pool by input parameter.
(Thanks John Fitton to find this issue).
It is uint instead of ulong
Hi. This is not really a bug, but more of a feature request.
I came over a little quirk when it comes to debugging the EA in Visual Studio. I found that the timeout between MT4 server and .NET client is the .NET default (60 seconds).
Is it possible to make the timeout configurable for debugging purposes?
Is it possible to have MtApi
work with multiple symbols without having to drop the EA on each individual chart?
