These words are extremely powerful. You will get plenty of ideas from ET if you have the patience to sift through all of the BS. But you need to develop your own strat based on your own personality. Conversely, I tried reading through the AHG thread months ago, but didn't have the patience. I'm not saying there is not any validity to it. Just wasn't for me. Sorry. Kind of off topic, but my answer is no, although I never had any real reason to try it.
This thread has links to previous AHG threads. Enjoy. http://www.elitetrader.com/vb/showthread.php?s=&threadid=145782&highlight=ahg
