That's the title for
this Reddit post.

In other news, on Monday I gave another lecture about stock-trading — or rather, about my inability to make any money at it. I described the extreme efforts I had to go through to compile an archive of 20,000 hours of trading in one particular stock-ticker (
IWM, an exchange-traded mutual fund that holds shares in the 2000 stocks that are just below the S&P 500). One person asked if I was going to "liberate" this data.
Yes I can! Unfortunately, intellectual-property licensing agreements prevent me from posting it here (I can give it out only to "a limited number of individuals", without charge, for noncommercial use, on an occasional and irregular basis). I tried posting the data to the Google Group for the programmer's meetup, but my message has gotten stuck in the queue. Please comment if you either want it or don't want it.
