www.fibotrader.com
is the site of Robert Fischer.
I believe he is the person who invented the use of Elipses in Trading.
According to Fischer, any 3 or 5 structure Elliot wave MUST be containable in a phi Ellipse. So By drawing a phi elipse to contain 2 sides of a wave, U can tell were the wave will end.
A phi-elipse is an elipse whose axis a:b have a phi ratio, when divided.
On the site Fischer has a charting package that auto-draws phi-elipses & phi-sphirals for you. It has a Free use version that runs on historical data.
Else U would need to print the charts and draw them yourself, as the scale must be kept fixed.
Fisher also has 2 books, the 2nd one :- Advanced Fibonnaci Strategies For Traders (available at Whileys), is a must read for anyone seriously relying on Fib Trading. Its also in the study currcuim for CMT & CFT students. And actually has its own test exercise book.
I can post U the link to purchase it - if yr interested, & its not already available on his site.
Take Care.
