> Easy, trading cycles occur in (e.g.) ten second intervals synced to UTC atomic time. For instance results of trades propagated for five seconds, orders are accepted for five seconds and then are executed. This should allow enough time for reasonable latency and ensure that everyone has the most recent price on the exchange.

Right. But that would constitute a new type of trading -- similar to opening and closing auctions -- so it wouldn't be compatible with the current system.

But yes, it's definitely possible. The question is what the market prefers.
