Most brokers/share forum sites offer charts, but unless you pay, there's a 15min delay........!
I have heard of some, Money AM (I think), though that offers live chart data (FOC), but you'd have to sign up/open an account.........!
Google, will only update when a trade has been made, and charts actual trade value, rather than SP mid value, which is why it looks volatile sometimes.......!
All the best (look for brokers, with free live prices/charts is my advice, which I can't give, cos your not allowed to :)
