Scam. A sham and a useless waste of $900. Basically using keltner channels to anticipate pullbacks and gain an "edge." DOES NOT WORK- no better than rolling dice. STAY AWAY. When I called the author to ask what the ratios would be if you traded the YM instead of ES, he said he really couldnt answer that question. What?? And this is supposed to be an expert?? Draw your own conclusions.
