Fibonacci
Retracements/Extensions are displayed by first drawing a trend line
between two extreme points. After selecting Fibonacci Retracement tool
from Draw toolbar, 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 (up or down), prices will
often rebound and retrace a significant portion of the original move. As
the price retraces, support and resistance levels will often occur near
the Fibonacci Retracement levels.
