Wow, what an enlightening discussion. None of you managed to answer the guys question.
Yes cash-futures arbitrage does exist in the FX space. No there is no such thing as pure arb opportunities as defined by investopedia, but High Frequency Trading Firms like mine manage to do pretty damn well on 1 pip / several microsecond trades.
I don't need to list the names of firms that do this. If they hire Ph.d's from MIT and spend 30 Million on infrastructure then they probably do some form of c/f arb type strats. Its almost 2012 now and we're still making money off this stuff.
