Getting Cookies

TradingView may present captcha challenges when scraping ideas or requiring authentication for WebSocket-based indicators in the Streamer class. To continue scraping without interruptions and access protected indicators, you need to obtain and use a valid session cookie.

Captcha Frequency

TradingView typically requires captcha verification every 24 hours. When you encounter a captcha error, you'll need to repeat this process to get a fresh cookie.

Follow these steps to get a valid TradingView session cookie after solving the captcha:

  1. Open the Ideas Page: Navigate to https://www.tradingview.com/symbols/BTCUSD/ideas/ in your web browser.

  2. Open Developer Tools: Press F12 to open the browser's developer tools and switch to the Network tab.

  3. Solve the Captcha: If a captcha challenge appears, complete it manually.

  4. Refresh the Page: After solving the captcha, refresh the page to ensure a clean request.

  5. Capture the Request: In the Network tab, look for the GET request to https://www.tradingview.com/symbols/BTCUSD/ideas/ (usually at the top of the list).

  6. Extract the Cookie:

    • Select the request
    • Go to the Headers section
    • Find the Cookie header in the request headers
    • Copy the entire cookie value

With Ideas Scraper

from tv_scraper import Ideas

# Your copied cookie string
TRADINGVIEW_COOKIE = r"paste_your_cookie_string_here"

# Initialize scraper with cookie
ideas_scraper = Ideas(cookie=TRADINGVIEW_COOKIE)

# Scrape ideas
ideas = ideas_scraper.get_ideas(symbol="BTCUSD", exchange="CRYPTO", start_page=1, end_page=5)

With Streamer (for Indicators)

from tv_scraper import Streamer

# Initialize streamer with cookie
s = Streamer(cookie=TRADINGVIEW_COOKIE)

# Get candles with indicators (requires auth)
result = s.get_candles(
    exchange="BINANCE",
    symbol="BTCUSDT",
    indicators=[("STD;RSI", "37.0")]
)

Cookie Expiration

The cookie remains valid for approximately 24 hours. After that, you'll need to repeat the process to get a new cookie when scraping encounters captcha challenges or indicator authentication fails.
