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] 💬

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

Parameters ​

paramdescription
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 ​

csharp
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.

Utilities ​

Chaining ​

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

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

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

csharp
// 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:

csharp
AwesomeList awesomeList = new(fastPeriods, slowPeriods);

// call from your WebSocket or SSE message handler
void OnBarReceived(IBar bar) => awesomeList.Add(bar);

// based on `ICollection<AwesomeResult>`; fills as the handler runs
IReadOnlyList<AwesomeResult> results = awesomeList;

Subscribe to a BarHub for advanced streaming scenarios:

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

// call from your WebSocket or SSE message handler
void OnBarReceived(IBar bar) => barHub.Add(bar);

// results fill as the handler runs
IReadOnlyList<AwesomeResult> results = observer.Results;

See Buffer lists and Stream hubs for full usage guides.
