Probably, but it wouldn't be a set sequence all the time.

Look at it as a Traveling Salesman problem, costs to move to each point, 
with the costs constantly changing. I once took a snapshot of the 
currency exchange rates and spotted an easy route, but it changed not 10 
seconds later (and it would have netted about 2 cents for every 1000 USD 
before fees). Throw enough computers at it, with enough money in each 
currency to make the moving easier, and who knows.
