Market Analyst Software has put together several of my technical tools as described in my books and course and made them "plug in" modules for their trading software. Their Gann Analyst program is state of the art (Market Analyst Website) and I would certainly recommend it to you if you need a good software program to trade with and make a study of the markets. On this site I will try and explain my tools included in this software package, their origin and how to use them to make serious money.
The "Jenkins Box" was introduced in the advanced section of my course and because of the incredible popularity of this method by traders around the world who made a lot of money with it, the Market Analyst people wanted to program it into their program. It starts from a low usually, and from the first impulse high a series of angles are drawn to create geometric boxes that grow in size but are related to the initial impulse seed of the chart pattern. These boxes expand by a basic factor implicit in the Gann Square of Nine and is also one of the root factors of the Great Pyramid. The actual specifics of the growth spiral is to be found in my course but if you use the Gann Analyst program it is easily and automatically created for you on any chart in any time frame. The growth boxes give you both price targets and most important, time targets for the endings of bull and bear moves. If you CLICK HERE you will see several examples of the Jenkins Box technique as well as all the other tools developed by Mr. Jenkins.
