Seasonal Indices are a compilation of daily seasonal values for individual commodities. A seasonal index rating is calculated for each of the average 251 trading days per year using the vast data resources that are provided with Unfair Advantage. Some of the resulting indices are virtually mirror images of the recent past, while others reflect only subtle seasonal effects. Seasonal indices offer a way to combine seasonal information on commodity data with daily chart analysis to promote a better understanding of price movement.
The seasonal index represents a + or - 3 sigma confidence interval over time. It reflects and reports upon the entire history of the series given as input in a cumulative manner. In the non-amplified form, the index is painted a day at a time as more input contributes to the seasonal pattern. The index may become more and more dampened as more information is supplied. There is no attempt to use the final year in the seasonal waveform to explain the past. In other words, the seasonal wave for of, say, a ten to 20 year series can be used as an input to forecast future events or simulate past events without bias where any then-current reading does not and cannot affect earlier seasonal patterns. Improved results may appear when longer term computed input is prepared using the "detrend" option.
To add Seasonal Index data as a study to any continuous price series, simply make a daily chart of the underlying market, click the "Indicator" button on the toolbar, and select "Seasonal Index."
Alternately, pull down the Chart menu, click "Study Toolbar" and then select "Seasonal Index."
Amplify:
The only user-defined parameter in the seasonal index computation is amplification. This makes the seasonal waveform easier to conceptualize and amplifies seasonal effects. Unfortunately, by selecting amplification, the significance of the seasonal effects will be distorted because the measured significance of the sigma readings will be lost.
Here is an example of a Seasonal Index chart drawn from the detrended live cattle series (Upper Chart).
Don't attempt a seasonal index calculation unless your input time series holds more than one full year of data. When years of substantial history are supplied, the cumulative general waveform tends to prevail all of the time. The resulting waveform becomes more and more characteristic of the commodity as more data is processed. We recommend this study be performed on at least ten years of daily (not weekly or monthly) data. If a computed contract is used as input, it must not contain ANY negative values.
The suggested usage of seasonal indices is to look for coincident peaks and troughs between the market and the index. When peaks coincide or when troughs coincide, the risk of loss on a trading position should be at its minimum. For some traders this may translate into an opportunity to take a heavier position. It is not recommended that seasonal indices be used as the sole basis for trading. They should only be used in conjunction with other confirming market factors.
Seasonal rainfall refers to the pattern of precipitation that occurs during specific times of the year in a particular region. It can vary in intensity and duration, impacting the local climate, vegetation, and agriculture. Understanding seasonal rainfall patterns is crucial for predicting flooding, droughts, and overall water availability.
Seasonal patterns refer to trends or changes that occur regularly at specific times of the year. These patterns can be observed in various phenomena such as sales data, weather patterns, or consumer behavior. Understanding seasonal patterns can help businesses and individuals anticipate changes and make more informed decisions.
Seasonal cycle
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
Seasonal changes refer to the variations in weather and environmental conditions that occur at regular intervals throughout the year. These changes are typically driven by the Earth's tilt and its orbit around the sun, resulting in differences in temperature, precipitation, and daylight hours. Examples include the transition from winter to spring, and summer to fall.

Daily - One a day. Seasonal - One a season, or 4 times a year.
Non seasonal flowering could mean two things: The plant is flowering outside of its normal flowering period. For example where Chrysanthemums are "forced" to flower outside of summer. Another meaning could be with respect to the term "seasonal"; annual plants are sometimes called seasonal, so non-seasonal plant could mean that its a perennial plant.
