Hull MA (HMA): Indicator Documentation
====
Syntax====
DataSeries HullMA( DataSeries Series, int Period);
Parameter Description
| Series |
Data series used to produce the HMA calculation |
| Period |
Period to average the data series
|
Description
The Hull Moving Average (HMA) was created by trader, businessman, mathematician, and IT expert Alan Hull. It is a combination of weighted moving averages (WMA) designed to be more responsive to current price fluctuations while still smoothing prices.

This example illustrates how to construct and plot the HMA.
