look at bid and ask just below the title "real-time best bid & ask". You can also see the level II info showing market makers' bid/ask stack as well as size on bid/ask.
The big price number and volume is 20 mins delayed just like everyone else, but you can tell where the stock is by the real time bid/ask info. You can confirm this by writing down the bid/ask numbers at 4:01 pm, and then compare that with where the final price is on the 20 min delayed basis.
Sentiment: Strong Buy
Yes, I just noticed that recently and it does seem to reflect the live 'actual' price. Just strikes me as strange not to quote the price based on realtime bid and ask, as its the bid/ask figures that define the price anyway...
