3.0.0

What's Changed

Version 3 enables streaming and incremental stock indicator use cases by add two new styles:

• Buffer-style lists for simple incrementing use cases
• Advanced stream hubs for complex event based architectures

Our standard series (batch) style indicators from v2 remain in their original form and will continue to be the first choice for most users.

We've also renamed the NuGet package from Skender.Stock.Indicators to FacioQuo.Stock.Indicators along with our transfer of the repo out of a personal account to facioquo.

See our updated documentation site (dotnet.stockindicators.dev) for additional details and migration guide.

3.0.0-preview.2

We’ve released a new preview release for v3 of the Stock Indicators for .NET NuGet package, containing widely implemented streaming style indicators.
See Skender.Stock.Indicators @ NuGet.org for more information.

Warning

Preview releases are experimental and volatile with breaking changes and conventions.

Note

There will be a series of preview releases that implement streaming use cases. We expect possibly 1-2 additional preview pre-releases before we make an official stable v3 package.

• see #1014 for overall v3 progress

What's Changed

• wide implementation of buffer list incrementing indicators, and streaming hubs

Incrementally add data with buffer lists

For scenarios where quotes arrive one at a time, buffer lists provide efficient incremental processing without recalculating the entire history.

// create list
SmaList<SmaResult> smaList = new(lookbackPeriods: 20);

// add new quotes incrementally
smaList.Add(newQuote);

Buffer lists maintain internal state and automatically manage the warmup period, making them ideal for basic live data feeds and incremental updates.

Streaming hubs with observer patterns

Hubs provides a reactive, subscription-based pattern for streaming market data with automatic cascading calculations for advances scenarios.

// create provider with chain of indicators
QuoteHub provider = new QuoteHub();
SmaHub smaHub = provider.ToSmaHub(20);
RsiHub rsiHub = smaHub.ToRsiHub(14);  // RSI of SMA

// publish quotes - observers auto-update in cascade
provider.Add(newQuote);

// consume downstream hubs indicators
IReadOnlyList<RsiResult> = rsiHub.Results;

The observer cascade ensures that when a new quote arrives, all chained indicators update automatically in the correct sequence.

2.6.1

Release 2.6.1

📦 Package deployed to nuget.org

Package Details

• Name: Skender.Stock.Indicators
• Version: 2.6.1

What's Changed

• revert: Restore .NET Standard 2.0 by @DaveSkender in #1312

Note

We're restoring .NET Standard 2.0 for legacy .NET Framework 4.8 compatibility. We'll maintain this support for v2, but will very likely drop .NET Standard in the next major version (v3) since it limits our ability to use newer .NET capabilities.

3.0.0-preview.1

We’ve released a new partial preview release for v3 of the Stock Indicators for .NET NuGet package.

Warning

Preview releases are experimental and volatile with breaking changes and conventions.

Note

There will be a series of preview releases that implement streaming use cases. We expect possibly 2-3 additional preview pre-releases before we make an official stable v3 package.
