I learned the most about FROs or Fixed Return Options from this site: http://www.tradeking.com/PublicView/home/promo/FRO/FROone001.tmpl http://www.tradeking.com/PublicView/home/promo/FRO/FROone001.tmpl Download the white paper and, WOW, it explains everything about Fixed Return Options or Binary Options...
www.eztrader.com Binary options - slightly better odds than described by the FRO, since you get a precentage of the investment even upon unsuccessful bid.
