Hi to all, I wanted get data from MT4 via DDE server using Python.
For first test I've just tried:

Inserted Code
>>> import win32ui
>>> import dde
>>> server = dde.CreateServer()
>>> server.Create("MyMT4")
>>> conversation = dde.CreateConversation(server)
>>> conversation.ConnectTo("MT4","BID")
>>> conversation.Request("EURUSD.")
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
conversation.Request("EURUSD.")
dde.error: Request failed

the dot after EURUSD isnt misstake, thats my brokers name of the pair

this is my openoffice dde connection that works:
Inserted Code
=DDE("MT4";"BID";"EURUSD.")

Does anyone know why request doesnt working? thx for reply

it seems MT4 DDE server doesn't support DDE "REQUEST" method. you can use ADVISE loop

MT4 help:
Client Terminal / Tools / Export of Quotes
===============
Quotes are given through DDE only at incoming of new ticks (ADVISE mode), but not immediately on request (REQUEST mode) where the latest price is shown. N/A is shown on the first REQUEST, and after the new price has been income, quotes will appear
===============

thx for reply
it solved my problem.
if someone other is interested in:
module dde in pywin package doesn't support advise mode
I have found some ddeclients that worked (for example https://gist.github.com/noisywiz/2661065 ) in Python 2 not in Python 3

Hi Wenaaa,

Have you managed to run conversation.Advise("EURUSD") ?
I have the connexion established but I don't know how to import data.
