This library provides some methods that should make it easy to communicate with the Yahoo Finance API. It allows you to request detailed information, some statistics and historical quotes on stocks. Separate functionality is available to request a simple FX quote. Please check the javadoc (available in dist directory) to get a complete overview of the available methods and to get an idea of which data is available from Yahoo Finance.

#Examples ##Single stock

Stock stock = YahooFinance.get("INTC");

BigDecimal price = stock.getQuote().getPrice();
BigDecimal change = stock.getQuote().getChangeInPercent();
BigDecimal peg = stock.getStats().getPeg();
BigDecimal dividend = stock.getDividend().getAnnualYieldPercent();

stock.print();

Output:

INTC
--------------------------------
symbol: INTC
name: Intel Corporation
currency: USD
stockExchange: NasdaqNM
quote: Ask: 32.25, Bid: 32.24, Price: 32.2485, Prev close: 33.62
stats: EPS: 2.019, PE: 16.65, PEG: 1.74
dividend: Pay date: Mon Dec 01 06:00:00 CET 2014, Ex date: Tue Aug 05 06:00:00 CEST 2014, Annual yield: 2.68%
history: null
--------------------------------

##Single stock, easy refresh

Stock stock = YahooFinance.get("INTC");
double price = stock.getQuote(true).getPrice();

This will also automatically refresh the statistics and dividend data of the stock in a single request to Yahoo Finance. Please be aware that it wouldn't be a good idea to call the getQuote(true), getStats(true) or getDividend(true) too much in a short timespan as this will cost too much delay without providing any added value. There's no problem to call the versions of those methods without argument or with the argument set to false.

##Multiple stocks at once

String[] symbols = new String[] {"INTC", "BABA", "TSLA", "AIR.PA", "YHOO"};
Map<String, Stock> stocks = YahooFinance.get(symbols); // single request
Stock intel = stocks.get("INTC");
Stock airbus = stocks.get("AIR.PA");

##FX quote

FxQuote usdeur = YahooFinance.getFx(FxSymbols.USDEUR);
FxQuote usdgbp = YahooFinance.getFx("USDGBP=X");
System.out.println(usdeur);
System.out.println(usdgbp);

Output:

USDEUR=X: 0.7842
USDGBP=X: 0.6253

##Single stock, include historical quotes (1)

Stock tesla = YahooFinance.get("TSLA", true);
System.out.println(tesla.getHistory());

Output: (Symbol@Date: low-high, open->close (adjusted close))

[TSLA@2014-10-01: 217.32-265.54, 242.2->229.7 (229.7), TSLA@2014-09-02: 240.12-291.42, 275.5->242.68 (242.68), ...]

##Single stock, include historical quotes (2)

Calendar from = Calendar.getInstance();
Calendar to = Calendar.getInstance();
from.add(Calendar.YEAR, -5); // from 5 years ago

Stock google = YahooFinance.get("GOOG", from, to, Interval.WEEKLY);

##Multiple stocks, include historical quotes

String[] symbols = new String[] {"INTC", "BABA", "TSLA", "AIR.PA", "YHOO"};
// Can also be done with explicit from, to and Interval parameters
Map<String, Stock> stocks = YahooFinance.get(symbols, true);
Stock intel = stocks.get("INTC");
Stock airbus = stocks.get("AIR.PA");

##Alternatives for historical quotes If the historical quotes are not yet available, the getHistory() method will automatically send a new request to Yahoo Finance.

Stock google = YahooFinance.get("GOOG");
List<HistoricalQuote> googleHistQuotes = google.getHistory();

Or you could explicitly define the from, to and Interval parameters to force a new request. Check the javadoc for more variations on the getHistory method

Calendar from = Calendar.getInstance();
Calendar to = Calendar.getInstance();
from.add(Calendar.YEAR, -1); // from 1 year ago

Stock google = YahooFinance.get("GOOG");
List<HistoricalQuote> googleHistQuotes = google.getHistory(from, to, Interval.DAILY);
// googleHistQuotes is the same as google.getHistory() at this point
// provide some parameters to the getHistory method to send a new request to Yahoo Finance
