I don't have a specific use for it per say, but I'm interested in finding a MA that has very low lag (sticks to the price) while retaining a high smoothing factor... This might not be perfect but I thought it was interesting (maybe not).
I think you could use this MA the same way you use other MAs (determining trend if MA0 > MA1 then trend is up or if price closes above MA then on buys, etc)
