# Simple Moving Average (SMA)

Simple Moving Average is the average price over a lookback window. An extended analysis option includes mean absolute deviation (MAD), mean square error (MSE), and mean absolute percentage error (MAPE). [Discuss] ðŸ’¬

```
// C# usage syntax (with Close price)
IEnumerable<SmaResult> results =
quotes.GetSma(lookbackPeriods);
```

## Parameters

`lookbackPeriods`

* int* - Number of periods (

`N`

) in the lookback window. Must be greater than 0.### 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<SmaResult>
```

- 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.

### SmaResult

`Date`

* DateTime* - Date from evaluated

`TQuote`

`Sma`

* double* - Simple moving average

### Utilities

See Utilities and helpers for more information.

## Analysis

This indicator has an extended version with more analysis.

```
// C# usage syntax
IEnumberable<SmaAnalysis> analysis =
results.GetSmaAnalysis();
```

### SmaAnalysis

`Date`

* DateTime* - Date from evaluated

`TQuote`

`Sma`

* decimal* - Simple moving average

`Mad`

* double* - Mean absolute deviation

`Mse`

* double* - Mean square error

`Mape`

* double* - Mean absolute percentage error

## Chaining

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

```
// example
var results = quotes
.Use(CandlePart.Volume)
.GetSma(..);
```

Results can be further processed on `Sma`

with additional chain-enabled indicators.

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