It all boils down to whether the traders have an edge or not, and how frequently they trade. Some of these folks are making like 50 round-trips a day. Even with a slight edge, say 60% chance of a win on each trade, after that number of trades, the odds that you will have more winners than losers is up to 95%. With that type of chance you could literally go a month or two without a losing day!
For those of us who only make like two trades day (whether because we have a full time job, or simply have a different style), it is much more difficult to pull together a string of winning days even with the same probability per trade. That is just how things are. It is the law of large numbers at work. So there is no reason to doubt the performance.
If there is any criticism, it is that some folks show up only when there is a gain. It gives a very skewed and misleading picture.
