I've been doing "paper trades" since 2007. I've taken about 5 years off. I've probably made, on average, 5 paper trades per trading day. I would regularly predict not only massive moves but also exact tops and bottoms and the pathways in between. I would estimate at least 1 out of 5 options trades was worth at least 200% but many many other typical trades were worth several times more than that. I also traded options with at least a projected volume of 80X my own trade. What I found was that an extreme familiarity with subtleties and nuanced behaviors of individual stocks plus a host of many other clues pointing to the same conclusion would almost guarantee success every time . My win rate combined with my profits compared to my losses almost guaranteed that no losing streak would ever wipe me out .
