Its all explained in the group files at <a href="http://finance.groups.yahoo.com/group/mvpsignalsystem/" target="_blank">http://finance.groups.yahoo.com/group/mvpsignalsystem/</a> Short answer all mvp trades are the 2X proshares mvv or mzz, piggybacks are short term margin excursions, usually 102 weeks then right back to cash. I think margin has a bad rep because newbies use it to buy high fliers at mkt tops. Then they get burned and pronounce margin as dangerous. That being said, I do think its better to get in and get out fast, rather than overstay the welcome. Each trade in the real-time file is cross referenced to the post which gave the signal before the market open.
