Paid signals are usually premium signals, and I never use paid signals because of course the signals won't be accurate, even if the predictions are correct, it's just a coincidence. Because basically the signal only seeks profits from beginners who don't understand price movements, so they use it as a decision to take trading policies.

But even so, I often use free signals without paying, I don't do this to make decisions when trading, but I use trading signals only to use the signals as a comparison with existing news developments and with the results of independent research.
