It sounds suspicious to me, I have never heard about a broker without an spread. I recommend you do a research before you choose one, check if it is under regulation, and check what are they getting in return for you to use their platform.
If you let me I would recommend a broker with good and tight spreads for you to establish a point of comparison, it is tradeview, and they actually base their spreads depending on the pair which is good to me, so please evaluate your options before going with a determined broker.
I would recommend as I said the one that has given me excellent results about spreads, which is tradeviewforex. I understand they are regulated by the NFA and the CTFA, so give it a try, maybe it works for you as it worked for me. And if you have any questions you can chat with the support desk guys on the site. Trade well
I'm not sure why someone would want to risk going to an unknown broker, with no track record, only for something as unimportant as a pip or two on the spread. Some well known brokers have 0.9 pip Euro spread (Oanda) others are well capitalized and well known (FXCM). This game is one of "probabilities". What value do you seek in an unknown broker??
