Adaptive Kalman Trend Filter Indicator for MetaTrader 5
The Adaptive Kalman Trend Filter smooths price fluctuations to highlight the underlying market trend, adapting its responsiveness as market conditions change
Fisher Transform Indicator for MetaTrader 5
A Fisher Transform oscillator built from statistical first principles — normalizing price into a bounded range, then applying a logarithmic transform to produce sharp, well-defined reversal signals instead of the gradual turns typical of conventional oscillators. Internal recursive state is handled
SuperTrend Indicator for MetaTrader 5
A custom SuperTrend indicator built from first principles, combining an ATR-based volatility band with a ratchet mechanism to produce a clean, non-repainting trend line. Internal recursive state is managed through properly registered calculation buffers, avoiding the state-loss bugs common in

Real-Time Polynomial Regression: A Causal Savitzky-Golay Implementation for MQL5 for MetaTrader 5
We adapt the Savitzky–Golay filter to a strictly causal, real-time form for MQL5 and derive the fixed coefficients for end-point evaluation. The article provides a full indicator and an Expert Advisor, explains the edge-evaluation noise sensitivity, and implements a multi-bar confirmation safeguard
The Kalman Filter for Price Smoothing: An Exact Implementation in MQL5 for MetaTrader 5
This article implements the scalar Kalman Filter for price smoothing in MQL5 using the standard local-level model and the exact prediction–update equations. It explains how process and measurement noise (Q, R) shape the Kalman gain, builds two independently configured filters into a fast/slow
Making Custom Indicators for Beginners (Part 2): Fisher-style Indicator for MetaTrader 5
This article develops a Fisher‑style Indicator in MQL5 from first principles: normalize price within a recent high/low window, smooth and clamp the value, then apply a logarithmic transform. We cover buffer wiring, calculation‑buffer state management across bars, and seeding for stable starts. An
Making Custom Indicators for Beginners (Part 1): SuperTrend Indicator for MetaTrader 5
This article builds a robust SuperTrend indicator in MQL5 using ATR-based bands, a ratchet mechanism, and strict series indexing to avoid silent recursion errors and repainting on closed bars. We walk through buffer binding, ATR handle management, seeding, and arrow confirmation logic. A companion
