NYSE physical floor volume

I have historical Nasdaq comp data that originates from MarketSmith. I currently do not have a MarketSmith subscription yet the system I work with uses MarketSmith data. I'd like to continue using MS data b/c the system is volume dependent. MarketSmith states "The data feed that is currently used by MarketSmith is called “NYSE Volume” and represents the volume transacted on the physical NYSE floor in New York." Is there a free way to obtain this data? Only looking for Nasdaq Comp H,L,C and volume daily data.
