I wonder if the root of the issue could be addressed by making a requirement that valid stock transactions can only happen every 10 seconds. Transactions could be initiated any time, but the price of the stock would be finalized on transaction every N seconds. The intent to purchase (beginning of the transaction) could specify how many stocks to purchase and what is the maximum amount of money that could be spent for the transaction. A single service would need to be the authority of all transactions. I do not know much about how the stock market works, but I'd think that addressing the unfairness of computerized trading would not be an impossible thing to address.
