Well, if your download process retrieves more than the current day's
quotes, then you would pick up the changes IF the changes are posted on
the free site. The purpose of the challenge is to compare different
sources to see what the range and magnitude of the errors is. I don't
think QM is the best solution for downloading a large number of tickers.
It is better for those who specialize on a market segment or the DJIA, or
who need to pull down a few tickers for analysis over a few years. In
those cases error correction by overwriting all of the data in a period
is not inefficient.
For all the talk re free vs. non-free, no one has answered the challenge
yet.
Cheers,
Jim
