IMO All that Forex Signal sellers are trying to sell an account at their favorite Broker to get some Promotion.
If you want to learn trading, make your own research. It´s not that complicated.
Every broker offers free courses. With that in mind you could do your own research and dig more in trading.
As i said, i never saw a legitimate signal trader.
Yes but a friend of mine is making a good money using Forex signals from telegram groups. He said that he has never been scammed.
