What's Changed

Breaking

  • Updated project Java JDK from 11 > 21
  • Updated Github workflows to use JDK 21
  • Extracted NumFactory as source of numbers with defined precision
  • Replaced ZonedDateTime with Instant
  • Renamed FixedDecimalIndicator with FixedNumIndicator
  • Moved BaseBarBuilder and BaseBarBuilderFactory to bars-package and renamed to TimeBarBuilder and TimeBarBuilderFactory
  • Renamed BaseBarConvertibleBuilderTest to BaseBarSeriesBuilderTest
  • Renamed Indicator.getUnstableBars to Indicator.getCountOfUnstableBars
  • Moved indicators/AbstractEMAIndicator to indicators/averages-package
  • Moved indicators/DoubleEMAIndicator to indicators/averages-package
  • Moved indicators/EMAIndicator to indicators/averages-package
  • Moved indicators/HMAIndicator to indicators/averages-package
  • Moved indicators/KAMAIndicator to indicators/averages-package
  • Moved indicators/LWMAIndicator to indicators/averages-package
  • Moved indicators/MMAIndicator to indicators/averages-package
  • Moved indicators/SMAIndicator to indicators/averages-package
  • Moved indicators/TripleEMAIndicator to indicators/averages-package
  • Moved indicators/WMAIndicator to indicators/averages-package
  • Moved indicators/ZLEMAIndicator to indicators/averages-package
  • Implemented sharing of MathContext in DecimalNum. For creating numbers, NumFactory implementations are the preferred way.

Fixed

  • Fixed BaseBar.toString() to avoid NullPointerException if any of its property is null
  • Fixed SMAIndicatorTest to set the endTime of the next bar correctly
  • Fixed SMAIndicatorMovingSeriesTest to set the endTime of the next bar correctly
  • Use UTC TimeZone for AroonOscillatorIndicatorTest, PivotPointIndicatorTest
  • Fixed MockBarBuilder to use Instant.now for beginTime
  • Fixed RecentSwingHighIndicatorTest to create bars consistently
  • Fixed LSMAIndicator to fix lsma calculation for incorrect values

Changed

  • Updated jfreechart dependency in ta4j-examples project from 1.5.3 to 1.5.5 to resolve CVE-2023-52070
  • Updated logback-classic 1.4.12 > 1.5.6 to resolve CVE-2023-6481
  • Cleaned code by using new java syntax text blocks
  • Faster test execution by using String.lines() instead of String concatenation
  • Improve Javadoc for DecimalNumand DoubleNum
  • Allowed JUnit5 for new tests. Old remain as is.

Added

  • added HeikinAshiBarAggregator: Heikin-Ashi bar aggregator implementation
  • added HeikinAshiBarBuilder: Heikin-Ashi bar builder implementation

  • Added VolumeBarBuilder to bars-package to aggregate bars after a fixed number of contracts (volume)
  • Added TickBarBuilder to bars-package
  • Added VolumeBarBuilder to bars-package
  • Added Indicator.isStable: is true if the indicator no longer produces incorrect values due to insufficient data
