# Hull Moving Average (HMA)

Created by Alan Hull, the Hull Moving Average is a modified weighted average of price that reduces lag. [Discuss]

```
// usage
IEnumerable<HmaResult> results =
quotes.GetHma(lookbackPeriods);
```

## Parameters

`lookbackPeriods`

* int* - Number of periods (

`N`

) in the moving average. Must be greater than 1.### Historical quotes requirements

You must have at least `N+(integer of SQRT(N))-1`

periods of `quotes`

to cover the warmup periods.

`quotes`

is a collection of generic `TQuote`

historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

## Response

```
IEnumerable<HmaResult>
```

- This method returns a time series of all available indicator values for the
`quotes`

provided. - It always returns the same number of elements as there are in the historical quotes.
- It does not return a single incremental indicator value.
- The first
`N+(integer of SQRT(N))-1`

periods will have`null`

values since there’s not enough data to calculate.

### HmaResult

`Date`

* DateTime* - Date from evaluated

`TQuote`

`Hma`

* double* - Hull moving average

### Utilities

See Utilities and helpers for more information.

## Chaining

This indicator may be generated from any chain-enabled indicator or method.

```
// example
var results = quotes
.Use(CandlePart.HL2)
.GetHma(..);
```

Results can be further processed on `Hma`

with additional chain-enabled indicators.

```
// example
var results = quotes
.GetHma(..)
.GetRsi(..);
```
