I am assuming you are a US citizen residing in the United States. The answer is a simple "no". You can become a prop trader which will require you to be "sponsored" by a properly registered broker and take and pass the Series 57 exam before placing any trades, but that is a whole different ballgame from your original question. First and foremost, I am on your side. If anybody says yes then they might be calling from Nigeria (the scam capital of the world) and you are basically asking someone to aid you in committing a felony. You will get caught. My recommendation would be to trade Forex with a "legitimate US registered broker". A 50X maximum leverage is gracious plenty to get yourself in trouble. I trade for a living full-time (profitably) now going on 20+ yrs. Please feel free to stay in touch. I have nothing to sell. Kind regards, HG https://www.linkedin.com/in/whenperformancecounts
