Moving averages are used to smooth trends. TC2000 offers four different types of moving averages.
A simple moving average gives equal weight to each data point for the period. If the period is 3 and the last three data points are 3, 4 and 5 the most recent average value would be (3+4+5)/3=4 (divide by three because there are three data points).
An exponential moving average (EMA), sometimes also called an exponentially weighted moving average (EWMA), applies weighting factors which decrease exponentially. The weighting for each older data point decreases exponentially, giving much more importance to recent observations while still not discarding older observations entirely
A front-weighted average, like an exponential average, allows the most recent data being averaged to impact the average value more than older data. It is calculated differently than exponential averages but it also gives recent data more weight. A 5 period front weighted average is calculated as follows (C is the most recent bar, C4 is 4 bars ago): Front Weighted Average = ((C5) + (C14) + (C23) + (C32) + C4) / 15
The Hull Moving Average solves the age old dilemma of making a moving average more responsive to current price activity whilst maintaining curve smoothness. In fact the HMA almost eliminates lag altogether and manages to improve smoothing at the same time...read more
You can see how the different averaging types produce different results. All four averages are plotted using a period of 21: simple (red), exponential (cyan), front-weighted (yellow) and Hull moving average (orange).
In addition, you can choose what element of price to use in the calculation of the average: Last, Open, High, Low, or Typical Price.
Offset Parameter Moving averages have an Offset parameter that allows you to shift the average plot forward or backwards (negative offset value). This allows you to plot what are commonly referred to as "displaced" moving averages. Read more about displaced moving averages on Investopedia.
