- Implemented Aroon Indicator with constructor, initialization, and update methods. - Added unit tests for AroonIndicator to verify default settings, historical depth, short name, source code link, and processing of historical bars. - Created Aroon class for core calculations, including methods for updating with TBar and TBarSeries. - Added validation tests to ensure Aroon calculations match results from Skender and TA-Lib. - Updated documentation for Aroon Indicator with calculation methods and usage examples. - Refactored Dema and Wma classes to use Batch methods for calculations. - Enhanced performance benchmarks by increasing bar count and integrating OoplesFinance indicators. - Updated project dependencies to include OoplesFinance.StockIndicators.
