Research, not advice. This is what I found in public sources about prop trading firms. It is not financial advice or a recommendation to buy any challenge. A challenge is a paid evaluation: most people who try one do not get funded, and the fee is usually not returned. Rules, prices and ratings change often, so confirm everything on the firm’s official site. Some links here are affiliate links, explained in the affiliate disclosure. See the full disclaimer.
