![]() Note here that only parameter “s” is mandatory. For example, parameter name “s” with value “GOOGL” gives parameter “s=GOOGL” that is then attached to the URL just after the question mark “?” as follow: Let’s take a closer look at the the URL parameters following the question mark. Parameter name and value must always be passed together and are separated by an equal sign “=“. These two parts are separated with a special character: the question mark. Now, if you look more closely at URL, we can see that it is composed of two main parts (one fixed and one variable): (1) the Web site and file name that is fixed, and (2) the parameters that can be modified in order to get historical data from other companies and/or for different periods of time. So, usually, we prefer to use the Adjusted Close Price instead of the Close Price. It may not necessary be equal to the price because of different business reasons. for a day, between market opening and closure). Finally, the stands for “Adjusted Close Price” and represents the final price at the end of the day after the market closed. day), is the lowest price for a specific time interval, and is the price after the market closed. represents the number of transactions executed during the given time interval (e.g. The first column contains the date for every measurement. Columns 3 to 5 contains stock prices, where represents the recorded price when the market (here NasdaqGS) opened, is the highest recorded price for a specific time interval (e.g. However, the number of columns (7) will always be the same for this API. The number of lines contained in the file depends on the given parameters (start data, end date and frequency). ,768.52002,769.200012,764.390015,765.840027,520600,765.840027Īs you can see, the returned CSV file always contains headers (column names) in the first line, columns are separated by comma, and each line contains measurements for a specific day. The table.csv file contains daily stock values of Google from the 24th to 30th December 2015.ĭate,Open,High,Low,Close,Volume,Adj Close Here is an example of data contained in this file. In our case, we are going to use the table.csv file. If you click on them, the first simply returns a Web page (as you would expect), while the second returns a CSV file called table.csv that can be saved on your computer. However, except the fact that there are tow distinct URLs, they are also quite different in the result they return. Note that these URLs both access stock data related to symbol GOOGL, i.e. And this is how the URL of Yahoo Finance API look like when accessing historical stock data:.This is how a URL look like when navigating on Yahoo Finance’s Web site:.We give here some two examples of Yahoo’s URLs. Now, the first step before writing any line of code is to understand how the Yahoo Finance API for Historical Stock Data is working, which implies to first learn how URL (Uniform Resource Locator) are built and used to access content on the Web. A URL is a Web address that your browser uses to access a specific Web page. For example, this is a link to access Apple’s historical data, where you can directly use the Web interface to display or hide stock prices and volumes. It is of course possible to access Yahoo Finance’s historical stock data using a Web browser. In this article, we use the API for Historical Quotes only. VBA can be used to import data automatically into Excel files using these APIs. Yahoo has several online APIs (Application Programming Interface) that provides financial data related to quoted companies: Quotes and Currency Rates, Historical Quotes, Sectors, Industries, and Companies. ![]() You can find the whole code source of this tutorial on GitHub, or you can download the following Excel file that contains the VBA code together with the Dashboard and a list of stock symbols: yahoo-hist-stock.xlsm. However, we hope to post other articles in a near future about more simple aspects of programming in VBA. In this article, we are going to show you how to download historical stock prices using the Yahoo Finance API called “table.csv” and discuss the following topics that will allow you successfully import data in Excel from Yahoo in a simple and automatic way:īefore we delve into the details of this subject, we assume that you know how to program in VBA or, at least, that you have already some notions of programming, as we are not going to introduce any basic programming concepts in this article.
