What is the difference between GARCH and ARCH?
Exponentially weighted moving average (EWMA) is an alternative model in a separate class of exponential smoothing models. As an alternative to GARCH modelling it has some attractive properties such as a greater weight upon more recent observations, but also drawbacks such as an arbitrary decay factor that introduces subjectivity into the estimation. GARCH(p, q) model specification. The lag len.
Moving averages act as a technical indicator to show you how a security’s price has moved, on average, over a certain period of time. Moving averages are often used to help highlight trends, spot trend reversals, and provide trade signals. There are several different types of moving averages, but they all create a single smooth line that can help show you which direction a price is moving.
Currently I use the EWMA model with the squared logarithmic returns as proxy estimator for the volatility, in order to forecast the volatility one step ahead in an intraday scenario (time frame is a.
Whether GARCH is your best choice is debatable. You could look at other sources to determine the volatility or, as an option 3, use EWMA on the data you already have to estimate volatility. I assume you want to do forecasts at some point.

The GARCH(1,1) is nested in the GJR(1,1) model, however, so you could use a likelihood ratio test to compare these models. Using AIC and BIC, the GARCH(1,1) model has slightly smaller (more negative) AIC and BIC values. Thus, the GARCH(1,1) model is the preferred model according to these criteria.
An exponential moving average (EMA), also known as an exponentially weighted moving average (EWMA), is a first-order infinite impulse response filter that applies weighting factors which decrease exponentially. The weighting for each older datum decreases exponentially, never reaching zero. The graph at right shows an example of the weight decrease. The EMA for a series Y may be calculated.

The GARCH model successfully captures the first property described above, but sometimes fails to capture the fat-tail property of financial data. This has lead to the use of non-normal distributions to better model the fat-tailed characteristic. Ever since Bollerslev introduced the GARCH model, new GARCH models have been.
Using exponentially weighted moving average (EWMA) charts Control charts are specialized time series plots, which assist in determining whether a process is in statistical control. By Keith M. Bower Some of the most widely-used form of control charts are X -R charts and Individuals charts. These are frequently referred to as “Shewhart” charts after the control charting pioneer Walter.
GARCH is a preferred method for finance professionals as it provides a more real-life estimate while predicting parameters such as volatility, prices and returns. GARCH(1,1) estimates volatility in a similar way to EWMA (i.e., by conditioning on new information) except that it adds a term for mean reversion. It says the series is “sticky.
