quote is a C++ library to get Yahoo! Finance data. It gets historical data and the latest quotes strings in csv format.
quote's Git repository is available on GitHub, which can be browsed at:
http://github.com/aphenriques/quote
and cloned with:
git clone git://github.com/aphenriques/quote.git
#include <iostream>
#include "quote.h"
int main(int argc, const char * argv[]) {
// all Yahoo! Finance quote types are implemented (this is just a sample)
std::string petr4Quotes = quote::getLatestQuotesCsv("petr4.sa", {quote::QuoteType::symbol,
quote::QuoteType::name,
quote::QuoteType::lastTradePriceOnly,
quote::QuoteType::lastTradeDate,
quote::QuoteType::lastTradeTime});
std::cout << petr4Quotes << std::endl;
// quote ranges can be daily, weekly, monthly, or dividends only
std::string petr4HistoricalPrices = quote::getHistoricalQuotesCsv("petr4.sa",
2014, 4, 2,
2014, 4, 7,
quote::RangeType::daily);
std::cout << petr4HistoricalPrices << std::endl;
return 0;
}
// prints:
// "PETR4.SA","PETROBRAS -PN",15.96,"4/22/2014","4:07pm"
// Date,Open,High,Low,Close,Volume,Adj Close
// 2014-04-07,15.70,16.46,15.70,16.46,50400200,16.46
// 2014-04-04,15.62,15.71,15.35,15.44,33173500,15.44
// 2014-04-03,15.53,15.65,15.12,15.40,56189100,15.40

quote is thread safe provided the following observation:
Manual curl initialization (curl_global_init) must be performed before using quote functions in a multi-threaded context, otherwise it can be ignored. Check http://curl.haxx.se/libcurl/c/curl_easy_init.html.
quote builds on Linux and MacOSX (Windows has not been tested yet). It requires a C++11 compatible compiler. The library has been successfully built with:
- Apple LLVM version 5.0; and
- gcc (Debian 4.7.2-5) 4.7.2
Modify common.mk for quote install configuration.
Any of the following make invocations can be executed with the -j option (make -j) for parallel compilation (builds faster).
To build the library:
$ make
The shared and static library files will be on src/ directory. The include files needed to use quote are on src/ directory.
To install:
$ sudo make install
To uninstall:
$ sudo make uninstall
To build the samples:
$ make samples
To clean everything compiled (including samples):
$ make clean
Set the compiler standard to C++11, include quote headers in the search path and link to its library. E.g:
compiler flags: `-std=c++11 -I/usr/local/quote`
linker flags: `-L/usr/local/lib -lquote`
Include the library header quote.h (namespace quote).
Check the samples directory for examples.
See doc/html/index.html for the doxygen generated quote API reference.
