STB Markets is not a regulated or licensed broker for traders even though it states offers that look good to be true.

STB Markets claims to be one of the largest CFD Trading brands while presenting no details about its regulations. Lacking regulatory information may be a distinct characteristic of unlicensed brokers, as legit brokers always present their certificates and licenses in a prominent position.

Besides, the Autorité des Marchés Financiers (AMF) issued a warning that STB Markets is an unauthorized firm. You can check the full warning from here.

The truth is, STB Markets 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 STB Markets and trade with licensed brokers.
