This indicator/tool (Auto Fibo) draws Fibonacci Retracement Levels automatically on any chart. The algorithm of the Indicator Plots the extreme points and puts the retracement levels in order by itself with 100% sensitivity. The key point is that to arrange the length of the "lookback bars" to arrange the correct extreme points. Like the other auto plotting tools, the levels can change when the time frame of the chart changes, in contrast with manually drawn Fibo levels.
