Range-weighted RMA (Relative Moving Average) filtered
This is a range weighted relative moving average filtered.
It uses Mladen's range-weighted method which uses the high-low of the candlestick it is calculated for as it's weight.
The emphasis is in it's calculation of the higher volatility candlesticks and response to price changes of those candlesticks are accelerated.
At the end of the day, the range-weighted average is similar to simple moving average. The difference can only be seen at times of high ranges where it becomes "faster" than the SMA.
PS: A "Double Smoothed" version is available here: Relative Moving Average Double Smoothed for MT4 & if you are new to price filtering and would like to learn more about it, please see: What is price filtering in MT4?
