- MCNMA (McNicholl EMA): Implements a zero-lag TEMA using a cascaded EMA structure for enhanced responsiveness.
- NLMA (Non-Lag Moving Average): Utilizes a damped cosine kernel to achieve reduced lag in moving averages.
- NMA (Natural Moving Average): Adapts smoothing based on volatility profiles using a square-root kernel.
- NYQMA (Nyquist Moving Average): Applies the Nyquist-Shannon theorem to prevent aliasing in cascaded moving averages.
- RAIN (Rainbow Moving Average): Combines multiple SMA layers with weighted averages for multi-scale smoothing.
- TRAMA (Trend Regularity Adaptive Moving Average): Adapts smoothing based on the frequency of new highs and lows in price data.
- Implemented SgmaIndicator class in C# with properties for Period, Degree, and Source.
- Added unit tests for SgmaIndicator covering constructor defaults, initialization, and various update scenarios.
- Created a new Quantower adapter for the SGMA indicator, including input parameters and line series setup.
- Removed legacy SGMA implementation and tests to streamline the codebase.
- Updated project files to include new indicator and tests in the build process.
- Generated a missing indicators report and outlined a plan for oscillator documentation rewrite.
- Implemented Prime method in Vel, Ao, Apo, Frama, Adl, Adosc, Aobv, Cmf, Efi, Eom, Iii, Kvo, Mfi, Nvi, Obv, Pvd, Pvi, Pvo, Pvr, Pvt, Tvi, Twap, Va, Vf, Vo, Vroc, Vwad, Vwap, and Vwma classes.
- The Prime method resets the indicator state and processes the provided historical bar data to initialize the indicator.
