A lack of clear information is one of the first things that would make me cautious about a broker. When comparing best forex brokers I would watch for unclear fees, vague withdrawal rules, missing licensing details, unexplained trading conditions, or terms that are difficult to understand. I also think inconsistent information across different pages can be a warning sign. Checking independent reviews, regulatory updates, and recent broker news can help verify what a company actually offers. For me, transparent terms and straightforward communication are essential when assessing a broker.
