Google Finance: your personal financial assistant
Google Finance is a financial service, providing comprehensive information about corporations, listed on North American exchanges, about the quotes of their shares. Unlike many Google services, this one is not localized yet. So Russian users will have to deal with the English-language interface..
To use the service, you must have a Google Account. After that, the first time you log into Google Finance, you will find a lot of business information - business news, reports from stock exchanges, data about, which sectors of the economy (healthcare, energetics, transport, technology, etc.) rose, video plots, etc..
Once you add company stocks to your virtual portfolio, which you plan to follow, the picture will change significantly - with each subsequent visit to Google Finance, you will also see news on these companies of interest.
In general, Google Finance is ideal for two tasks - finding information about companies, whose shares are listed on the stock markets, and tracking changes in the value of shares of corporations, in which you invested your funds.
When you type in the search bar, for example, Avtovaz, Google Finance will offer several options during typing., trying “predict”, what exactly are you interested in. Let it be “Volzhsky automobile plant”, therefore, we will choose from the proposed options AVTOVAZ OAO (AVAZ). Google Finance will inform you almost immediately, what does the company do (for example, “AvtoVAZ” according to Google, in addition to car production, it is active in sectors such as insurance, banks, finance), where it exports its products, how many employees, what is the legal address and telephone number. Furthermore, you will even get information about the management of the company - who and what position, what is their age. The only thing, what, in my opinion, is missing - these are links opposite the names for searching on the Internet (to find out, for example, former place of work).
When, if you are interested in a western company, the amount of information will be even more. You will not just be informed, who runs the company, but they will also give links to the biographies of managers, will show their photos. If the company has a corporate blog, you will be given his address.
When you study information about a certain company, pay attention to the Related Companies section, in which similar companies are represented. Although this list is not compiled by hand, he's pretty accurate. For “Lukoil” Only Russian companies are listed as Related Companies.
The statistics of the company's performance is quite detailed and has about 20 positions (the figure fluctuates depending on the amount of data provided).
Any information can be useful when deciding whether to buy or sell shares.. Google Finance displays more than news headlines, but also excerpts from blog posts. So for the sake of completeness, you can familiarize yourself with them.. If you subscribe to the RSS news feed of the corporation of interest, you will read it in your favorite RSS reader. In Google Finance, you can create discussion groups for each company to discuss news and events.
A distinctive feature of Google Finance is integration with other services of the search giant. If a listed company provides data on the schedule and plans for holding meetings, advice, conferences, etc., they can be imported to Google Calendar. And then you won't miss,for example, Lukoil Earnings Conference Call.
Google Finance also has tools for visual presentation of information.. In particular, the service displays convenient charts changes in stock prices. You can define time intervals for viewing, and also make comparisons with shares of other companies. Let's say, you are a Google and Yahoo shareholder! Interesting to know, which corporation turned out to be more profitable for you? It's easy with Google Finance.
Conveniently organized management of stock portfolios. Firstly, you can create as many portfolios, how much will it take (say, one with shares of energy companies, the other is technological, third - pharmaceutical, etc.). Secondly, within the portfolio, you can specify transactions (purchase-sale, Commission, explanatory note). Thirdly, all data can be saved in a CSV file for further work in a financial program or a familiar spreadsheet processor.
Interesting, that Google Finance did not follow the Web20 fashion and did not develop collaboration tools - only those who know your username and password to Google Account can view and edit stock portfolios.
The disadvantages of Google Finance include the lack of notifications by e-mail or SMS about changes in the value of shares.. As a result, you will not recognize, when the stock price of the company you are interested in dropped to the required level or, on the contrary, did not rise to the expected value.
Summarizing, I will note, that my impressions of using Google Finance are extremely positive. It is a powerful and user-friendly service., focused not on professional brokers (it probably won't suit them), but for ordinary users, private investors, of people, who want to keep their savings.
Regarding the usefulness of Google Finance for Russians, then this question is difficult. We are not used to keeping money in stocks yet, besides, GF only tracks those companies, what are represented in the North American markets. But, On the other hand, more and more domestic corporations are placing shares on foreign exchanges. Besides, Google Finance is also a great guide to companies, so it's never too late to follow in Ingebor Motz's footsteps..

Getting real-time data from Google Finance
There is a class of algorithms, based on the correlation of asset prices in different markets. For that, to investigate such correlations, for example, between the American and Russian markets, it is necessary to have access to real-time data from Western exchanges, the supply of which is offered by special providers for a fairly substantial fee., it is possible to use parsing of real-time data from the Google Finance website instead of a paid data feed. On such data, a high-frequency strategy, certainly, don't build, but for slower strategies, this method is fine.. However, at high frequencies there is no strong correlation with the Americans for a long time, and HFT algorithms do not work with this idea, but for long periods of time there is a very wide field for research. How to get data from Google Finance discussed in the blog Pawel Lachowicz, the translation of which is presented below.
In this post we will cover, how to get real time data, broadcast on the Google Finance website, to use them as initial backtest data or in a real trading application. This data can be used for intraday trading systems.. The title of the post shows an example of displaying Apple quotes on Google Finance.
The core of our code, written in Python, is a small function, for a specific company ticker on a Google site, it parses data directly from the site, getting the last current price of the asset:
For the program to work correctly, you need to make sure, that the ticker is written correctly (as below). Further, display the local current time on the screen and then replace it with New York (exchange) time. We doing this, since we will get stock prices, traded on NYSE или NASDAQ. If you want to get the values of the English index FTSE100, then you need to change the time to universal (London):
By doing this, apply a third party function combine to put all read data into a Python list variable:
At the entrance, we submit the ticker of the company of interest to us from the Google website:
for which we open a new text file, where we will save all requests in real time:
Next, we create the final cycle for the entire trading day.. In our example, we get the latest data in 16:00:59 New York time. Key parameter of the program – variable freq, where we set the frequency of intraday data slicing (in seconds). The author has identified, that the optimal value would be 600 sec (10 min), since with more frequent requests, Google Finance can record high activity from your IP and consider it a flood. However, you can find the smallest value for your IP.
To check, how the program works in practice, the author launched it 9 January 2014 years New York time 03:31:19. The received data was written to a file in the following form:
It is important to note, what time, which we write down and try to associate with the time of the received quote, is the local computer time, so don't expect equal time spacing between values and great commit precision. However, in our case, when we want to assess correlation over fairly long periods, the accuracy of timing is not so important, as is the case with high frequency strategies. Let's pay attention , what if the internet connection is unstable, gaps in the data may appear, as seen in the above example.
The presented code can be easily modified., if you want to receive data on several assets at once. Just replace some of the code of the above program, starting with the definition of the ticker variable, with the following code:
Recording quotes in real time turned out like this:
where we can see the values of the current prices for 6 shares and one exchange-traded fund ETF every 10 minutes.
In custody, add on my own, that it would be interesting to investigate the correlation between American and Russian commodity companies, there may be a good temporary gap.
