Jaanga gDocs: Easy Start to Viewing 50 Stocks at Once

A major objective of the Jaanga web site is to provide you with easy-to-use tools for viewing large quantities of numbers. Certainly some of the techniques presented here may be complex or time-consuming, but there should always also be some quite accessible methods.As they say:

Space travel won't take off until everyone does rocket science in backyards.

The accompanying chart can be use to monitor up to fifty stock symbols and indices. The sample file displays all thirty stocks in the Dow Jones Industrial Average - all editable, zoomable and clickable. There may be some rocket science here, but it's just serving to make the technology more accessible.

About Jaanga: Tufte is so Old School, Tufte is so New Cool

We can say that Edward Tufte is the world's chief curator on the visual display of quantitative information. As c2.com says. Tufte wants you to "show people as much data as possible with as little ornamentation as possible". Tufte has been doing this sunce 1975 and there's probably no one better at doing this than Tufte.

But what is the "this" that Tufte does?

Jaanga gDocs: Entire US Stock Market in Single Chart

6,670 Symbols - Every US stock in one chart - Image captured 01-27-2011

Admittedly this chart has too many data points too close together to be of much analytical use, nevertheless this image is remarkable for two reasons.

1. The first element is that any time you load the underlying Google Docs spreadsheet, Google Docs automatically retrieves and updates the data from Nasdaq. Nasdaq publishes data for every stock listed on the NYSE, AMEX and Nasdaq itself. As of today's writing that is 6,670 symbols. The data includes symbol, price, market capitalization, full company name, industry & sector, year of IPO, latest price as well as a link to the Nasdaq web page with latest data. That's over 53,000 fresh data-points that arrive at your desktop within seconds of your asking. And it works every time.

About Jaanga: The Deluge of Data

Image from the Economist's Special Report on managing information

If you look at the About Jaanga page it says. "The thesis of this web site is that if the world is to prevail over the deluge of data then entirely new methods of displaying that data must be established."

So what is this "Deluge of Data"?

It's been around for some time. The Boston Globe says five centuries: Information overload, the early years.

Processing the Deluge of Data Using Google Docs

The thesis of this web site is that if the world is to prevail over the deluge of data then entirely new methods of displaying that data must be established.

Some of these methods may require huge data centers and exotic transmission methods. If, however, such methods are to be widely implemented and provide insight to large numbers of people, then at least at some level, the methods must be made accessible and understandable using readily available and inexpensive tools.

I am extremely happy to report that you can create highly insightful charts using Google Docs Spreadsheets that process many thousands of data points in near real-time.

Just as exciting is that the spreadsheets are not demos but display actual usable data. The data is is not delayed, the data arrives in a matter of seconds or so after the actual transaction.

The link below allows you to access three spreadsheets that in total provide you with the current movements of the 6,600+ stock on the three major US exchanges. You can just view a chart but you are really encouraged open up the spreadsheets and use these to create your own charts.

Why Do You Want Photorealistic Charts?

From: Creating 3D Chart  in Papervision 3D

A thesis of this site is that those six Bloomberg screens that the aging hedge fund dude stares at will soon become a scenario of a sunset industry.

The Wii/Kinect generation will perform very similar functions but the kids will interact with the numbers in the mileau of an evolved First Person Shooter (FPS).

Instead of numbers flashing there will be flows and patterns and particle physics and more.

So, of course, there will be anti-aliaising, smooth shading and high frame rates per second.

But do you really need shadows, day light and photo realism when you are doing mere data analysis?

Jaanga enables you to monitor and compare large numbers of stock symbols in near real time for free. At any given moment it's really easy to spot the outliers .

The desired goal: It just works.

Jaanga is an ongoing project. In the next few weeks and months here are some of the features and benefits you might start seeing:
