Using Screener Functionality with Finviz Elite Account

[NimaMPH]

Hi There,

How can I use screener with Finvize Elite account (similar to portfolio) to receive real-time data instead of delayed data?

Thanks,

Nima

I figured out how to obtain a cookie. But it does something weird to the scraper when you use it. My guess is because it's a different url. https://elite.finviz.com/screener.ashx rather than https://finviz.com/screener.ashx
Here's my quick code to get the cookie header. That's as far as I got for now, I may come back later and work on this more.

def get_auth_header():
    login_url = 'https://finviz.com/login_submit.ashx'
    data = {
        'email': os.environ['FINVIZ_USERNAME'],
        'password': os.environ['FINVIZ_PASSWORD']
    }
    response = requests.post(url=login_url, data=data)
    for history in response.history:
        if history.cookies:
            for c in history.cookies:
                if c.name == '.ASPXAUTH':
                    return {
                        'Cookie': f'{c.name}={c.value}'
                    }

example response:
print(get_auth_header())

{'Cookie': '.ASPXAUTH=1DC9E157078115DB9255E990EADE49A7C730035DEACF4F71559FF28438C6E10F92050B5AF0D3EA580F62565D75A8A9B788A099A3913C194C234710B1052C7DD74F942398AC78773BA8E82D1DC9E1570789031A9CC43D91A6C003C2A57C00D3DA7F40101EC2D1E9C56DDD8AB3F27E408A69BFA770789031A9025EDA596A4E38501A5CE079DA092104E392AF0D3EA580F62565D75A'}

Hi! Any luck with this? Were you able to get it working?

Hello, I managed to reuse @NathanHRich code in order to make it work on another finviz library called finvizfinance. It shouldn't be difficult porting the changes here. Is anyone still interested?
