XtreamForex is a non-regulated broker that we advise against trading with, despite the seemingly attractive deals it offers.

XtreamForex claims to be a Brand Name of Xtream Markets Ltd, a company registered with the Marshall Islands Registry (IRI) under registration number 84516. Although we did find records matching this broker in the registry of the IRI, it's important to note that the IRI neither issues forex licenses nor regulates entities engaged in forex activities. In essence, XtreamForex is not subject to any valid regulations.

Regarding your question, we strongly advise against dealing with XtreamForex since there are no legal protections in place to protect the funds you entrust it to hold and control. Trading with it is highly risky. As a result, we suggest investors avoid unlicensed brokers like XtreamForex and opt for fully regulated ones instead.
