Fibonacci Time Zones is a sequence of vertical lines
having Fibonacci intervals of 1, 2, 3, 5, 8, 13, 21, 34, etc.
Significant price changes are considered to be expected
near these lines.
To build this instrument, it is necessary to specify two
points to determine the length of a unit interval. All other
lines are built on base of this unit interval according to
Fibonacci Numbers.
