Here is the complete code where i am trying to use ForexConnect().get_history(.... instead of fx.get_history( and i do not want this line of code "with ForexConnect() as fx:" how to achieve this ,the last section of code given produces excpetion issues .

Why i do not want to use "with ForexConnect() as fx:" The reason is once the session "with ForexConnect() as fx:" the function is logged out .My idea is to be in the session after once logged in .So i do not want to try this with "with ForexConnect() as fx:"

import argparse



import pandas as pd

from forexconnect import ForexConnect, fxcorepy

parser = False

    parser = argparse.ArgumentParser(description='Process command parameters.')

    common_samples.add_main_arguments(parser)

    common_samples.add_date_arguments(parser)

    common_samples.add_max_bars_arguments(parser)

    args = parser.parse_args()

    return args

Here i want to login once and be in the logged in session forever.
With the below function this is working fine .But here the problem is once the With section is over the session is disconnected.

with ForexConnect() as fx:

    try:

        fx.login(str_user_id, str_password, str_url,

                 str_connection, str_session_id, str_pin,

                 common_samples.session_status_changed)

        history = fx.get_history(str_instrument, str_timeframe, date_from, date_to, quotes_count)

            current_unit, _ = ForexConnect.parse_timeframe(str_timeframe)

To stay in the session tried the below code without using the "With" and as :

Here the login is successful but could not get the data in history = ForexConnect().get_history

Error Code :

                ForexConnect().login(str_user_id, str_password, str_url,

                    str_connection, str_session_id, str_pin,

                    common_samples.session_status_changed)

               **history = ForexConnect().get_history(str_instrument, str_timeframe, date_from, date_to, quotes_count)**

How to make it the ** ** code work without any exception error without using With --- as : keyworkds.
what is the alternative for this with and as : why when i try to access as history = ForexConnect().get_history ( ... it is giving error how to overcome this issue.
