They stold a $1000 from me. SCAMMERS!!!!!!

I was given promises prior to signing up. Soon as I signed, I was told the salesperson did not know what they were talking about. A lot of red flags is why I never opened my account In the process of disputing the charge as breech of contract and unable to perform as promised. use extreme caution as they state they provide software to hedge funds but the business is based out of a 2 bedroom house.
