tradingview-screener 3.1.0

Overview

pip install tradingview-screener

tradingview-screener is a Python package that allows you to create custom stock screeners using TradingView's official API. This package retrieves data directly from TradingView without the need for web scraping or HTML parsing.

Key Features

• Markets: Stocks, crypto, forex, CFDs, futures, bonds, and more.
• 3000+ Data Fields: OHLC data, technical indicators, fundamental metrics (e.g. P/E, EPS), and even internal TradingView-only fields.
• Timeframes: Use 1m, 5m, 15m, 30m, 1h, 2h, 4h, 1d, 1w, and 1mo — freely mix timeframes per field, no subscription required.
• Filtering: SQL-like syntax with full support for AND/OR logic.

Note that throughout the documentation, "field" and "column" are used interchangeably. Same with "Scanner" and "Screener".

Quickstart

Here’s a simple example to get you started:

from tradingview_screener import Query

x = (Query()
 .select('name', 'close', 'volume', 'market_cap_basic')
 .get_scanner_data())
print(x)

Output:

(17580,
          ticker  name   close     volume  market_cap_basic
 0   NASDAQ:NVDA  NVDA  127.25  298220762      3.130350e+12

 [50 rows x 5 columns])

By default, the result is limited to 50 rows. You can adjust this limit, but be mindful of server load and potential bans.

A more advanced query:

from tradingview_screener import Query, col

(Query()
 .select('name', 'close', 'close|1', 'close|5', 'volume', 'relative_volume_10d_calc')
 .where(
     col('market_cap_basic').between(1_000_000, 50_000_000),
     col('relative_volume_10d_calc') > 1.2,
     col('MACD.macd|1') >= col('MACD.signal|1')  # 1 minute MACD
 )
 .order_by('volume', ascending=False)
 .offset(5)
 .limit(25)
 .get_scanner_data())

Real-Time Data Access

To access real-time data, you need to pass your session cookies, as even free real-time data requires authentication.

Verify Update Mode

You can run this query to get an overview on the update_mode you get for each exchange:

from tradingview_screener import Query

_, df = Query().select('exchange', 'update_mode').limit(1_000_000).get_scanner_data()
df = df.groupby('exchange')['update_mode'].value_counts()
print(df)

exchange  update_mode          
AMEX      delayed_streaming_900    3255
NASDAQ    delayed_streaming_900    4294
NYSE      delayed_streaming_900    2863
OTC       delayed_streaming_900    7129

Using rookiepy

rookiepy is a library that loads the cookies from your local browser. So if you are logged in on Chrome (or whatever browser you use), it will use the same session.

1. Install rookiepy:

   pip install rookiepy
   

2. Load the cookies:

   import rookiepy
   cookies = rookiepy.to_cookiejar(rookiepy.chrome(['.tradingview.com']))  # replace chrome() with your browser
   

3. Pass the cookies when querying:

   Query().get_scanner_data(cookies=cookies)
   

Now, if you re-run the update mode check:

_, df = Query().select('exchange', 'update_mode').limit(1_000_000).get_scanner_data(cookies=cookies)
df = df.groupby('exchange')['update_mode'].value_counts()
print(df)

exchange  update_mode          
AMEX      streaming                3256
NASDAQ    streaming                4286
NYSE      streaming                2860
OTC       delayed_streaming_900    7175

We now get live-data for all exchanges except OTC (because my subscription dosent include live-data for OTC tickers).

Other Ways For Loading Cookies

from http.cookiejar import CookieJar

import requests
from tradingview_screener import Query


def authenticate(username: str, password: str) -> CookieJar:
    session = requests.Session()
    r = session.post(
       'https://www.tradingview.com/accounts/signin/', 
       headers={'User-Agent': 'Mozilla/5.0', 'Referer': 'https://www.tradingview.com'}, 
       data={'username': username, 'password': password, 'remember': 'on'}, 
       timeout=60,
    )
    r.raise_for_status()
    if r.json().get('error'):
        raise Exception(f'Failed to authenticate: \n{r.json()}')
    return session.cookies


cookies = authenticate('<your-username-or-email>', '<your-password>')
Query().get_scanner_data(cookies=cookies)

Comparison to Similar Packages

Unlike other Python libraries that have specific features like extracting the sentiment, or what not. This package is but a (low-level) wrapper around TradingView's /screener API endpoint.

It merely documents the endpoint, by listing all the functions and operations available, the different fields you can use, the markets, instruments (even some that you wont find on TradingView's website), and so on.

This library is also a wrapper that makes it easier to generate those verbose JSON payloads.

Robustness & Longevity

This package is designed to be future-proof. There are no hard-coded values in the package, all fields/columns and markets are documented on the website, which is updated daily via a GitHub Actions script.

How It Works

When using methods like select() or where(), the Query object constructs a dictionary representing the API request. Here’s an example of the dictionary generated:

{
    'markets': ['america'],
    'symbols': {'query': {'types': []}, 'tickers': []},
    'options': {'lang': 'en'},
    'columns': ['name', 'close', 'volume', 'relative_volume_10d_calc'],
    'sort': {'sortBy': 'volume', 'sortOrder': 'desc'},
    'range': [5, 25],
    'filter': [
        {'left': 'market_cap_basic', 'operation': 'in_range', 'right': [1000000, 50000000]},
        {'left': 'relative_volume_10d_calc', 'operation': 'greater', 'right': 1.2},
        {'left': 'MACD.macd', 'operation': 'egreater', 'right': 'MACD.signal'},
    ],
}

The get_scanner_data() method sends this dictionary as a JSON payload to the TradingView API, allowing you to query data using SQL-like syntax without knowing the specifics of the API.
