# Moving Average Convergence / Divergence (MACD)

Created by Gerald Appel, MACD is a simple oscillator view of two converging / diverging exponential moving averages and their differences. [Discuss]

```
// usage (with Close price)
IEnumerable<MacdResult> results =
quotes.GetMacd(fastPeriods, slowPeriods, signalPeriods);
```

## Parameters

`fastPeriods`

* int* - Number of periods (

`F`

) for the faster moving average. Must be greater than 0. Default is 12.`slowPeriods`

* int* - Number of periods (

`S`

) for the slower moving average. Must be greater than `fastPeriods`

. Default is 26.`signalPeriods`

* int* - Number of periods (

`P`

) for the moving average of MACD. Must be greater than or equal to 0. Default is 9.### Historical quotes requirements

You must have at least `2×(S+P)`

or `S+P+100`

worth of `quotes`

, whichever is more, to cover the convergence periods. Since this uses a smoothing technique, we recommend you use at least `S+P+250`

data points prior to the intended usage date for better precision.

`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<MacdResult>
```

- 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
`S-1`

slow periods will have`null`

values since there’s not enough data to calculate.

Convergence warning: The first`S+P+250`

periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

### MacdResult

`Date`

* DateTime* - Date from evaluated

`TQuote`

`Macd`

* double* - The MACD line is the difference between slow and fast moving averages (

`MACD = FastEma - SlowEma`

)`Signal`

* double* - Moving average of the

`MACD`

line`Histogram`

* double* - Gap between of the

`MACD`

and `Signal`

line`FastEma`

* double* - Fast Exponential Moving Average

`SlowEma`

* double* - Slow Exponential Moving Average

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)
.GetMacd(..);
```

Results can be further processed on `Macd`

with additional chain-enabled indicators.

```
// example
var results = quotes
.GetMacd(..)
.GetSlope(..);
```
