Exponential Smoothing
A mathematical-statistical method of forecasting that assumes future price action is a weighted average of past periods; a mathematic series in which greater weight is given to more recent price action.

**Exponential Smoothing
Some observant readers have questioned why Step 3 is not divided by 21 days, to create an exponential moving average. The same applies to Step 4.
You will note that Step 5 divides the result of Step 3 by Step 4.
TRIX - Triple Exponential Smoothing Oscillator
Ultimate Oscillator
Upside/Downside ...
Single linear exponential smoothing was developed in the early 1950s as a means of prediction along a straight line whose slope was based on previous data.
Its triple exponential smoothing is designed to filter out insignificant cycles. Trades should be placed when the indicator changes direction (i.e., buy when it turns up and sell when it turns down). The TRIX can also help identify turning points.
Equation (1) implicitly includes the exponential smoothing: If K = 0.2, (number of periods is 9) and EMAt-1 = 10, it follows that a current price of Pt = 12 leads to an EMAt = 10.4, a price Pt = 8 leads to EMAt = 9.
The TRIX indicator oscillates around a zero line. Its triple exponential smoothing is designed to filter out "insignificant" cycles (i.e., those that are shorter than the number of periods you specify).
Insignificant cycles are excluded by using triple exponential smoothing. It's able to lead a market as it calculates the distinction between each bar's smoothed version of the price information.
choose the "Morris Modified" option in the preferences, the average loss and average gain will only be computed over the Period specified (Simple Smoothing), otherwise ("Morris Modified" unchecked), the averages are cumulative (Exponential Smoothing).
TRIN See Arms Index Trix-The one-period difference of the triple exponential smoothing operating on the log of price.
Like other oscillators, TRIX oscillates around a zero line. Its triple exponential smoothing makes it an excellent filter of market noise and it functions well as a leading indicator of market trends.
It uses two exponential moving averages smoothed as a means of comparison to see whether a currency is heading towards an increase or a decrease.
This "exponential smoothing" to avoid any distortion from unwanted noise or spikes.
This is a momentum indicator. It is the percent of the rate of change of a triple exponential smoothing of stock's price. A signal line is an EMA of the main line.
In this article Mulloy says:
"Moving averages have a detrimental lag time that increases as the moving average length increases. The solution is a modified version of exponential smoothing with less lag time.."
