What is Finviz?

FinViz aims to make market information accessible and provides a lot of data in visual snapshots, allowing traders and investors to quickly find the stock, future or forex pair they are looking for. The site provides advanced screeners, market maps, analysis, comparative tools, and charts.

Important Information

Any quotes data displayed on finviz.com is delayed by 15 minutes for NASDAQ, and 20 minutes for NYSE and AMEX. This API should NOT be used for live trading, it’s main purpose is financial analysis, research, and data scraping.

Quick Start

import finviz

# Get stock data
stock = finviz.get_stock('AAPL')
print(stock['Price'], stock['P/E'], stock['Market Cap'])

# Get news
news = finviz.get_news('AAPL')
for timestamp, headline, url, source in news[:5]:
    print(f"{timestamp} - {headline} ({source})")

# Get insider transactions
insiders = finviz.get_insider('AAPL')
for trade in insiders[:3]:
    print(trade['Insider Trading'], trade['Transaction'], trade['Value ($)'])

# Get analyst price targets
targets = finviz.get_analyst_price_targets('AAPL')
for target in targets:
    print(target['analyst'], target['rating'], target.get('target_to'))

Using Screener

The Screener allows you to filter stocks based on various criteria. You can either build filters programmatically or copy them from the FinViz website URL.

from finviz.screener import Screener

# Screen for large-cap NASDAQ stocks in the S&P 500
filters = ['exch_nasd', 'idx_sp500', 'cap_largeover']
stock_list = Screener(filters=filters, table='Overview', order='price')

print(f"Found {len(stock_list)} stocks")

for stock in stock_list[:10]:
    print(stock['Ticker'], stock['Company'], stock['Market Cap'])

# Export to CSV
stock_list.to_csv("stocks.csv")

# Export to SQLite
stock_list.to_sqlite("stocks.sqlite3")

Available Tables:

• Overview - Basic company info, market cap, price

• Valuation - P/E, P/S, P/B, PEG ratios

• Financial - ROA, ROE, ROI, margins

• Ownership - Insider/institutional ownership, short interest

• Performance - Price performance across timeframes

• Technical - RSI, SMA, volatility, beta

Initialize from URL:

# Copy filters directly from FinViz website URL
url = "https://finviz.com/screener.ashx?v=111&f=cap_largeover,exch_nasd&o=-marketcap"
stock_list = Screener.init_from_url(url)

Get Available Filters:

# Get all available filter options
filters = Screener.load_filter_dict()
print(filters.keys())  # ['Exchange', 'Index', 'Sector', 'Industry', ...]

Individual Stock Functions

#           'P/E': '34.26', 'Market Cap': '3755.76B', 'Price': '255.53', ...}

# Recent news with timestamps

# Returns: [{'Insider Trading': 'COOK TIMOTHY D', 'Relationship': 'CEO',
#            'Transaction': 'Sale', 'Value ($)': '41,530,891', ...}, ...]

# Analyst ratings and price targets
targets = finviz.get_analyst_price_targets('AAPL', last_ratings=10)

#            'rating': 'Overweight', 'target_from': 200, 'target_to': 220}, ...]

# All market news (not ticker-specific)
all_news = finviz.get_all_news()

Using Portfolio

from finviz.portfolio import Portfolio

portfolio = Portfolio('<email>', '<password>', '<portfolio-name>')
print(portfolio)

# Create portfolio from CSV
portfolio.create_portfolio('My Portfolio', 'positions.csv')

CSV format for portfolio import:

Transaction: 1 = Buy, 2 = Sell. Empty optional fields use today’s data.

Downloading Charts

stock_list.get_charts(period='d', chart_type='c', size='l', ta='1')

# period: 'd' (daily), 'w' (weekly), 'm' (monthly)
# chart_type: 'c' (candle), 'l' (line)
# size: 's' (small), 'l' (large)
# ta: '1' (show technical analysis), '0' (hide)

Configuration

• DISABLE_TQDM=1 - Disable progress bars

Async Support:

The Screener supports async requests for faster data fetching:

stock_list = Screener(filters=filters, request_method="async")
