Seeing that many indicators use a MA for calculation. It may be possible to use new MA algorithm to improve on their calculation.
For example, the RS in RSI is something like RS = EMA(up days) / EMA(down days). We could change it to RS = HMA(up days) / HMA(down days). Since HMA is much faster, the resulting H-RSI may be faster too. This can be useful in day trading strategies.
More work needs to be done to test this idea.
