Fibonacci Arcs are created on a chart by first drawing a trendline between two extreme points, a trough and opposing peak. Three arcs are generated that are centered on the second extreme point and intersect the trendline at Fibonacci Levels, usually of 38.2%, 50% and 61.8% of the distance between a price maximum and minimum.
