- 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.
