Going Long and Short on the same currency

Hello, first of all just want to say thank you all for the information provided on this site, it's been very valuable over the last few months as I have been back testing several strategies.
My question is has anyone here developed a strategy that involves buying and selling the same currency at the same time? I just spoke to my broker about this and they mentioned that it was illegal in the U.S., but I could open up two separate linked accounts. I've developed a solid strategy that is almost ready to start going live. I just want to see if anyone else has tried this or includes this in existing strategies.
Thanks!
Jacob
