How to enable data I/O with _DWX_MTX_SEND_MARKETDATA_REQUEST_ ?

[Jim2002]

Hi there, first of all, thanks for the great project, secondly I'm not sure if I am the only one having this issue or not but when I called _zmq._DWX_MTX_SEND_MARKETDATA_REQUEST_() , noting is return to the ipython console, but for some reason I cannot request the market data. . In mt4 however this is printed in the Experts tab 2019.09.23 22:54:53.640 DWX_ZeroMQ_Server_v2.0.1_RC8 EURUSD,M1: DATA;EURUSD;1;2019.01.04 17:00:00;2019.09.23 22:52:00 . I can open orders, close orders......etc . Subscribing only works if I change Publish_MarketData in the EA from false to true
Please help. Cheers

Python version: 3.7.2
zmq version: 18.1.0
dwx-zeromq-connector version: 2.0.1

Hi @Jim2002 ,

Thank you for your kind feedback, glad to hear you're finding the project useful!

Yes, that's correct - the Server EA needs to be publishing market data before a client application can request it.

Data will not be returned if the EA input parameter Publish_MarketData == False.

To enable market data publication, this needs to be set to True in order for your application to subscribe to the data.

For further details and troubleshooting assistance, please watch the following video where we've outlined this and a few other common questions to help your user experience:

Publish_MarketData has been set to True however _zmq._DWX_MTX_SEND_MARKETDATA_REQUEST_() still didn't return anything.

Hi @Jim2002 ,

Could you please provide some sample function calls here to show how you're using the method?

Also, could you confirm that you can see MetaTrader publishing the data in your Experts tab in MetaTrader?

p.s. Please do make sure to watch this video as it may well have the solution to any debugging you're currently conducting:

Thanks for the reply, I have already watched the video.

I'm trying to request bar data using Python from mt4, I noticed the _DWX_MTX_SEND_MARKETDATA_REQUEST_() method where I can request Close price from one time to another so I decided to try the method but it turns out it doesn't return anything. I haven't write any function calls using this method yet, just want to make sure this method works.

The Experts tab is publishing 2019.09.23 23:42:18.876 DWX_ZeroMQ_Server_v2.0.1_RC8 EURUSD,M1: Sending EURUSD 1.098420;1.098460 to PUB Socket

I found out when I start from more recent timestamp, the method works. eg: _zmq._DWX_MTX_SEND_MARKETDATA_REQUEST_(_start='2019.09.23 12:00:00',_timeframe=1) , this will return data length of 108 values, if I change the start time from 2019.09.23 12:00:00 to 2019.09.23 11:00:00 , the method no longer works.

Don't know if it'll help to other fellows, but in my case worked subsequent command:
_zmq.DWX_MTX_SEND_MARKETDATA_REQUEST(_sybmol='EURUSD', _timeframe=30, _start="2020.2.26", _end="2020.2.29 10:00:00")

So, in my case, problem was with date entering. When I used '2020.2.29', or "D'2020.2.29'" format, it didn't work properly. Think, that it will work properly now.

Thanks again to Darwinex Team!
