Virtually any consumer can get true real-time trading data if they're willing
to pay some relatively modest fees for that access -- Last I knew, the most
expensive 'real-time' fee charged by any exchange was under $200/mo.  For
everything traded on that exchange.  For anybody doing short-term, 'tactical',
trading, that is a "petty cash" expense.

Imposing the 15-minute delay on 'everybody', would simply give the 'floor
traders' the -exclusive' edge on those trading strategies.
