Bump org.ta4j:ta4j-core from 0.22.1 to 0.22.2

[dependabot]

Bumps org.ta4j:ta4j-core from 0.22.1 to 0.22.2.

Release notes

Sourced from org.ta4j:ta4j-core's releases.

0.22.2 (2026-02-15)

Breaking

• Trade model split: Trade is now an interface; the previous concrete implementation is SimulatedTrade (backtesting/simulation), and live executions are represented by LiveTrade.
• Swing indicator interfaces: Removed deprecated RecentSwingHighIndicator and RecentSwingLowIndicator; use RecentSwingIndicator and concrete implementations directly.

Added

• Charting time axis mode: Added TimeAxisMode with BAR_INDEX support to compress non-trading gaps (weekends/holidays) on charts while keeping bar timestamps intact.
• Concurrent real-time bar series pipeline: Introduced core support for concurrent, streaming bar ingestion with a dedicated series (ConcurrentBarSeries/builder), realtime bar model (RealtimeBar/BaseRealtimeBar), and streaming-bar ingestion helpers to enable candle reconciliation and side/liquidity-aware trade aggregation.
• Live trading domain model: Added ExecutionIntent, ExecutionFill, LiveTrade, and LiveTradingRecord with partial-fill tracking, multi-lot bookkeeping, and configurable matching (FIFO, LIFO, AVG_COST, SPECIFIC_ID).
• Strategy trade direction: Added Strategy#getStartingType() (default BUY) so strategies can declare long-first or short-first behavior explicitly.
• Open position analytics: Added PositionLedger, OpenPositionCostBasisCriterion, OpenPositionUnrealizedProfitCriterion, and TotalFeesCriterion for live exposure and fee analysis.
• Sharpe Ratio: Added SharpeRatioCriterion and its related calculation classes
• Equity-curve controls: Added OpenPositionHandling and PerformanceIndicator to standardize mark-to-market vs realized behavior across performance metrics.
• Added ThreeInsideUpIndicator and ThreeInsideDownIndicator
• Added MorningStarIndicator and EveningStarIndicator
• Added BullishKickerIndicator and BearishKickerIndicator
• Added PiercingIndicator and DarkCloudIndicator
• Threshold-based boolean rules: #1422 Added AndWithThresholdRule/OrWithThresholdRule that also work backwards with a certain threshold.
• Added versions-maven-plugin
• Elliott Wave analysis toolkit: Added ElliottWaveAnalyzer, ElliottAnalysisResult, configurable PatternSet, and the org.ta4j.core.indicators.elliott.swing detector/filter package for pluggable, chart-independent analysis.
• Elliott Wave confidence modeling: Added profile-driven confidence scoring with factor breakdowns, time alternation diagnostics, and granular Fibonacci relationship scoring.
• Elliott Wave trend bias: Added ElliottTrendBias and ElliottTrendBiasIndicator for scenario-weighted bullish/bearish context, plus ElliottScenarioSet#trendBias() and ElliottWaveFacade#trendBias() helpers.
• Elliott Wave strategy demos: Added ElliottWaveAdaptiveSwingAnalysis, ElliottWavePatternProfileDemo, ElliottWaveTrendBacktest, and HighRewardElliottWaveBacktest with HighRewardElliottWaveStrategy for selective impulse entries using confidence, alternation, and risk/reward filters.
• DonchianChannelFacade: #1407: Added DonchianChannelFacade new class providing a facade for DonchianChannel Indicators by using lightweight NumericIndicators
• Added constructors accepting custom ATR indicator to AverageTrueRangeStopGainRule AverageTrueRangeStopLossRule and AverageTrueRangeTrailingStopLossRule
• Sortino Ratio: Added SortinoRatioCriterion for downside deviation-based risk adjustment

Changed

• Bar builders null handling: Bar builders now skip null-valued bars entirely instead of inserting placeholder/null bars, leaving gaps when inputs are missing or invalid.
• Charting overlays: Refactored overlay renderer construction and centralized time-axis domain value selection to reduce branching without changing chart output.
• Charting defaults: Centralized chart styling defaults (anti-aliasing, background, title paint) for consistency across chart types.
• Chart builder metadata: Chart definitions now surface a shared metadata object for domain series, title, and time axis mode; chart plans expose a ChartContext and derive their primary series from it, with ChartWorkflow rendering helpers accepting contexts.
• TimeBarBuilder: Enhanced with trade ingestion logic, time alignment validation, and RealtimeBar support.
• BaseBarSeriesBuilder: Deprecated setConstrained in favor of deriving constrained mode from max-bar-count configuration.
• Release automation (two-phase, tokens, tooling): Two-phase workflows (prepare-release.yml, publish-release.yml) with optional direct push (RELEASE_DIRECT_PUSH). Token handling: preflight runs before checkout; GH_TA4J_REPO_TOKEN is used for checkout and push only when valid, otherwise github.token; fail fast when the token lacks write (warn in dry-run). Release process docs overhauled; pre-push hook runs actionlint on workflow changes (see CONTRIBUTING); agent workflow skips full build for workflow/CHANGELOG/docs-only changes.
• Release scheduler and discussions: Gated by RELEASE_SCHEDULER_ENABLED. Dispatches through prepare-release only when binary-impacting changes exist (pom.xml or src/main/**); AI prompt uses summarized binary changes and trimmed changelog with optional RELEASE_AI_MODEL. Scheduler and release runs post to GitHub Discussions with run mode and timestamp; binary path list and Maven Central summary in collapsible details; previous dry-run comments for the same tag are removed before posting.
• Publish-release manual trigger: For workflow_dispatch, releaseCommit is optional and auto-detected from release/<version>.md on the default branch so manual publishes require only the release version.
