FXActivity

This graph plots relative price movement (the vertical scale) against relative "volatility" (the horizontal scale) over a particular time period. For information on how "volatility" is calculated, see below.

To choose the time period, click on the , , , or  buttons.

Choose from two versions of "volatility":

• Normalized, the volatility is a simple algorithm showing the difference between the maximum and minimum prices over the time period, divided by the minimum price (from the same time period).
• Historical, the volatility is a more complicated algorithm taking historical averages into account. Find out more.

To remove minor instruments from the chart, deselect the Show All check box.

How to read the graph

	The color of each instrument indicates activity:         Red – extraordinary activity         Green – moderate activity.
	Minor instruments are shown with greyed-out text. If an instrument doesn't appear in the graph, it has low volatility and low price movement (and falls within the elliptical shape surrounding the 0-0 origin). Hold the cursor close to the 0-0 origin to see a list of low-activity instruments.
	To see details and news events, hold the cursor over an instrument in the graph. If the details indicate there are FXNewsEffects for this instrument, click on the graph to open FXNewsEffects in a separate window.
	All instruments are shown in the list beside the graph on the right side. They are color-coded as follows:         Red, Green – the instrument is red or green on the current graph for the current time period (or would be red or green if all instruments were shown).         Black – the instrument is red or green for some other time period (for the normalized or historical graph you are viewing).         Grey – the instrument is not red or green for any other time period (for the normalized or historical graph you are viewing).

How volatility is calculated

The algorithms used for FXActivity provide different aspects of the concept of volatility.

Normalized volatility

The normalized volatility algorithm is a percentage of the difference between the maximum and minimum prices over the time period, divided by the minimum price. These values are always positive, and are a good representation of overall movement for the particular time period.

	Open price, Close price (at the start, end of the chosen time period)
	Highest (maximum) price, Lowest (minimum) price (during the chosen time period)
	Price movement (percentage)
	Normalized volatility movement (percentage)

Historical volatility

The historical volatility algorithm takes historical averages into account to minimize the effect of weekly market and announcement activities. Historical averages are calculated from snapshots taken at the same time interval over preceding weeks.

	Open price, Close price (at the start, end of the chosen time period)
	Highest (maximum) price, Lowest (minimum) price (during the chosen time period)
	Latest volatility (over the chosen time period)
	Average historical volatility (where N is a number of weekly snapshots)
	Price movement (percentage)
	Historical volatility movement (percentage)
