Features

• 📊 yfinance-style API - Familiar interface for stock/fund data

Installation

pip install python-avanza

Quick Start

import avanza

# Get stock data
stock = avanza.Stock("5361")  # Avanza Bank Holding
stock.info['name']
stock.price

# Get historical data
history = stock.history("one_month")

# Get dividends
dividends = stock.dividend

Finding orderbook_id:

• Search: avanza.search("company name")
• Avanza URL: https://www.avanza.se/aktier/om-aktien.html/5361/... → ID is 5361

Search for Instruments

# Search for stocks
results = avanza.search("volvo", instrument_type="stock", limit=5)
for hit in results['hits']:
    hit['instrument']['name'], hit['instrument']['id']

# Search for ETFs
results = avanza.search("ishares", instrument_type="etf")

# Search for funds
results = avanza.search("avanza", instrument_type="fund")

Fund Data

# Create a fund ticker
fund = avanza.Fund("41567")

# Get fund info
fund.info['name']
fund.price['nav']

# Historical data
history = fund.history("one_year")

Cache Management

# Default: 60 second cache
stock = avanza.Stock("5361")

# No caching (always fresh)
stock = avanza.Stock("5361", cache_ttl=0)

# Custom cache duration (5 minutes)
stock = avanza.Stock("5361", cache_ttl=300)

# Manual refresh
stock.refresh()  # Clear cached data

Time Periods

# Use strings
stock.history("one_week")
stock.history("one_month")
stock.history("one_year")

# Or use enum
stock.history(avanza.TimePeriod.ONE_WEEK)

Available periods: today, one_week, one_month, three_months, this_year, one_year, three_years, five_years, infinity
