4. Install Requests sudo pip install requests
5. Install Requests-HTML sudo pip install requests_html (this one is requires Python 3.6 and is used with trading-view data provider)

Please, do the following:

1. You need to obtain a valid API key for SMS.RU service
2. You need to create a file key.txt, and insert the API key into the file
3. You need to create a file config.txt, and insert your phone number into the file (please look into example config-example.txt)
4. You need to create a task with autostarting stock-watcher.py. You can do it via crontab or via systemd
5. You need to create a task with server rebooting (because this allows you to flush sent SMS counter)
6. You need to make stock-watcher.py executable (chmod +x)

this allows reboot server every day at 04:05 am (at server local time)
