How to Calculate MME?

[Marcio Andrade]

How do I calculate an MME via code? I used several formulas and I can not get it right. The most correct was:

lastMME = (v1 + v2 + v3 + v4 + v5 + v6 + v7 + v8 + v9)/9;
MME = (PriceActual-lastMME)*(2/(9+1))+lastMME;

MME is the Portuguese abbreviation (Média Móvel Exponencial). In English it is called EMA (Exponential Moving Average).

Here are some links to help you understand how it is calculated:

• Incremental calculation of weighted mean and variance (Tony Finch) - http://people.ds.cam.ac.uk/fanf2/hermes/doc/antiforgery/stats.pdf

The PDF file (Incremental calculation of weighted mean and variance) is for me the most informative because it also shows how to calculate the variance and standard deviation in an incremental way with much less rounding errors which is perfect for indicators.

Dear, Thanks!!!!!! PERFECT.
