Hi Mark,
Currently with the Google Historical (mutual) quote server, if we want to download all of the historical prices available, we have to do multiples queries with the limit of 180 days. Could it be possible that the quote module handle the multiples queries itself, with the aim of downloading, for example, 10 years of prices with only one user query ?
By the way, the downloads with the new quote servers Wall Street Journal, Quandl and FondChecks work great, it's awesome.
