  • In the graph above, the dashed, red line represents a 90-day simple moving average.
  • The default choice for the average is a simple moving average, but other types of averages can be employed as needed.
  • If the data used are not centered around the mean, a simple moving average lags behind the latest datum point by half the sample width.
  • The DPO is calculated by subtracting the simple moving average over an " n " day period and shifted n / 2 + 1 days back from the price.
  • The CCI is calculated as the difference between the typical price of a commodity and its simple moving average, divided by the mean absolute deviation of the typical price.
  • Unlike some other smoothing methods, such as the simple moving average, this technique does not require any minimum number of observations to be made before it begins to produce results.
  • This is in contrast to a simple moving average, in which some samples can be skipped without as much loss of information due to the constant weighting of samples within the average.
  • The Hacker's diet does explain how to compensate for the lag in the results from a simple moving average-and it also tweaks the approach by putting more weight on the more recent samples.
  • In Keltner's description the centre line is a 10-day simple moving average of " typical price ", where typical price each day is the average of high, low and close,
  • What I have now is a simple moving average of the speed from the last 60 updates ( since it updates about twice a second, that would be about the average of the last 30 seconds ).
  • The lines above and below are drawn a distance from that centre line, a distance which is the simple moving average of the past 10 days'trading ranges ( i . e . range high to low on each day ).
  • The simple moving average corresponds to convolution with the constant B-spline ( a rectangular pulse ), and, for example, four iterations of a moving average yields a cubic B-spline as filter window which approximates the Gaussian quite well.
  • Notice that this technique has the same disadvantage as the simple moving average technique ( i . e ., it cannot be used until at least " k " observations have been made ), and that it entails a more complicated calculation at each step of the smoothing procedure.
