You take bids continuously but publish the bids and "resolve" the auction every X seconds, where X is between 5 and 10. Then there is no speed advantage as long as you can get your bid in within 5 seconds.
There is still a speed advantage. You can look at correlated markets for example and trade at the end of the time window with 5 seconds more info than anyone trading at the start of the time window.
