Code Challenge

Task Description

• View a list of currencies and the latest prices.
• Click a link and see the history of captured prices of a currency in descending order (by time).
• Capture the price of last, bid and ask.

Other points of interest:

• Allow for between 2 - 4 hours to complete this, however time is not important but rather quality.
• Tests.)
