Currency Graph Quick Start
Choose your currency pair
Use the top left drop-down menu to choose the currency pair (for example, EUR/USD or USD/CAD):
To choose which pairs are available in this list, go to Tools > User Preferences > Rates.
Set time period granularity
The purpose of using different time periods is to focus on short-term vs. long-term trends. To set the time period granularity shown on the graph, use the second drop-down menu at the top left:
Choose from a time period granularity ranging from 5 seconds (the finest granularity, which graphs prices for roughly the last 40 minutes), to 1 month (the largest granularity, which graphs prices for roughly three years).
Specify the graph type
Use the third drop-down menu from the left to choose the type of line that's plotted on the graph.
