According to this source, stock scanners are source becoming one of the most popular ways for people to pick and choose the stocks that they are trying to purchase so that they can sell them off at a later date for a price that is higher than what they managed to pay thereby making a profit that would be worthy of their efforts all in all. However, there is a mistake that people make when they use scanners like this, a mistake that could prove to be very costly indeed if you are not careful about the manner in which you could potentially end up making it.
This mistake involves overusing scanners. While it is perfectly understandable that you would rely on scanners while you are new to this sort of thing, the whole point is to build your skillset up to a point where it would be capable of handling things on its own. You need to become self sufficient and self reliant when you are working in the field of stock trading, and the most efficient way to do so is to try and develop your own instincts so that you can trade stocks based on these instincts and figure out a way to make the stocks you are looking into provide newer and better ways to get the most out of things in every single way.
When it comes to sock scanners they have a tendency to become a bit of a crutch which is why you should try to avoid using them too often and instead attempt to build some kind of repertoire of intuitive skills which is what you are going to be relying on in the future instead of the various stock scanners that people tend to use.
