Why doesn't Equis data in

Security("\METASTOCK DATA\INDICES & INDICATORS\COMMON MARKET INDICATORS\X.NYSE-V",V);

match (or at least come close to) what's on the NYSE data site

http://www.nyse.com/marketinfo/datalib/1022221393023.html

For example, today (17 Sep 07) Equis has 1,107,618,300 but NYSE reports 2,714,975,000

MarketWatch reports 1,106,573,000 at http://www.marketwatch.com/tools/marketsummary/, while Yahoo Finance reports 2,636,274,000 at http://finance.yahoo.com/marketupdate/overview.
