Fibonacci Projections, or Fan Lines, are displayed by drawing a trendline between two extreme points, for example, a trough and opposing peak. Then an "invisible" vertical line is drawn through the second extreme point. Three trendlines are then drawn from the first extreme point so that they pass through the invisible vertical line at the Fibonacci levels of 23.6 %, 38.2 %, 50.0 %, 61.8 %, 76.4%, or whatever customized levels you prefer.

The keyboard can be used to move the Fibonacci points to the right and left. First, click on the chart. Then hit the tab key repeatedly until you notice your Fibonacci Projection lines are selected. Then, press the right or left arrow keys on your keyboard to move the entire Fibonacci line right or left one bar. If you would like to move only the endpoint, then hold down the Ctrl key while pressing the right or left arrow keys. If you would like to move only the beginning point, then hold down the Shift key while pressing the right or left arrow keys.
