Hi Ladies n' Gents,

Given the availability of real-time stock quotes from GOOGLE (not yahoo), (reference http://www.google.com/googlefinance/disclaimer/ ) and the ability to query current live stock quote via...

Single symbol Quote:
http://finance.google.com/finance/info?client=ig&q=NASDAQ:GOOG

More than one symbols quote:
http://finance.google.com/finance/info?client=ig&q=NASDAQ:GOOG,NASDAQ:YHOO

and the resulting data which looks like this...
// [ { "id": "694653" ,"t" : "GOOG" ,"e" : "NASDAQ" ,"l" : "877.89" ,"l_cur" : "877.89" ,"s": "0" ,"ltt":"11:27AM

EDT" ,"lt" : "Jun 12, 11:27AM EDT" ,"c" : "-1.92" ,"cp" : "-0.22" ,"ccol" : "chr" } ,{ "id": "658890" ,"t" :

"YHOO" ,"e" : "NASDAQ" ,"l" : "26.30" ,"l_cur" : "26.30" ,"s": "0" ,"ltt":"11:28AM EDT" ,"lt" : "Jun 12, 11:28AM

EDT" ,"c" : "-0.10" ,"cp" : "-0.38" ,"ccol" : "chr" } ]

Question, if the query was for hundreds or thousands of stock symbol prices at once, what is the fastest way to

get the symbol's quote from the page???  Does it have to be reading each line one by one looking for the "t" ->

ticker and the last price "l_cur" ???  or is there a speed and efficiency trick that can be used???

Also anyone know how to get the official time stamp of the last price?  Meaning not the computers time or the

server query time but the exchange time stamp for the stick price to either the second or mili-second.

FYI:  Just trying to update prices as quickly as possible in my code.

Let me share my gracious thank you in advance.

Best - Dyno
