Every day all around the globe money is changing hands in the hope of turning it into more and more money. The most popular vehicle? Stock markets. Stock markets used to be localized to countries or cities. Today, they are global intertwining networks of activity. Your father might tell you that these shares trade between brokers and wealthy clients, but Wall Street has changed over the past decade. Today, more shares are traded through automated algorithms than by anything else.
Yet despite what many have called the over-complication of the stock market, trading has become more democratized. More people than ever have the ability to take part in the greatest wealth creation machine of a capitalist economy.
This applies to the rise in algorithmic trading as well. Even the average retail investor now has the power to get in on the trading action from their laptops through various platforms and APIs. There are many free and reputable API services out there to give historical information for your algorithms and trading decisions. As a day trader dealing in U. One of the most popular and free API providers out there has been a company by the name of Alpha Vantage. Alpha Vantage is a community of researches and engineers who provide an API for real-time and historical time-series data.
The data accessed can be from stocks, forexand even cryptocurrencies. What I found from using their API for stock research was that it was super easy to set up and use even without world-class programming skills.
As you can see, anyone can get started with using python for the stock market. But python code for stock market prediction? For meaningful data that will influence trading decisions, technical indicators can be helpful. Connect to the Alpha Vantage API In Alpha Vantage, many of the top technical indicators used by professional traders can be accessed with a basic structure.
Now you see what can be done with this API. Other technical indicators supported include exponential moving averages EMAweighted moving averages WMAvolume-weighted moving averages, moving average convergence divergence MACDand more! Data is great, but raw data in an HTML file with no ease of manipulation is not going to yield much profit.
After installing the Excel add-on, each excel workbook will have the Alpha Vantage tab at the top of the page.First published on The Data Wrangler. As a stock trader I need a ready of supply stock market data for analysis and visualisation. That data is needed for decision making and I often render it to a chart to better understand it.
The free Yahoo financial API was the place to go for stock market data. It's also free and very easy to use. Alpha Vantage offer both daily and intraday data and I have created an open-source command line app for downloading it. This posts introduces alpha-vantage-cli. I'll show you how to use this tool to download stock market data. I'll give examples of use both from the command line and also using it as an API from your Node.
Alpha Vantage is free, but to use it you must sign up for an API key. Please follow this link to sign up:. The examples that follow use the 'demo' API key, please be aware that this has very limited usage. You can use alpha-vantage-cli as a command line application to download stock market data to a CSV file. First you need to have Node.

Don't forget to replace the API key with your own! The example code above gets daily data. Getting intraday data is almost the same, just use the getIntradayData function instead. Would you like help getting started with alpha-vantage-cli? Would you prefer to use a desktop app instead of a command line tool? Please become a patron of The Data Wrangler and I will be happy to help you. It's fairly easy to download data manually.
You can try out yourself by opening the following link in your browser:.
That link downloads the recent price history for Microsoft as a CSV file. To use it for any other company you'll need to sign up for your own API key.You can access the data directly in Python or any other programming language of your choosing. From there, you can manipulate the data or store it for later use. Alpha Vantage proudly offers its service for free. They provide a generous rate limit of 5 requests per minute and requests per day.
Several premium plans are available if you require a higher rate limit. Alpha Vantage offers historical and realtime data for stocks, forex, and cryptocurrencies. Several time frames are available ranging from 1-minute bars up to monthly.
In addition to price data, there are more than 50 technical indicators available as well as performance data for 10 US equity sectors. The biggest advantage is that its free. Further, the data is extensive. We found price data dating back 20 years for stocks and forex. Cryptocurrency data for assets like Bitcoin went back as far as in terms of daily price data.
You may not want to use the Alpha Vantage API if you already have access to price data through your broker. Data can differ from one provider to another and its best to use broker data if you plan to execute trades. Along the same lines, some automated systems are very sensitive to small differences in data between different providers. Paid data providers often boast that they have the most accurate data available.
Unfortunately, they no longer offer an official API. Their offering is a bit more extensive compared to Alpha Vantage. However, their rate limits can be a little tricky as each endpoint carries a different weight in terms of how many requests you can make. Another alternative is worldtradingdata. The process is quick and easy and a key is necessary for all the requests. You can see what kind of data is being offered, but more importantly, this is where you can figure out which parameters are required for each API request.
You will likely be referring to it a lot. This is certainly a case where you can get away without using the library, although it does make things a bit easier. After installing the Alpha Vantage library, it is a good idea to store your API key as an environment variable. This is an extra security precaution so that your key is not visible in plain text within your code. There have been instances where individuals have pushed code to their public GitHub page only to have someone exploit their key, so this step is highly recommended.
Windows — Click Start and type in environment variables. You should see an option to Edit environment variables for your account. Make sure to use your actual API key for the value. You can confirm that the environment variable is saved by typing in the following which should display your API key:. If the environment variable comes up blank in Python you made need to restart your code editor for the changes to take effect.
The library is set up in such a way that each of the 5 sections within the Alpha Vantage API documentation has been coded in a separate file within the library. You will have to import the appropriate part of the library and instantiate the class within it. Here is an example. In the above code, we import the TimeSeries class from timeseries. We then instantiate the TimeSeries class to inherit all of its functions. Otherwise, the library will automatically grab the API key from the environment variable for you.
Our next step is to grab some data. There are several options available under the Stock Time Series section of the Alpha Vantage documentation.Learn the data science skills to accelerate your career in 6-months or less.

The API wrapper can be used to retrieve historical prices such as intraday or daily prices for global equities and ETFs. The package is currently in alpha status.
It has not been used extensively yet and therefore mainly of the potential quirks of Alpha Vantage's actual API may not be accounted for. We plan on using this wrapper for price history charting in our company lookup and ratings tool. This library is intended to provide a simple wrapper with minimal dependencies, and does not intend to introduce pydata stack dependencies numpy, pandas, etc.
Contributions are welcome. Someone can immediately contribute by building out wrappers for the rest of the API such as FX rates or crypto prices.
Navigation Project description Release history Download files. Project links Homepage. Maintainers pmart Status The API aims to support equity time-series data as a first step. Design Consideration This library is intended to provide a simple wrapper with minimal dependencies, and does not intend to introduce pydata stack dependencies numpy, pandas, etc.
Differences with existing wrappers for the Alpha Vantage API include: Library Differences No Pandas dependencies or optional dependency Focuses on simplifying data for ingesting Avoids logical branching making the code simpler only two if statements at moment Provides symbology mapping references The library carries out some conveniences versus using the API without a wrapper. Conveniences Converts timestamps to UTC time when applicable.
Simplifies record field names i. Appends the timestamp field to record vs. Uses time ascending list versus a dictionary for price record data structure. Returns multiple tickers over a given parameter set using threads. Maps ticker symbology from other vendors.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The data frame structure is given by the call on alpha vantage rest API. The column names of the data frames are the ones given by their data structure. For example, the following call:. Would result on:. The headers from the data are specified from Alpha Vantage in previous versions, the numbers in the headers were removed, but long term is better to have the data exactly as Alpha Vantage produces it.
Giving us as output:. The foreign exchange is just metadata, thus only available as json format using the 'csv' or 'pandas' format will raise an Error.
