Jaanga geeDoc: S&P 500 Motion Chart


At last, every symbol of the Standard & Poor 500 index displayed in a single motion chart - Jaanga geeDoc SP500.

You can view the instant instant replay of the last 15 to 20 minutes of trading simply by dragging the slider bar at the bottom of the screen.

The S&P 500 is the reference standard of market indices, so it feels appropriate to use this index as the reference standard for Jaanga development. The standard that needs to be achieved is to display as many of the activities as possible of 500 different organizations in as close to real-time as possible while still open to as much technical augmentation and human interaction as possible.

Putting it another way, you must forget how you do it on paper. The current way of proceeding is to look at an entire market (or whatever data set) but only to be able to see one symbol at a time. It's like having some weird camera pointed towards many people walking up and down a sidewalk that can only show you one person at a time.

The Jaanga camera wants to show you everybody - all the stocks - so you can see just how everybody moves together. Everybody avoids that hole in the pavement. They all stop when the light turns red. Real-time data behaves the same way. The era of looking at one item at a time must come to an end. We must begin to see markets and other data as moving swarms. This is the only way to readily identify outliers or black swan events.

About Jaanga: John Tukey + Exploratory Data Analysis = Awesomeness

John Tukey - courtesy Wikipedia

John Wilder Tukey (June 16, 1915 – July 26, 2000) was an American statistician.

I am not a statistician and, as yet, have only the vaguest notion of the history and development of statistics and the visualization of data. Therefore there may well be even more wonderful figures in the world of statistics to honor. But for the moment John Tukey provides me with more than enough delight and inspiration.

Why is Tukey so cool?

Tukey invents the computer terms: "bits" and "software". Actually there's a byte more than that.

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 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?
