Is there a web service to find the number of shares of a stock traded on different exchanges? For example, i would like to find the daily volumes of SPY traded on island, ARCA, etc. respectively. How can I do this? Help is appreciated.
I did some searching and could only come up with this site. They want to charge for access to the information though. http://www.archipelago.com/marketdata/hist_arcatrade.asp CajunSniper / Puretick.com Administrator-Trader
Sign up for Arcavision. I think it's still free. They have a stock volume tool that breaks down a stock's trading volume by venue.
