"to pocket" feature does not work for me so I am having the difficulties to copy post (copy with translation with the link to the original post)
from here to the Russian forum -

You can try to post on Russian Python thread here https://www.mql5.com/ru/forum/306688/page72

If not so let me know, and I will post on that thread using html feature (but it will take some time):

You can't do much because the terminal blocks when it's downloading rate data from the trade server. Even if you use async, threading, multiprocessing, you still run into the issue of a blocked terminal on subsequent calls. You could spawn multiple processes connected to multiple terminals and use one worker to handle priority fast tasks and another to handle a queue of long running blocking requests. 

Hi, 

Could you  please elaborator on how to do this "spawn multiple processes" ? I've been trying to achieve this by using multiprocessing and timeout in process.join(timeout=10), but that doesn't seem to work, the terminal gets stuck on updating a ticker and dosen't move on to the next. my code locks something like this:

def rates(ticker):
    utc_to = dt.datetime(year=2020, month=7, day=30)
    utc_from = utc_to - dt.timedelta(days=30)
    with mt5.connected():
        rates = mt5.copy_rates_range(ticker, mt5.TIMEFRAME_D1, utc_from, utc_to)
        print(pd.DataFrame(rates))

def main():
    tickers = ['tick1', 'tick2', 'ticker3', 'ticker4', ...]
    for ticker in tickers:
        p2 = Process(target=rates, args=(ticker,))
        p2.start()
        p2.join(timeout=10)
        p2.terminate()


if __name__ == "__main__":
    main()

Hi, Can anyone advise how to add account info after the datetime expiry in mql4 file

Good day Coders

Please assist, I am having challenge when downloading TIMEFRAME_M1 in python. I can only download prices for TIMEFRAME_M5 going upwards.This started when I recently updated MT5. Please have a look at my code below.

import numpy as np
import pandas as pd

from datetime import datetime
import MetaTrader5 as mt5
import pytz
# display data on the MetaTrader 5 package
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)

# establish connection to MetaTrader 5 terminal
if not mt5.initialize():
    print("initialize() failed, error code =",mt5.last_error())
    
# set time zone to UTC
timezone = pytz.timezone("Etc/UTC")

#create 'datetime' objects in UTC time zone to avoid the implementation of a local time zone offset
utc_from = datetime(2020, 1, 1, tzinfo=timezone)
utc_to = datetime(2020, 1, 11, hour = 13, tzinfo=timezone)

ratesUJ = mt5.copy_rates_range("USDJPY",  mt5.TIMEFRAME_M1, utc_from, utc_to)
#ratesUJ = mt5.copy_rates_range("USDJPY",  mt5.TIMEFRAME_M5, utc_from, utc_to)
# shut down connection to the MetaTrader 5 terminal
mt5.shutdown()

# create DataFrame out of the obtained data
ratesUJ =  pd.DataFrame(ratesUJ)
print(ratesUJ.head())

I am an experienced database developer but a Python rookie.
System W10 on 64 bit.

I get some errors with the installation of the MT5 package, depite that I think I have done everything properly:

* downloaded Python 3.9
* checked the PATH option

* checked that PIP is up to date > "requirements up to date"
* upgraded SETUP and WHEELS
* added ...\Python39\scripts to PATH
* downloaded MetaTrader5-5.0.33-cp39-cp39-win_amd64.whl (122.0 kB)
*  pip install MetaTrader5

Anyone? Your help is greatly appreciated!
