Seasonality Chart

Overview


By definition, Seasonality is a characteristic of a time series in which the data experiences regular and predictable changes which recur every calendar year. Any predictable change or pattern in a time series that recurs or repeats can be said to be seasonal.

The Seasonality chart is a method of identifying these seasonal patterns visually, and while this chart style is commonly utilised for futures markets, the theory behind Seasonality charts can be applied to any code in Optuma (Stocks, FX, etc).


To create a chart, click on New > Single Code Chart > Seasonality Chart and enter the code of the required instrument. There are a number of display options under the Draw Style property, and also to compare user-defined years.

Bar Style

Displays the average of each time period in discrete bars. Here's an example of Heating Oil futures (HOSpot) with the blue diamond showing the current measure:


Component Style

Shows each year as a discrete line for each period, either in absolute, actual, or percentage terms.



Box & Whisker Style



Comparison Style: Compare Years

By changing the Comparison Style property from Seasonality to Compare Years you can enter specific years to compare. Here's an example of SPX performance for the last 10 US presidential inauguration years:
