I prefer not to have targets and let my trades run untill proven differently by price action. However I do use a disaster stop which is volatility based.
An example: my most recent bullish swing trade in gold http://localsfoolsgold.blogspot.be/2013/11/this-is-what-multi-week-bottom-looks.html and how I am attaching a disaster stop to it: http://localsfoolsgold.blogspot.be/2013/11/overlooking-things-and-volatility-based.html all in all pretty simple stuff. Good trading doesn't need to be difficult.

I'd work somehow along the same lines as described above ...
