how you enter a position vs just a trigger

Hi Pat,  I'm new to your service.   Three part question: A.  When do you actually "buy" a position - would like some greater clarity on this. I notice couple "triggers" this morning, but you didn't buy? ( I saw a video where you correspond the stock buy with the corresponding ETF performance..?)   And when you buy, how do you let us know?  Is it "Buy Alert" on your twitter feed?  I've tried to find your buying methodology on your site but didn't see anything.  Maybe i'm missing something obvious. B. I noticed, you trimmed some of your FB yesterday as the stock was retrenching A.M. move up (thnx google).  But, today, it's back up and took out yesterday's high... Do you have rules for getting back in?   C. What are your criteria for Key list again?  I believe you said, % off high, and industry rank.   How do you narrow what i would think are many candidates down to your list?  I'm a MarketSmith (and Finviz) user too -  If there's material i can read (or view) on this, that would be great.  Thanks in advance.  Mike
