Someone else here said "random" for choosing which of two or more identical trades to execute. As it is now, it's "first one to arrive, measured in nanosecond time." I think the SEC decreeing "random" for trades within some time window (is the window of millisecond size? microsecond size? not sure) would be totally legit, and it would redirect financial resources to better trades, not faster ones.
