andy_p... be careful.. With those kind of returns (assuming other metrics are ok like risk of ruin, standard deviation) , hedge funds would be throwing money at them... I would start with reading books from S Natenburg, L Macmillan first before going into advisory services. A good number of them advocate premium selling REGARDLESS of iv regime or regardless of ticker chart setups. (ex.. I would never sell premium near big numbers).The reason this method is prevalent is that they have a high win rate- which looks good on their site. The biggest problem is that when the method fails when markets convulse, they fail "bigly"....but by that time, they already have your $$$ and then move on to the next set of clients.
