comment Why C is still in use especially in area of numerical optimization (instead of C++)?
Feel free to close it. There is no value-added; same question has been asked a bazillion times already...

I think I disagree with this assertion. C++ projects like Boost, Eigen, Armadillo, half a dozen ML libraries, ... all do very well with C++ interfaces. And if you must, you can always use a C interface for glue (as eg offered by R and used by Rcpp).

comment Is there a piratebay for data(bases)? (here, talking about historical financial data)
+1 for mentioning both billion dollar business and some free (but generally delayed access) accessor functions. I have been standing the corresponding Perl / CPAN package Finance::YahooQuote for longer than I care to admit too :)

comment What is a commonly accepted econometric model for volume?
As an aside, GARCH models volatility (i.e. second moment), not price (first moment).

comment R: How feasible is it to store — and work with — tick data in a database connected to R?
The beancounter package has been available since the late 1990s to download price data, automatically store it in SQL backends with support for PostgreSQL, MySQL, SQLite and ODBC, and also run P/L and risk (VaR) reports. Runs just fine as a cron job, and its easy to then chain R jobs onto it once the data is in SQL. Beancounter itself is a small Perl package and runs on any OS just fine.

comment R: How feasible is it to store — and work with — tick data in a database connected to R?
ODBC will always be slower than direct binary connections, so it is really just the fallback choice. I once built a direct R bridge to OneTick using their C++ API -- that was pretty fast for large data too.
