Financial Data 101
Financial data comes in many forms. The canonical format is tabular data (think spreadsheets) which can be formatted as rows and columns. This type of data is available from many sources such as finance.yahoo.com, Quandl, Alpha Vantage, and many brokerages.
Pandas
Pandas is a powerful data science library that stores tabular data into memory in a very efficient manner. It makes the opening, processing, and subsequent saving of data fast and effective. It comes with a range of helper methods, data classes, and in the case of financial data—web APIs!
Required Libraries
Now that we know what to expect from our data, let’s consider how to get some financial data using Python! Before we get started, make sure the following packages are installed as they will be relevant for each data source. We’ll cover specific packages as we move along.
Using the Data
Getting historical stock prices in Python is all well and good but what is one to do with such data? There are tones of approaches for analyzing OHLC data—allowing one to distill many numbers of useful insights based on expected outcomes and use-case. Below are some projects that can get you started:
Review
We’ve seen here that getting financial data in Python can be approached in many ways. Whether via official APIs, well-supported third-party libraries, or even hacked-together approaches there seems no shortage of OHLC data to be had.
Method 1: Using Yahoo Finance
We can get stock using the yfinance.download () function provided in the yfinance module which is a module for Yahoo’s Finance API. We can download the module using the following command.
Method 2: Using Pandas DataReader
Another way of getting the historical stock data is to use the pandas_datareader library. It also uses Yahoo’s Finance API to load in the data. We can download the module using the following command.
Method 3: Using Quandl
Quandl has hundreds of free and paid data sources, across equities, fixed incomes, commodities, exchange rates, etc. In order to get the access, we need to create an account on Quandl and get an API Key to access the data for free. After that, we need to download the API support quandl library of python using the following command.
