    $\begingroup$ Where could I download data for Advance-Decline-Unchanged issues for NYSE, AMEX and NASDAQ as far back in history as possible (NYSE data starts in March 1965, AMEX data starts in February 2002, NASDAQ data starts in January 1978.) The best resource for download I was able to find until now is unicorn.us.com/advdec which is really great. Unfortunately with data only from 2002. I am looking for NYSE Up/Dn Issues and volume since 1965. Thanks for any hints where to get this. $\endgroup$
