Hi RUDEBOY
are you talking about trend lines and fibonnaci retracement lines?
A trendline is a sloping line that is drawn between 2 or more prominent points on a chart. Rising trends are defined by a trendline that is drawn between two or more troughs (low points) to identify price support. Falling trends are defined by a trendline drawn between two or more peaks (high points) to identify price resistance.
Fibonnaci retracements lines are displayed by drawing a trendline between two extreme points. For example, a trough and an opposing peak. A series of 9 horizantal lines are added to the chart intersecting the trendline at the various fibonnacci levels. Although many charting applications will only display the 38.2%, 50.0% and 61.8% retracement levels on the chart.
