Is there some retail broker who would allow you to trade at more than one currency pair with exactly the same position i.e. instead of squaring the the position like

USD - gt; EUR USD,


I am able to execute

USD EUR JPY USD?

The brokers must allow us to do that. I can't understand why not...?
Its FX, thus we should be able to convert one currency to any other. That's the essence of the market, isn't it?


P.S. I have done my research to understand that trading in Arbitrage is banned by retail brokers. So that isn't my goal (though ideally I would really like to...I would really like to grasp that risk free money that is there all the time). However, I am guessing just the large banks and the hedge funds have the ability to accomplish that. (some comments are welcome...)
