otmql4zmq's Issues

mql4zmq.dll/uZmqReceive Access Violation

Not quite sure why it works or what i exactly did but increasing the iRequestPtr size from 1 to 32 (line 80 ZmqSendReceive.mq4) seems to fix the access violation and therefore to enable receiving messages via zmq_recv.

If anybody knows why this is working or has an explaination for me i'd love to know what i'm doing here, hehe.

I've built the mql4zmq.dll against together with the latest version of zmq+libsodium with the trivial changes needed to make it run with zmq>2.

cheers

OTZmqCmdEA.mq4 requires mql4zmq.mqh but it only resides in legacy directory

see:

https://github.com/OpenTrading/OTMql4Zmq/blob/master/MQL4/Experts/OTMql4/OTZmqCmdEA.mq4#L20

https://github.com/OpenTrading/OTMql4Zmq/blob/master/net/Git/github.com/AustenConrad/mql4zmq/mql4zmq.mqh

This file should have a non-legacy counterpart in ./MQL4/include/OTMql4 directory

OTZmqCmdEA.mq4 does not compile

It requires a bunch of unavailable .mqh files. Is this expected?

zmq_send() & zmq_recv() - "Bad address" error and MetaTrader crash

Hi!
I created a simple client in mql4 to communicate with my java program on port 5555.
0MQ_client.txt
Unfortunately zmq_send() & zmq_recv() return "-1" and zmq_errno() for both of them returns 14, which corresponds to "Bad address" error message.
Could you tell me what might be the problem?

Essential informations:

• Windows 10 64 bit
• MetaTrader version 4.00 build 1065 installed from FOREX.com
• OTMql4Zmq from git

Thank you in advance!

Will this work with Metatrader 5?

Sorry for putting this question here: Didn't find any other place to contact the developers.

I would like to know if this will work with Metatrader 5. And if not, is there any plans to port it to Metatrader 5.

'uAnsi2Unicode' - function not defined OTMql4Zmq.mqh 134 16

Where can I get this function?

creole markup rendering on github is broken, leaving 404 urls

Some links like the one in Readme.creole:

Metatrader using OTMql4Py (https://github.com/OpenTrading/OTMql4Py). 

Leave the closing ) as part of the url. Then the url

https://github.com/OpenTrading/OTMql4Py)

Is 404,

Could we switch to an alternate creole url syntax or leave a space after url end to mitigate the broken url issue?

OTZmqCmdEA EURUSD,H4: s_recv: Warning! Message has zero length.

When I attach OTZmqCmdEA to a chart.

I get lots of these messages, about 10 per second:

2015.08.18 18:26:24.621 OTZmqCmdEA EURUSD,H4: s_recv: Warning! Message has zero length.

I wonder if it could be related to: #1

Garbled Message published from OTMql4Zmg

The first 16 bytes of a message published from OTMql4Zmg are sometimes (not always)
garbled, including nulls. The rest of the message is fine. The workaround it to pad the
message with 16 bytes.

I checked with wireshark and it is garbled in the transmission.

I checked in Mt4 and it is going to the dll OK - StringToCharArray is not the culprit.

Pity I can't run metatrader under a debugger...

it many files. Please Check

uAnsi2Unicode - function not defined on OTMql4Zmq.mqh

Metatrader says it cannot open mql4Zmq.ex4 file. First I fixed the import on the OTMql4Zmq.mq4 expert advisor so it includes OTMql4Zmq.mqh. But then when I compile both .mqh and .mp4 I get errors. "uAnsi2Unicode - function not defined on OTMql4Zmq.mqh"
I used dependency walker to check the mql4zmq.dll and it says: "Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module."
I tried everything from putting all the required .dll's in the same folder or different versions and nothing works
I am working on Linux, running Metatrader 64 bit, build 1010 with wine. I am using the pre-compiled libs from git.

OTMql4Zmq over PyZmq failure at import zmq

Hi,

i'm pretty new to python so i'm not sure if i'm doing anything wrong but running OTPyTestZmqEA.ex4 fails with the following message:
2015.11.26 10:28:21.576 2015.06.01 00:00 OTPyTestZmqEA EURUSD,M1: PANIC: PANIC: import zmq failed:<type 'exceptions.WindowsError'> : [Error 126] Das angegebene Modul wurde nicht gefunden which basically means the module wasn't found in english.

reading the logfile it seems that there is a problem when including the file libsodium.pyd:

vPyInit - Thread Dummy-3 number 13360
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Python27\lib\site-packages\zmq\__init__.py", line 45, in <module>
    _libsodium = ctypes.cdll.LoadLibrary(bundled_sodium[0])
  File "C:\Python27\lib\ctypes\__init__.py", line 431, in LoadLibrary
    return self._dlltype(name)
  File "C:\Python27\lib\ctypes\__init__.py", line 353, in __init__
    self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] Das angegebene Modul wurde nicht gefunden
INFO : vPyDeInit Closing outfile

i did some digging but can't come up with the reason why it can't find the module as it is where bundled_sodium[0] is pointing. Furthermore importing zmq via import zmq in the python cli does work without any problems, which makes me wonder if there is some kind of difference in how the python process is handled when created by OTMql4Py.

I'd appreciate some help.
Thanks

Strings Leaked

Essential information for reporting Issues:

• What version of Windows and 32/64 bit: Wine on Ubuntu 17
• What Build number of Metatrader: 1090
• Where was the Metatrader installed from: FXCM
• OTMql4Zmq from git, or what version of the OTMql4Zmq installer: Pre-compiled DLLs ZMQ2.0.10

Works fine sending etc. but whenever my program exits I am always getting a lot of strings leaked. Literally just using the example EA to send mkt data updates on each new tick. Any insight would be great.

Cannot compile EA: "#import was not closed"

I installed from source (latest version). After copying all the files I saw that the libraries mq4 are compiled to ex4 successfully. However, when I try to compile the EA, I'll got these errors:

'OTMql4/OTLibLog.ex4' - #import was not closed OTLibLog.mqh 9 9
'OTMql4/OTLibStrings.ex4' - #import was not closed OTLibStrings.mqh 13 9
'OTMql4/OTLibSimpleFormatCmd.ex4' - #import was not closed OTLibSimpleFormatCmd.mqh 9 9
'OTMql4/OTLibJsonFormat.ex4' - #import was not closed OTLibJsonFormat.mqh 6 9

'OTMql4/ZmqSendReceive.ex4' - #import was not closed ZmqSendReceive.mqh 12 9

Anyone has the same issue like me?

now that Issue #1 is closed should this comment be removed?:

I think their is a left over comment:

Windows 10: OTMql4ZmqTest 8 tests failed

Hi there,
I'm facing a issue with OTMql4Zmq and I'm not sure if that's because of Win10 or the problem is between the screen and the back of a chair.

I copied all files (+OTMql4Lib) and I can load the OTMql4ZmqTest script.
Result:

2016.05.12 14:39:51.158 OTMql4ZmqTest USDCHF,H1: WARN: TestErrorMessages 8 failed

2016.05.12 14:39:51.158 OTMql4ZmqTest USDCHF,H1: WARN: 115 'Unknown error' != 'Unknown error'

2016.05.12 14:39:51.156 OTMql4ZmqTest USDCHF,H1: initialized

So basically every test fails and I have no idea why.
My idea is to connect MT4 to a java server (this works already) and listen to it.

Essential information for reporting Issues:

• What version of Windows and 32/64 bit:
  Windows 10 x64
• What Build number of Metatrader:
  950
• Where was the Metatrader installed from:
  metaquotes
• OTMql4Zmq from git, or what version of the OTMql4Zmq installer:
  git

Thank you in advance,

EDIT: just found out, that the CmdEA is working...

Cannot call 'OTMql4/mql4zmq.dll::mql4zmq_strerror', 'OTMql4/mql4zmq.dll' is not loaded

I installed everything including OTMql4Zmq, OTMql4Py and OTMql4Lib. There are some #import keywords missing for some header files in OTMql4 so that the compilation in MT4 failed. I fixed that locally. I suggest you to update and change them. Another problem I encountered is

Cannot call 'OTMql4/mql4zmq.dll::mql4zmq_strerror', 'OTMql4/mql4zmq.dll' is not loaded

When I am trying to drag script OTMql4ZmpTest to one graph.

Cannot call 'OTMql4/mql4zmq.dll::mql4zmq_init', 'OTMql4/mql4zmq.dll' is not loaded

When I am trying to use EA called OTZmqCmdEA. Do you know why this happened? I tried to find some hints from wikis of your git repo but cannot. Please help me!

My windows is 64 bit windows 8. Metatrader 4.
