My name is Mark Ursell, and I am an individual trader and investor. I am continually working on developing new trading strategies and improving my existing strategies. I have developed a series of Excel backtest models, and you can learn more about them on this site.
Thank you Prateek, that is a good question. Yahoo Finance only offers daily, weekly and monthly historical data. If you have an online source of intraday data you can use the Excel data import function to get it directly into your spreadsheet. One suggestion is to try MT4, lots of brokers offer it, and you can download historical data directly from the platform.
As you might expect, Excel can do more than recording simple actions. In fact, Excel can also record more complex action such as importing external data. Now you know where we am going! The idea is to first start recording a macro and then import external data as shown in the previous chapter. Hence, if you import the CSV file called table. As you can see, both macro are using an essential object to import external data, namely the QueryTable object. You can think of this object as containing a Query that produces a Table once executed.
Depending on the method chosen to import data, that connection string can be quite different. In our case, we have the following connections. The rest of the Macro is actually composed of parameters that configures the QueryTable object to obtain the appropriate behavior.
There are two groups of parameters: general parameters shared by both Macros and specific parameters that are related to the data source i. Web vs. We are not going to explain every parameters here you can read the official documentation to this purpose , but only the most important ones. RefreshStyle property tells how the data should be written into the given Excel sheet.
Should the new table override exiting data or should it be inserted? Instead, you should use xlOverwriteCells in order to override cells containing data. Refresh is not a property but a method: it execute the query and start importing the data in your Excel sheet. If you omit this line, nothing will happen. Additionally, this method can take an optional parameter called BackgroundQuery. This tells Excel if the query should execute synchronously or asynchronously.
TextFileParseType indicates whether the fields in your text files are delimited by specific characters such as commas or tabs xlDelimited , or if columns are delimited by specific width xlFixedWidth. In our case, the CSV file is delimited by characters. TextFileTextQualifier designates the type of text qualifier, i.
In our case, we let the default value xlTextQualifierDoubleQuote , i. These parameters are not important for the remaining of our task. However, the WebTables property is an essential parameter to import data from Web pages, as it indicates which tables that appear on the Web page should be imported.
In this case, table number 15 is imported, but it is possible to import more than one table at once. The key idea is then to set up a QueryTable objet for a text file as this corresponds to the returned data , while uing the address of the Yahoo Finance API in the connection string. The resulting connection string is therefore as follow:. And these are parameters with their values that should be used to configure and correctly import the data from the received CSV file:.
Now, using the above connection string and parameters, we can build a macro that is able to automatically download historical data from Yahoo Finance:. Not only is this solution elegant, it is also very efficient! In fact, we do not need to parse or format the using a slow loop, as this is directly done by the QueryTable object. Now, the last step is to provide a dashboard in Excel so that users can directly interact with Yahoo Finance, without having to work with VBA.
In the following formula, I am taking the result from Yahoo! If you want to use the same formula for a bunch of different ticker symbols, you can link your formula using a cell reference. Here is the same formula from Example 1, however it is now point to a ticker symbol in cell A2. Here is a list of the variables and what they pull in:. As you might imagine, if you are pulling realtime data from Yahoo!
Therefore, you will need to manually recalculate your sheet keyboard shortcut F9 in order to refresh your formulas. As of May , it has been reported that Yahoo! I found this response from a Yahoo employed moderator in their forums:. I'm not sure what the end goal is for this move, maybe they will begin offerring a paid service in the future.
Due to this recent event, the below VBA code to pull historical data from Yahoo! Finance has a ton of historical data for stocks and harnessing VBA's automating power to pull this data in seconds can allow you to perform some unbelievable tailor-made analysis. Also, the Excel Table is named "StockTable". See if you can follow along with the VBA as it pulls data directly from Yahoo! Finance and places it into Excel. There is a little extra clean up you need to do since the query is pulled into excel as a CSV comma separated values data set.
You can just leave this extra column blank if you do not need to perform any extra calculations.
