@ Restu Kasuandi:
From the official website of the broker VantageFx, the broker is regulated by VFSC (Vanuatu Financial Services Commission), so it is an offshore broker.
For the security of your trading and funds, we suggest choosing a broker that is already regulated by an internationally credible regulatory body, namely: CFTC, NFA, FCA, FSA, FINMA, MiFID, ASIC and FMA.
Credible regulatory bodies are those that have been tested and internationally recognized, and provide strict sanctions to brokers if they are found to violate agreed terms. These regulatory bodies are also responsible for the security of client funds.
