investpy is a Python package to retrieve real-time historical data from Investing. It provides historical data retrieval from up to 29.628 stocks, 81.024 funds, 11.366 etfs, 1.889 currency crosses, 7.797 indices and 721 bonds. Basically, investpy allows you to download historical data from almost all the financial products indexed in Investing.com. All the data that can be retrieved includes data from all over the world, from countries such as: United States, France, India, Spain, Russia or Germany, amongst many others. Therefore, investpy is intended to wrap up all the available data from Investing.com, so that it can be retrieved via Python for its further usage and/or analysis.
investpy seeks to be one of the most complete Python packages when it comes to historical data extraction of financial products in order to stop relying on public/private APIs, as 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 of financial data retrieval.
In order to get this package working you will need to install investpy using pip on the terminal by typing:
$ pip install investpy==0.9.7
Every package used is listed in requirements.txt file, which can also be installed via pip:
$ pip install -r requirements.txt
Even though some investpy usage examples are shown on the docs, some basic functionality will be sorted out with sample Python code blocks.
As the main functionality is based on historical data retrieval, the usage of stock data retrieval functions will be explained so to ease the use of investpy, which is mainly intended for historical data extraction, which means that every other function is additional.

As financial data is really complex and sometimes both the product name/symbol and the country are unknown for the user, in terms of what does investpy expect, every financial product listed in investpy (which currently includes stocks, funds, etfs, indices and currency crosses) has its own search function. Search functions allow the user to search among all the available stocks for example, whenever just one field is known (even though it is not the exact match). So on, a basic example on stock search by the ISIN code is presented below:
import investpy
search_results = investpy.search_stocks(by='isin', value='ES0113211835')
print(search_results.head()) country name full_name isin currency symbol
0 mexico BBVA Banco Bilbao Vizcaya Argentaria SA ES0113211835 MXN BBVA
1 mexico BBVA Banco Bilbao Vizcaya Argentaria S.A. ES0113211835 MXN BBVA
2 belgium BBVA Banco Bilbao Vizcaya Argentaria SA ES0113211835 EUR BBVA
3 spain BBVA Banco Bilbao Vizcaya Argentaria S.A. ES0113211835 EUR BBVA
4 united kingdom BBVA Banco Bilbao Vizcaya Argentaria Sa ES0113211835 EUR BVAB
As Investing.com provides more data besides the historical one, some of that additional data can be fetched via investpy. Currently, as the package is under-development, some additional functions have been created in order to retrieve more data as indexed in Investing.com.
All the functions definitions and usage can be found in the Documentation!
Since investpy is just intended to retrieva data from different financial products as indexed in Investing.com, the development of support modules is presented, which implement an additional functionallity based on investpy data. Note that anyone can contribute to this section by creating any package, module or utility which uses this package. So on, the ones already created are going to be presented, since they are intended to be used combined with investpy:
- investpy_portfolio: is a Python package to generate stock portfolios.
- trendet: is a Python package for trend detection on stock time series data.
As this is an open source project it is open to contributions, bug reports, bug fixes, documentation improvements, enhancements and ideas.
Also there is an open tab of issues where anyone can contribute opening 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 issues, this does not mean that issues can't be discussed, but if new issues are reported, a new issue should be open so to keep a structured project management.
Additionally, you can triage issues on investpy CodeTriage so you can provide issues so the package can grow and improve as the issues solves bugs, problems or needs, and maybe provide new ideas to improve package functionality and efficiency.
This Python package has been made for research purposes in order to fit the needs that Investing.com does not cover, so this package works like an Application Programming Interface (API) of Investing.com developed in an altruistic way. Conclude that this package is not related in any way with Investing.com or any dependant company, the only requirement specified by Investing in order to develop this package was "mention the source where data is retrieved from".
