Financial Data Extraction from with Python

Project description

Financial Data Extraction from with Python

investpy is a Python package to retrieve data from, which provides data retrieval from up to: 39952 stocks, 82221 funds, 11403 etfs, 2029 currency crosses, 7797 indices, 688 bonds, 66 commodities, 250 certificates and 2812 cryptocurrencies.

investpy allows the user to download both recent and historical data from all the financial products indexed at It includes data from all over the world, from countries such as: United States, France, India, Spain, Russia or Germany, amongst many others.

investpy seeks to be one of the most complete Python packages when it comes to financial data extraction in order to stop relying on public/private APIs, since investpy is FREE and has NO LIMITATIONS. These are some of the features that currently lead investpy to be one of the most consistent packages when it comes to financial data retrieval.

In order to get this package working you will need to install it via pip (with a Python3.5 version or higher) on the terminal by typing:

$ pip install investpy

Additionally, if you want to use the latest investpy version instead of the stable one, you can just use the following command:

$ pip install git+

The developer branch ensures the user that the most updated version will always be working and fully operative so as not to wait until the stable release on the master branch comes out (which eventually may take some time depending on the amount of issues to solve).


You can find the complete investpy documentation at Documentation.

Notes: documentation is hosted on Read the Docs and generated using sphinx with the theme sphinx_rtd_theme which is the standard Read the Docs theme for sphinx.


Even though some investpy usage examples are presented on the docs, some basic functionality will be sorted out with sample Python code blocks. Additionally, more usage examples can be found under examples/ directory, which contains a collection of Jupyter Notebooks on how to use investpy and handle its data.

Recent/Historical Data Retrieval

investpy allows the user to download both recent and historical data from any financial product indexed (stocks, funds, etfs, currency crosses, certificates, bonds, commodities indices and cryptos). In the example presented below, the historical data from the past years of an stock is retrieved.

import investpy

df = investpy.get_stock_historical_data(stock='AAPL',
                                        country='United States',
             Open   High    Low  Close     Volume Currency
2010-01-04  30.49  30.64  30.34  30.57  123432176      USD
2010-01-05  30.66  30.80  30.46  30.63  150476160      USD
2010-01-06  30.63  30.75  30.11  30.14  138039728      USD
2010-01-07  30.25  30.29  29.86  30.08  119282440      USD
2010-01-08  30.04  30.29  29.87  30.28  111969192      USD

So as to get to know all the available recent and historical data extraction functions provided by investpy, and also, parameter tuning, please read the docs.

Search Data search engine is completely integrated with investpy, which means that any available financial product (quote) can be easily found. The search function allows the user tune the parameters in order to adjust the search results to their needs, where both product types and countries from where the products are, can be specified. All the search functionality can be easily used, for example, as presented in the following piece of code:

import investpy

search_results = investpy.search_quotes(text='apple',

Retrieved search results will be a list of investpy.utils.search_obj.SearchObj class instances. In order to get to know which are the available functions and attributes of the returned search results, please read the related documentation at Search Engine Documentation. So on, those search results let the user retrieve both recent and historical data from that concrete product, its information, etc., as presented in the piece of code below:

 for search_result in search_results[:1]:
   search_result.retrieve_historical_data(from_date='01/01/2019', to_date='01/01/2020')
{"id_": 6408, "name": "Apple Inc", "symbol": "AAPL", "country": "united states", "tag": "apple-computer-inc", "pair_type": "stocks", "exchange": "NASDAQ"}

Crypto Currencies Data Retrieval

Crypto currencies support has recently been included, so as to let the user retrieve data and information from any available crypto at Please note that some crypto currencies do not have available data indexed at so that it can not be retrieved using investpy neither, even though they are just a few, take it into consideration.

As already presented previously, historical data retrieval using investpy is really easy. The piece of code presented below shows how to retrieve the past years of historical data from Bitcoin (BTC).

import investpy

data = investpy.get_crypto_historical_data(crypto='bitcoin', from_date='01/01/2014', to_date='01/01/2019')

             Open    High    Low   Close  Volume Currency
2014-01-01  805.9   829.9  771.0   815.9   10757      USD

2014-01-05  924.7  1029.9  911.4  1014.7   21374      USD


Since investpy is intended to retrieve data from different financial products as indexed in, the development of some support modules which implement an additional functionallity based on investpy data, is presented. Note that anyone can contribute to this section by creating any package, module or utility which uses investpy. So on, the ones already created are going to be presented, since they are intended to be used combined with investpy:

  • pyrtfolio: is a Python package to generate stock portfolios.
  • trendet: is a Python package for trend detection on stock time series data.

If you developed an interesting/useful project based on investpy data, please open an issue in order to let me know so as to include it on this section.

Contribute - Open Source Helpers

As this is an open source project it is open to contributions, bug reports, bug fixes, documentation improvements, enhancements and ideas. There is an open tab of issues where anyone can open new issues if needed or navigate through them in order to solve them or contribute to its solving. Remember that issues are not threads to describe multiple problems, this does not mean that issues can't be discussed, but so to keep a structured project management, the same issue should not describe different problems, just the main one and some nested/related errors that may be found.

This Python package has been made for research purposes in order to fit the needs that does not cover, so this package works like an Application Programming Interface (API) of developed in an altruistic way.

Conclude that this package is not related in any way with or any dependant company, the only requirement specified by in order to develop this package was "mention the source where data is retrieved from".
