The Nordea Gem
==============
[](https://travis-ci.org/matiaskorhonen/nordea) [](https://codeclimate.com/github/k33l0r/nordea) [](http://badge.fury.io/rb/nordea)
Exchange rates from Nordea Bank.
Installation
------------
Just like any other gem:
gem install nordea
Usage
-----
### With the Money gem
The Money gem integration works in a similar way to the [eu\_central\_bank](https://github.com/RubyMoney/eu_central_bank) library, mostly because I referenced that gem while building this one. A couple of the methods in the Nordea::Bank class are pretty much identical to those in the eu\_central\_bank gem.
nordea_bank = Nordea::Bank.new
Money.default_bank = nordea_bank
# Exchange 100 EUR to USD
nordea_bank.exchange(100, "EUR", "USD")
# Exchange 100 USD to South African rands
Money.us_dollar(100).exchange_to("ZAR")
# Exchange 100 Canadian dollars to US dollars
nordea_bank.exchange_with(Money.new(100, "CAD"), "USD")
# Update the forex rates
nordea_bank.update_rates
### Without the Money gem
exchange_rates = Nordea::ExchangeRates.new
exchange_rates.currencies
#=> returns a hash of currencies
exchange_rates.currencies(true)
#=> returns a hash of currencies, but forces a data update
exchange_rates.headers
#=> returns a hash of the data headers from Nordea
For more information, read the [documentation](http://rubydoc.info/gems/nordea).
Ruby compatibility
------------------
The gem should work with Ruby 1.9.3, Ruby 2.0.0, jRuby, and Rubinius (only Ruby 1.9 is actively targetted).
About the data and data source
------------------------------
Nordea quotes exchange rates on national banking days at least three times a day:
* in the morning at 8.00,
* at noon at 12.15 and
* in the afternoon at 16.15 (approximate times).
