If you are fan of Parabolic SAR you may know that this great exit tool is developed by J. Welles Wilder. It could really help you to build an effective trailing stop system. I have written an article that explains how to do that. Visit http://www.forexbrace.com/content/view/144/75/. You may even both enter and exit trades with Parabolic SAR. While I personally do not suggest that, I have developed a trading system based on a request I received from one my readers. Visit http://www.forexbrace.com/content/view/142/75/ for more information about this system. If you have any questions about these articles and/or Parabolic SAR I would be more than happy to answer.
