@ Antono:
Based on the information we have, the broker Vonway Forex (Vonway Global Limited) is registered in the country of Saint Vincent and Grenadines, so it falls into the category of offshore brokers.
For the security of your trading and funds, we recommend choosing a broker that is already regulated by a credible international regulatory body, namely: CFTC, NFA, FCA, FSA, FINMA, MiFID, ASIC and FMA.
A credible regulatory body is one that has been tested and internationally recognized, and provides strict sanctions to brokers if they are found to violate agreed-upon terms. The regulatory body is also responsible for the security of client funds.
