Awesome Oscillator (AO)

Created by Bill Williams, the Awesome Oscillator (aka Super AO) is a measure of the gap between a fast and slow period modified moving average. [Discuss] 💬

// C# usage syntax
IReadOnlyList<AwesomeResult> results =
  bars.ToAwesome(fastPeriods, slowPeriods);

Parameters

param	type	description
fastPeriods	int	Number of periods (F) for the faster moving average. Must be greater than 0. Default is 5.
slowPeriods	int	Number of periods (S) for the slower moving average. Must be greater than fastPeriods. Default is 34.

Historical price bars requirements

You must have at least S periods of bars to cover the warmup periods.

bars is a collection of generic TBar historical price bars. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Response

IReadOnlyList<AwesomeResult>

• This method returns a time series of all available indicator values for the bars provided.
• It always returns the same number of elements as there are in the historical price bars.
• It does not return a single incremental indicator value.
• The first period S-1 periods will have null values since there's not enough data to calculate.

AwesomeResult

property	type	description
Timestamp	DateTime	Date from evaluated TBar
Oscillator	double	Awesome Oscillator
Normalized	double	100 × Oscillator ÷ (median price)

Utilities

• .Condense()
• .Find(lookupDate)
• .RemoveWarmupPeriods()
• .RemoveWarmupPeriods(removePeriods)

See Utilities and helpers for more information.

Chaining

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

// example
var results = bars
    .Use(CandlePart.HL2)
    .ToAwesome(..);

Results can be further processed on Oscillator with additional chain-enabled indicators.

// example
var results = bars
    .ToAwesome(..)
    .ToRsi(..);

See Chaining indicators for more.

Streaming

Use the buffer-style List<T> when you need incremental calculations without a hub:

AwesomeList awesomeList = new(fastPeriods, slowPeriods);

foreach (IBar bar in bars)  // simulating stream
{
  awesomeList.Add(bar);
}

// based on `ICollection<AwesomeResult>`
IReadOnlyList<AwesomeResult> results = awesomeList;

Subscribe to a BarHub for advanced streaming scenarios:

BarHub barHub = new();
AwesomeHub observer = barHub.ToAwesomeHub(fastPeriods, slowPeriods);

foreach (IBar bar in bars)  // simulating stream
{
  barHub.Add(bar);
}

IReadOnlyList<AwesomeResult> results = observer.Results;

See Buffer lists and Stream hubs for full usage guides.
