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?

If you have finviz elite account, you don't need to "hack" the auth request with username/password. Finviz elite now has a dedicated api for exporting screener data.
