unable to receive data//DWX_ZeroMQ_Connector_v2_0_1_RC8//_DWX_MTX_SUBSCRIBE_MARKETDATA_ #102

Hello guys, Thank you very much for maintaining this project. I'm facing a problem at early stage. bug1 bug2 It's okay to send orders into MT4. MT4 Server is able to send out data. I'm not able to receive data locally via Python.

Could you help me to figure out the problem? thanks.

Hi, did you run the track prices function?

_zmq._DWX_MTX_SEND_TRACKPRICES_REQUEST_(['EURUSD'])

You probably did because else I think MT4 would not send prices. I just ran subscribe+trackprices and it works, so I can't reproduce the error.

Hi, elvinex, Thank you for your reply. May I know if you are using version 2.0.2 or 2.0.1? because there's no function called _DWX_MTX_SEND_TRACKPRICESREQUEST() in DWX_ZeroMQ_Connector_v2_0_1_RC8.py

thanks.

bug3 when I print self._Market_Data_DB, it returns empty. no idea how I can make it work..

Hi, The function name has an underscore at the end like this _DWX_MTX_SEND_TRACKPRICES_REQUEST_().

https://github.com/darwinex/dwx-zeromq-connector/blob/master/v2.0.1/python/api/DWX_ZeroMQ_Connector_v2_0_1_RC8.py

Btw. we removed version 2.0.2 (or rather included the changes into 2.0.1), so there is only one version now.

Did you delete and replace all old files? Source code and libraries?

I'm trying so. actually I didn't know there was an update because it's still 2.0.1.

I will update after I refresh everything.

thanks.

Running this in ipython console worked for me:

from DWX_ZeroMQ_Connector_v2_0_1_RC8 import DWX_ZeroMQ_Connector
dwx = DWX_ZeroMQ_Connector()
dwx._DWX_MTX_SEND_TRACKPRICES_REQUEST_(['EURUSD'])
dwx._DWX_MTX_SUBSCRIBE_MARKETDATA_('EURUSD')

dwx._DWX_MTX_SUBSCRIBE_MARKETDATA_('EURUSD')

Yes. _DWX_MTX_SEND_TRACKPRICESREQUEST([]) is a new function in new file. And I udpated new DWX_ZeroMQ_Server_v2.0.1_RC8.mq4 as well. And now it works~~~ Thank you very much elvinex~~~
