Thanks everyone for your warnings.
Unfortunately, being incompetent, I entrusted myself to the wrong people who pointed me to these sites.
A lot of things are happening on the internet. Either you use your head very well and avoid getting scammed, or scammers will use it for you and take what they can from you.
Never trust any guy who's on the other side of the screen trying to tell you an easy way to make money from a broker. If it's that easy, they won't have the time to start tutoring you on how to do it, as they will spend the rest of their time milking those brokers.
