# Chaikin Oscillator

Created by Marc Chaikin, the Chaikin Oscillator is the difference between fast and slow Exponential Moving Averages (EMA) of the Accumulation/Distribution Line (ADL). [Discuss] ðŸ’¬

```
// C# usage syntax
IEnumerable<ChaikinOscResult> results =
quotes.GetChaikinOsc(fastPeriods, slowPeriods);
```

## Parameters

`fastPeriods`

* int* - Number of periods (

`F`

) in the ADL fast EMA. Must be greater than 0 and smaller than `S`

. Default is 3.`slowPeriods`

* int* - Number of periods (

`S`

) in the ADL slow EMA. Must be greater `F`

. Default is 10.### Historical quotes requirements

You must have at least `2Ã—S`

or `S+100`

periods of `quotes`

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

- 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`

periods will have`null`

values for`Oscillator`

since thereâ€™s not enough data to calculate.

Convergence warning: The first`S+100`

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

### ChaikinOscResult

`Date`

* DateTime* - Date from evaluated

`TQuote`

`MoneyFlowMultiplier`

* double* - Money Flow Multiplier

`MoneyFlowVolume`

* double* - Money Flow Volume

`Adl`

* double* - Accumulation Distribution Line (ADL)

`Oscillator`

* double* - Chaikin Oscillator

Warning: absolute values in MFV, ADL, and Oscillator are somewhat meaningless. Use with caution.

### Utilities

See Utilities and helpers for more information.

## Chaining

Results can be further processed on `Oscillator`

with additional chain-enabled indicators.

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

This indicator must be generated from `quotes`

and **cannot** be generated from results of another chain-enabled indicator or method.
