How many should I pay to open an account?

Margex is not a licensed or regulated broker even though it states offers that look good to be true. Margex claims to be operated by Margex Trading Solutions Ltd, a company incorporated under the International Business Companies Act of 1994 of the Republic of Seychelles, with a company number of 225155. However, having registration does not mean having regulations by any regulators. We did not find any match results to Margex Trading Solutions Ltd in the Seychelles Financial Services Authority (Seychelles FSA). 

More importantly, the National Securities Market Commission (CNMV) issued a warning that this firm has not been authorized to provide financial investments and services. You can check the full warning from here.

The truth is, Margex is not overseen by any regulators. That means your personal data or your funds in this broker are unsafe and cannot be protected by any law. We would recommend traders stay away from unregulated brokers like Margex and trade with licensed brokers.
