I've found this sophisticated implementation of the differential Gaussian filtering, with an oscillating (+/-/+) pattern charateristic of Laplacian of Gaussians (LoG), Difference of Gaussians (DoG) and Mexican Hat Wavelets (MHW), also known as Ricker Wavelets.
The indicator calculates two primary buffers:
Buffer1: Based on (HLC4 + Close) / 2
Buffer2: Based on (HLC4 + Open) / 2
The trend is determined by the relationship between these buffers, not by price position relative to the indicator.
It's very different from traditional MAs and also from digital filters, like Ehlers' ones or Kalman, and it performs at best on higher TFs (H1+) in identifying turning points and reversals. It's worth more testing.

-Multi-Instance Robustness: Reworked the core logic to ensure multiple instances of the indicator can run on the same chart with different settings (e.g., MTF and colors) without interfering with each other.
-Code Modernization: Replaced the legacy MQL4 drawing with a single, efficient DRAW_COLOR_LINE for a cleaner two-color display and improved performance.
-New Feature - ATR Noise Filter: Added an adaptive ATR-based filter to significantly reduce whipsaws in ranging markets and improve signal quality.
-New Feature - Full Customization & Alerts: Implemented comprehensive user settings including unique color presets, visual options, and a complete suite of trend-change alerts.
-Performance Overhaul & Bug Fixes: Optimized MTF calculations using ArrayBsearch for maximum speed and fixed critical bugs related to interpolation and data indexing to ensure accuracy and stability: 90% less CPU usage.
MT5 version is not repainting in MTF mode.
