Many sites that sell signals are not profitable, their subscriptions are very expensive, and for the most part they only apply technical analysis and not a logical market analysis following some theory, so many signals frequently fail.  The best thing you can do is allocate that money you are willing to use in trading signals using your own criteria, many signal sellers are quite smoke sellers. If they were profitable they would not sell signals.

As already mentioned, in the forum you can find many points of view of technical analysis and opinions of many people who have a lot of experience, you can read the tips they offer and you get much more rich and the learning process is done much faster .
