Did anyone see the Da Vinci code this weekend?? I did! No,  I have not read the book, but every time I got on an airplane the past 2 years  there was always someone reading this book!
Did you notice the references  to Fibonacci all over the movie? I did, and was counting the sequence right  along with John Langdon (aka Tom Hanks)! That got me thinking a little more  about one of my favorite trading tools and what it all means. So I went hunting  for some facts and this is what I found.
Leonardo Fibonacci was the  Italian mathematician who was born around the year 1170 AD. His real name was  Leonardo Pisano, but was better known by his nickname Fibonacci (“son of  Bonnacci”). Fibonacci’s father was a diplomat and his son traveled with him  during his formidable years studying mathematics and accounting.
In 1202,  Fibonacci wrote Libre Abaci, a book about the mathematics he had learned on the  road with his father. That book led to his famous number sequencing when  measuring the ratios for which rabbits reproduce.
His sequence  0,1,1,2,3,5,8,13,21,34,55,… is that each number is the sum of the two preceding  numbers. The interesting thing is that each of the successive numbers is equal  to 1.168 of the prior number.
Check this out!
When looking at this  geometrically you find that when you measure a triangle by 1.00 as the  hypotenuse the opposing side ratios are .786 and .618. Hey, I have seen those  ratios before!
When we make .786 the hypotenuse than the opposing side  ratios are .618 and .486. No way!!
If we make .618 the hypotenuse then  the opposing side ratios are .486 and .382. Right on!!
The Fibonacci  ratios that I always focus on in my trading  are:
Retracements:
38.2%
50.0%
61.8%
78.6%
Extensions  and Expansion:
61.8%
100%
127% (note that INDU turned almost on this  extension last week!!)
162%
Want some more or have you had enough? I  thought you would want one more example of FIBOs in nature!
Look at your  own hand:
You have...
2 hands each of which has ...
5 fingers, each of  which has ...
3 parts separated by ...
2 knuckles
All Fibonacci  numbers! How about this, the bones in your finger are all in Fibonacci ratios to  each other too! Is this just a coincidence or not??
OK, OK I think I just  gave everyone a headache. You are all probably thinking that I need to get away  from my trade station more often! Bottom line is that you don’t really need to  know the details of Fibonacci’s life or all the examples in nature.
The  bottom line is that we all know how important these ratios are to our trading  and it will pay huge dividends to learn how to apply these principals to our  trading!!
