Quote from bignatty:
Not sure. This whole strategy is similar to using margin to buy yield bonds of REITS. It can make money, BUT is can collapse very quickly. High reward means high risk. There is no free lunch. FX market is the most liquid in the world, CTA's would be making a bundle off of these if it were as risk free as you suggest. If your pairs get even 5% out of whack at 50:1 margin thats 250%!!!!. Interest can only make up for so much of a drawdown. Think about the high yield bond, REIT margin example.
