As for me, I do not use signal because I know that the signal providers are only looking for ways to enrish their own pocket and nothing more.
If a trader follow the right thing to do in trading and not greedy, he will make money from it.
I definitely agree with you.
Trading using signals from signal providers are not profitable in the long run.
Because if suddenly the trading signal providers just stopped their service, the profit will also stop to those who are availing their service most of the time. Self study is the best because the knowledge will be engraved in your brain forever, no fees or whatsoever. Being independent is so much better rather than trusting your future to other people.
