The image uses NinjaTrader simulated data. The HMA is 45 period, the VMA is a 12 period with a volatility period of 9. After playing around for a little while they seem to be equivalent. Each triggering at the same points of the graph with few if any false positives. Not much difference I can see in responsiveness. I would think that the VMA might have more use as an indicator that is based on moving average angle. (Just guessing here.) When an up move is done it flattens out quickly instead of slowly.
