Stocks & Commodities V. 23:4 (32-35): Weight + Volume + Move-Adjusted Moving Average: Itís WEVOMO! by Stephan Bisse
Moving averages: I use íem, you use íem, we all use íem, but can they really tell you anything about the future direction of a time series? In this article, the third of a series, we look at minimizing the lag even more using the weighted move- and volume-adjusted moving average.
Moving averages merely give you a view of where a time
series has been in the past. So how can it be used as a predictor? The only way is by adding more information Copyright into the calculation. But if you do this you have to make sure it is a leading indicator
for the time series in question. In other words, changes in the additional information must be correlated to future changes in the time series.
In my February 2005 article, ďVisiting MOMA,Ē I adjusted a simple moving average (SMA) by taking each datapoint in the lookback period and weighting it according to the absolute magnitude of the move that
preceded it relative to the sum of all of the absolutes in the lookback period. I christened this new moving average MOMA. In my March 2005 article, ďAdding Volume To The Move-Adjusted Moving Average,Ē I further adjusted MOMA by the relative magnitude of the volume of each datapoint in the lookback period to create a double-adjusted moving average, which I
christened VOMOMA. The idea behind MOMA is that a strong move in a given direction is a harbinger of the future direction of the market, and therefore weighting
an average by the magnitude of the moves between datapoints can produce timelier signals than a standard SMA. The additional step to VOMOMA is based on the logic that large moves accompanied by heavy volume are more significant than those panied by light volume. Therefore, a moving average adjusted by both volume and size of move can capture these additional nuances.
