Do trading signals work? If so, which is the best?
It is better to have a guide specially if you don't have enough knowledge in trading. Be more cautious and vigilant if you trade without a guide. Scammer is everywhere. It is best that seek help to those experts.
I know there are many channels that provide commercial signals on social networks and telegrams. The accuracy of these signals is relative to the intent of the person who created the signal channel to share or to benefit from those signals. So analyze and track the signals of several channels, then decide if you should invest or not.
