    Commander in Pips: Well, in fact, this is not crucial for you to know the formula, because software will do this automatically. But still, I suppose this will be useful, try to calculate it, at least once. Ok, I do it by myself. Let’s calculate the same 7-period MA, but using exponential way of averaging:

    Period NTotal number of periods (n)SF=2/(n+1)Close price P(t)EMA(t-1)EMA(t)
    170.251.41851.40371.4074
    270.251.42071.39801.4037
    370.251.41371.39271.3980
    470.251.39881.39071.3927
    570.251.38821.39161.3907
    670.251.39781.38951.3916
    770.251.39731.38691.3895
    Here we use the same close prices and candles as in previous part, when we’ve calculated SMA. Take a note, that EMA(t-1) value for the 7th period (most distant in time) is a close price of 8th bar, that stands before our seven consecutive close prices, that directly used in calculation. Now look at the chart:

    Our estimation of 7-period EMA is different from software’s calculation for 2 pips due rounding. But don’t be afraid – you will not have to do this manually. Let’s better to see, how the qualities of EMA manifest compares to SMA. In the circle we see that the EMA is above the SMA. This is because during the recent 4 periods, the market shows nice thrust move up. And, as we know, the EMA puts more weight onto the most recent periods. That’s why it shows most recent sentiment more clear.



    If you take a look at previous retracement, when 4 consecutive black candles have appeared – we can see the same – EMA moved below SMA and has shown sharper reaction to sentiment changing.

    From this perspective it appears, that an EMA better shows what traders are doing now, than SMA.

    Modified Moving Average (MAV)


    We will not speak much about this type of MA, because it does not have some exceptional qualities. But it does exist and we just specify formula for its calculation:

    MAV(t)=MAV(t-1)+(P(t) -MAV(t-1))/n

    Maybe, sometime you will need it.
