- Introduced Massi validation tests to ensure mathematical properties hold for the Mass Index indicator. - Added Va validation tests for Volume Accumulation, checking for finite outputs and correct accumulation behavior. - Implemented Vf validation tests for Volume Force, verifying outputs for rising and falling prices, and ensuring batch and streaming results match. - Created Vo validation tests for Volume Oscillator, confirming behavior with constant, increasing, and decreasing volumes. - Developed Vroc validation tests for Volume Rate of Change, validating outputs for constant volume and changes in volume. - Updated project file to include new momentum indicators (MACD and RSI) in the compilation.
