Leonardo Fibonacci was an important mathematician who was born in Italy around the year 1170. It is rumored that Fibonacci discovered the relationship of what are now referred to as Fibonacci numbers while studying the Great Pyramid of Giza in Egypt.
Fibonacci numbers are a sequence of numbers in which each successive number is the sum of the two previous numbers:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, etc.
These numbers possess an intriguing number of interrelationships, such as the fact that any given number is approximately 1.618 times the preceding number and any given number is approximately 0.618 times the following number. The booklet Understanding Fibonacci Numbers by Edward Dobson (see Suggested Reading) contains a good discussion of these interrelationships.
See Drawing a Line Study for more information on drawing line studies. See Fibonacci Arcs (Fibonacci Arcs), Fibonacci Fans (
Fibonacci Fans), Fibonacci Retracements (Fibonacci Retracements), and Fibonacci Time Zones (Fibonacci Time Zones) for more information on the Fibonacci parameters.
Retracements
Fibonacci Retracements are displayed by first drawing a trendline between two extreme points (i.e., a significant trough and peak). After selecting Fibonacci Retracement from the Insert menu, a series of up to nine horizontal lines will be drawn at the Fibonacci levels of 0.0%, 23.6%, 38.2%, 50.0%, 61.8%, 100%, 161.8%, 261.8%, and 423.6%.
After a significant move (either up or down), prices will often rebound and retrace a significant portion (if not all) of the original move. As the price retraces, support and resistance levels will often occur at or near the Fibonacci Retracement levels.
Fans
Fibonacci Fan Lines are displayed by first drawing a trendline between two extreme points. MetaStock then draws an invisible vertical line through the second extreme point. This vertical line is then divided at the Fibonacci levels of 38.2%, 50.0%, and 61.8%. Finally, three trendlines are drawn from the first extreme point so they pass through the invisible vertical line at the above three levels. (This technique is similar to the method used to calculate Speed Resistance Lines, see Speed Resistance Lines.)
Arcs
The calculation and interpretation of Fibonacci Arcs is similar to that of Fibonacci Fan Lines. First, a trendline is drawn between two extreme points. MetaStock then draws three arcs, centered on the second extreme point, that intersect the trendline drawn between the two extreme points at the Fibonacci levels of 38.2%, 50.0%, and 61.8%.
The interpretation of Fibonacci Arcs involves looking for, or anticipating, support and resistance as prices approach the arcs. A common technique is to display both Fibonacci Arcs and Fibonacci Fan Lines and to anticipate support/resistance at the points where the Fibonacci studies cross.
The points where the Arcs cross the price data will vary depending on the scaling, because the Arcs are drawn so they always appear circular relative to the computer screen.
Time Zones
The Fibonacci Time Zones command displays vertical lines at the Fibonacci intervals of 1, 2, 3, 5, 8, 13, 21, 34, etc. The interpretation of Fibonacci Time Zones involves looking for significant changes in price near the vertical lines.
