I don't think so. If distance between NY and London is 10: Scenario A: you are 1 from NY, 9 from London. You will have information about time X from NY in X+1 and London in X+9. Your long to NY will take 1 and your short to London will take 9. That's a total of 18 to get quote and fill in London. Scenario B: you are 5 from NY, 5 from London. Total to get quote and get filled in both markets is equal at 10. The longest path is your latency in a simple long/short arbitrage situation, so being equidistant to all of your liquidity centers is advantageous.

Sorry but it's the speculators who made the profits today... The algo traders were the only ones that could keep up with the volatility. not all of them made money, but some sure as hell did.. No one gives a crap about the day traders, they're not the ones moving the money.
