Because they operate on the most current information available about the market, they know exactly what to expect from the market. This is important because most stock market prediction software is based on the fact that there are six major markets with their timing mechanism, and that the stock market predictors try to take advantage of the highs and lows of each market to maximize their profits.
Another reason they are highly regarded is because of their accuracy. There are many programs out there that will tell you that they can make money in the stock market. The problem is, is that many of them aren't very good. But except for those which are scams, the programs which are highly regarded are the real thing. Stock market prediction software knows exactly what to expect from the market and has been consistently accurate in the past.
