Problem with logging in on website - python w/ requests

[snippsat]

Selenium is too slow for me. That's why I try to write this with requests

Can run Selenium in headless(not loading browser) then is faster.
When logged in can send source browser.page_source to BS for parse with lxml.
This is way easier the trying to do this with Requests/BS on a JavaScript heavy site.
Also when have .page_source can do serval operation at same speed.
Example setup bid_size and price_sales or more will have good same speed after the setup and catch of .page_source is done.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
import time, sys

#--| Setup
options = Options()
options.add_argument("--headless")
options.add_argument('--disable-gpu')
#options.add_argument('--log-level=3')
browser = webdriver.Chrome(executable_path=r'C:\cmder\bin\chromedriver.exe', options=options)
#--| Parse or automation
browser.get('https://www.morningstar.com/stocks/XOSL/XXL/quote.html')
#time.sleep(1)
soup = BeautifulSoup(browser.page_source, 'lxml')
bid_size = soup.select('div.dp-value.price-down.ng-binding.ng-scope')
price_sales = soup.select('li:nth-child(9) > div > div.dp-value.ng-binding')
print(price_sales[0].text.strip())
print(bid_size[0].text.strip())

Output:
