Chartists can add two extra Fibonacci numbers to the Fibonacci Retracements Tool using the CTRL button. First, open a SharpChart for annotation. The Fibonacci tools are at the top and in the middle of the icon row. Next, select the Fibonacci Retracements Tool and move to the desired starting point. Hold the CTRL button, left click the mouse at the starting point, hold that click and drag to the ending point. Release and two more Fibonacci numbers will appear: the 23.6% retracement and the 1.618% extension.

Using the US Dollar Index ($USD) as an example, the Fibonacci Retracements Tool extends from the January 2012 high to the May 2011 low. For drawing purposes, chartists need to start at the high and work backwards to the low. A 61.8% extension of this move would extend just above 87 and this level can be considered a Fibonacci target. MAC users should use the “Command” key instead of the CTRL key.
