What leverage do they offer to retail clients?

IGFB is not a licensed or regulated broker even though it states offers that look good to be true. 

IGFB claims to be a reliable broker without presenting any information about its regulation. The lack of such important information may be a distinct signal of an unlicensed broker, as regulated brokers always present their accreditations and licenses in a prominent position. It is a red flag. 

IGFB also claims to be located in Dominica. But as per the information we hold, Dominica currently has no authorities that issue licenses for forex trading or regulate entities engaging in forex.

Moreover, both the Germany Federal Financial Supervisory Authority (BaFin) and the United Kingdom Financial Conduct Authority (FCA) issued warnings that IGFB is providing financial services or products without authorization. You can check the full warnings form BaFin and FCA.

The truth is, IGFB 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 IGFB and trade with licensed brokers.
