# Arnaud Legoux Moving Average (ALMA)

Created by Arnaud Legoux and Dimitrios Kouzis-Loukas, ALMA is a normal Gaussian distribution weighted moving average of price. [Discuss] ðŸ’¬

```
// usage
IEnumerable<AlmaResult> results =
quotes.GetAlma(lookbackPeriods, offset, sigma);
```

## Parameters

`lookbackPeriods`

* int* - Number of periods (

`N`

) in the moving average. Must be greater than 1, but is typically in the 5-20 range. Default is 9.`offset`

* double* - Adjusts smoothness versus responsiveness on a scale from 0 to 1; where 1 is max responsiveness. Default is 0.85.

`sigma`

* double* - Defines the width of the Gaussian normal distribution. Must be greater than 0. Default is 6.

### Historical quotes requirements

You must have at least `N`

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<AlmaResult>
```

- 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-1`

periods will have`null`

values since thereâ€™s not enough data to calculate.

### AlmaResult

`Date`

* DateTime* - Date from evaluated

`TQuote`

`Alma`

* double* - Arnaud Legoux 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)
.GetAlma(..);
```

Results can be further processed on `Alma`

with additional chain-enabled indicators.

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