For a SMA movingaverage calculated using M days, the lag is roughly M 2 days. Thus, if we are using a 100 days SMA, this means we may be late by almost 50 days, which can significantly affect our strategy. One way to reduce the lag induced by the use of the SMA is to use the so-called Exponential MovingAverage (EMA), defined as..

The sum of the periods is 1+2+3 = 6. So we have (180 + 90 + 50) / 6 = 53.33 as a three-period weighted average. The WMA value of 53.33 compares to the SMA calculation of 51.67. The division by 6 in this step is what brought the weightings sum to 6 / 6 = 1. Let’s look at another example with a proper look at the weighted factor.

Volume-weighted average price ( VWAP) is a lagging volume indicator. The VWAP is a weighted moving average that uses the volume as the weighting factor so that higher volume days have more weight. It is a non-cumulative moving average, so only data within the time period is used in the calculation. Although this function is available in talib.
