I have been paper trading some trades from stockoptioninvesting.com and they've done pretty well so far. I emailed them and they told me that they started out 3 years ago with $100,000 and now they have roughly $5,000,000 in their account today. Should I be skeptical about this? I've gone through their site quite a bit, looked at their past performance, and I've noticed that they are only about 50/50 (W/L) most of the time. However, their strategy seems to work well enough to pretty much double their money (each month of trading) by using trailing stops to limit losses and make upside potential almost unlimited. I've always heard that if something sounds too good to be true that it isn't but this seems pretty believable to me. What do you guys think? If this service is bogus, do you know of one or more that aren't?
