Donald Bradley's Siderograph is a planetary index developed
in 1948 that works very well to forecast daily and weekly charts. Unfortunately
the Bradley Siderograph does not work with the short term time frames on
intraday charts. In order to use the Siderograph on intraday chart Mr. Mikula
developed a compression function that would adjust the Siderograph so it worked
on intraday charts. This new indicator is name the "Fractal Siderograph"
because the compression function used is based on Chaos math fractal
compression routines. This indicator is intended to be a planetary index that
will work on 15 minute, 30 minute and 60 minute charts. The index is not
effective for time frames shorter than 15 minutes and larger than 60 minutes.
The MarketWarrior Fractal Siderograph indicator makes it very easy to create
your own custom intraday planetary index. The chart below shows the Fractal
Siderograph on a 15 minute chart for the stock GE.

The next chart below shows the Fractal Siderograph pivot forecast four days in to the future.
