Do you want to build your own indicators or your own strategies in stock market for buying or selling a stock based on historical data? Or you simply want to see what was the price of a particular stock 2 months back and 3 months back? Finding historical data for a particular stock is not very easy unless you have some paid software or you have a broker account which shows chart on screen. But there is a better way to achieve this, answer is Google finance.
Google Finance along with Google Spreadsheet can solve your problem of fetching historical data for any stock, and doing your own calculation or research based on the historical data. Best part of this setup is you don’t need to manually update data every day, it updates by itself giving you fresh data every time you open your spreadsheet and that too without any overhead on your computer or without delays.
I will here explain you how to fetch historical data for any stock listed on National stock exchange India, but you can do it for any exchange supported by Google Finance. All you need is Google Account, access to Google drive and some basic knowledge of excel or Google Spreadsheet. Let’s say we want to Fetch 20 days historical data of Infosys limited which is listed on NSE, which includes Open, High, Low, Close and volume of the day, the method described here is perfect for you.
The above screenshot is taken from the spreadsheet I created to pull historical data from Google finance sheet, in this you have to provide Stock Code, Exchange code and frequency of data you want to pull (daily or weekly), rest everything is taken care by Google by simply passing these values to GOOGLEFINANCE Function in build in Google Spreadsheet.
Formula used here which is written in cell A5 is =GOOGLEFINANCE(D2,”all”,WORKDAY.INTL(today(),-50),today(),C2). There is another formula used in spreadsheet to construct the Google finance code (cell D2) from given input which is =CONCAT(B2,”:”,B1) which gives value in D2 = “NSE:INFY”, which is google finance code for Infosys ltd listed at National Stock Exchange.
First Argument to function GOOGLEFINANCE() is Google finance code of Stock required which is referred from Cell D2.
Second argument here is “All”, this returns all price values along with volume for the day, which includes Open Price, High Price, Low Price and Close price. In case you don’t need all of these you can change this argument to get desired values.
The third and fourth argument are from date and to date, you can pass date dynamically like we did here to get auto updating data or you can mention specific dates in case you need data for those dates only.
Here also please note that end date or to date is optional but if you don’t specify the function will return only 1 day data for specified date.
Last argument used is for period of data fetched, it can be either weekly or Daily data.
Now as you have data fetched, you can do whatever calculation you want on these data, but wait before we end this tutorial have you noticed Google Finance is giving data in reverse order that is latest data in last?
Well this can be solved by simply putting Sort on top of Google finance query, see the above screenshot, we used following formula instead of originally mentioned above to achieve this =Sort(GOOGLEFINANCE(D2,”all”,WORKDAY.INTL(today(),-50),today(),C2),1,0), as shown in above screenshot.
