Well I can tell you why many wont be using them.They have an about the company on there page.
Windsor is an independent market maker and principal broker offering clients access to Foreign Exchange Markets covering major world currencies, Stock Indices including Nasdaq, Dow Jones and S&P 500 as well as Precious Metals , Futures (OTC) , CFDs and other commodities that are quoted on major world exchanges.
I think that should explain WHY no one would use them.
They just take your money, trade it against you make you lose.
They are not a real broker.Even there futures are unregulated cfd's.
Because if they were regulated they couldn't steal from people.
