I thought that it was probably based on moving averages. But it is not always easy to find a combination of moving averages that work. They do want a lot of money for it. They offer it on sale for $3K.
Another thing I feel is going for the software is the growing user base. When a bunch of people see a stock (say XYZ), with all green lights, and they rush to buy it (regardless of whether there is indeed a technical basis for it), that's gonna move the stock regardless.
Kinda like that old CNBC effect in prior years.
