Learnable Curves, Not Weights: A Kolmogorov-Arnold Network from Scratch

This article builds a Kolmogorov–Arnold Network (KAN) in MQL5, where every edge carries a learnable B‑spline curve rather than a scalar weight. We construct the spline basis, assemble edges and a layer, and fit all coefficients by ridge‑regularized least‑squares in a single solve. The model is delivered as an indicator that visualizes the learned curves and an Expert Advisor that acts on the prediction, providing an interpretable, reusable codebase.

Bloch's Relative Moving Average (RMA) Framework Implementation In MQL5

We port Daniel Bloch's Relative Moving Average framework into a complete MetaTrader 5 system. Instead of smoothing price, the RMA measures where price sits inside its own recent distribution on a [0,1] fractile scale, and drives four cross-strategies with a regime-adaptive exit. Includes the engine, indicators, and a backtested Expert Advisor.

Trends and Traditions: Using Rademacher Functions in Trading

Although the functions we will discuss have been known for quite some time, their application in the field of trading remains terra incognita to this day. In this article, we will explore some of the opportunities these old-but-new functions offer for developing trading strategies and assess their potential.

Published article "Neural Networks in Trading: Adaptive Periodic Segmentation (LightGTS)".

Neural Networks in Trading: Adaptive Periodic Segmentation (LightGTS)

We invite you to learn about the innovative technique of adaptive patching — a method for flexibly segmenting time series while taking their internal periodicity into account. We will also look at an efficient encoding technique that preserves important semantic characteristics when working with data at different scales. These methods open up new possibilities for the accurate processing of complex, multiscale data characteristic of financial markets and significantly improve the stability and reliability of forecasts.

Published article "A Trailing Stop Engine in MQL5 Supporting Five Trail Methods Simultaneously".

A Trailing Stop Engine in MQL5 Supporting Five Trail Methods Simultaneously

We implement CTrailingEngine, an interface-driven MQL5 engine that evaluates each registered position on every tick and applies one of five trailing methods: fixed-pip, ATR multiplier, Parabolic SAR, percentage-of-profit, or swing high/low. All methods share the ITrailMethod contract, so new trails plug in without engine edits. Strict improvement and a one-point guard block backward moves and no-change SLTP modifications.

Published article "Building Volatility Models in MQL5 (Part V): Implementing EGARCH as an Alternate Asymmetric Volatility Process".

Building Volatility Models in MQL5 (Part V): Implementing EGARCH as an Alternate Asymmetric Volatility Process

EGARCH models log-variance, avoiding the non-negativity constraints that can distort GARCH estimates and enabling a clear treatment of leverage asymmetry. The article provides a complete MQL5 implementation with logarithmic backcasting, simulation-based multi-step forecasting, and diagnostics including the Engle–Ng Sign Bias, Leverage Correlation, and Volatility Runs tests. Practical outputs include EGARCH Volatility, an Innovation Z-Score, and an Asymmetric Volatility Regime Oscillator to support regime analysis and strategy design.

Published article "Elite Crystal Evolution Algorithm (CEO-inspired): Practical Implementation".

Elite Crystal Evolution Algorithm (CEO-inspired): Practical Implementation

Experimental evaluation on standard benchmark functions reveals the advantages and limitations of directly adapting combinatorial algorithms. The article provides a detailed description of the ECEA algorithm's mechanisms and test results.

Published article "Feature Engineering for ML (Part 12): Fractal Features in MQL5".

Feature Engineering for ML (Part 12): Fractal Features in MQL5

A direct MQL5 port of the fractal detector writes each pattern at its center bar, so a buffer read by an expert advisor holds a value that only existed n bars later. We implement CFractalFeatures.mqh with ProcessBar for bar-by-bar use and Compute for full-series recalculation, covering detection, strength scored against a fixed or volatility-scaled floor, an event-based support/resistance ring, and trend-filtered breakout signals. Output is eighteen buffers published at the confirmation bar, verified against the Python reference to within 1e-13.

  • iS7N_TREND.mq5 Now it's two-color (or two-mode) trend indicator, the number of calculated bars can be specified.
  • LotSize Calculation This is a simple script file to compute lot size either using risk percentage approach or the actual amount to risk.
  • Functions to simplify work with orders All we want is to think about algorithms and methods, not about syntax and values how to place orders. Here you have simple functions to manage positions in MQL5.

  • Broker Spec Inspector Prints the invisible contract limits that silently reject orders: stops level, freeze level, min/step/max lot, tick size and value, spread type, execution mode, swaps, and the margin needed for the minimum lot against your free margin.
  • Custom Simple Moving Average A two-stage adaptive moving average (base average + secondary smoothing) that colors itself by slope and marks price/average crossovers with arrows.
  • Reverse RSI Bands Reverse RSI Bands is a leading indicator that mathematically reverse-engineers the RSI formula. It plots precise target price bands directly on the main chart, showing exactly at what price the RSI will hit your specified overbought or oversold levels in real-time.
  • Session Opening Range Breakout EA An Expert Advisor that measures the high/low of a defined session opening window, then trades the confirmed breakout of that range with risk-based position sizing and a one-trade-per-session cap.

Price Action Analysis Toolkit Development (Part 78): Extending the Indicator Search Panel with Symbol Selection in MQL5

We continue enhancing our modular indicator search panel by adding symbol selection capabilities. The implementation allows users to search for built-in indicators, choose a destination symbol, and attach the selected indicator without opening multiple charts or running separate Expert Advisor instances.

Measuring What Matters (Part 3): The Reconstruction Engine — Validating Risk Footprints with Matrix Algebra

This article performs a numerical verification of MQL5 eigendecomposition for a covariance matrix using the spectral theorem A = V Λ Vᵀ. It reconstructs the matrix with Diag(), Transpose(), and MatMul(), computes the residual and its Frobenius norm, and shows that deviations remain at floating‑point precision, with results printed to the Experts journal.

Detecting Structural Breakpoints in Price Series Using CUSUM in MQL5 (Part 2): Implementing the Detector as a Native MQL5 Indicator

This article benchmarks CUSUM_Breakpoint.mq5 against the Siegmund ARL₀ prediction on live‑like data. The empirical false‑alarm rate is about five times higher than theory for all tested symbols and timeframes, and confirmations show sensitivity to variance changes over mean changes. Practitioners should calibrate h and k on the target instrument's history and apply the signal to manage volatility regimes, not to infer directional shifts.

Neural Networks in Trading: An Intelligent Forecast Pipeline (Conclusion)

The article provides a fascinating look at how SwiGLU embedding reveals hidden market patterns, and how a sparse Mixture of Experts within a Decoder-Only Transformer makes forecasts more accurate at reasonable computational cost. We take an in-depth look at the integration of Time‑MoE into MQL5 and OpenCL, and provide a step-by-step guide to configuring and training the model.

How to Detect and Normalize Chart Objects in MQL5 (Part 5): Fibonacci in Focus

The article bridges automated placement with manual analysis for the Fibonacci family in MQL5. It scans charts, identifies user Fibonacci objects, and normalizes their level arrays, interaction flags, and visuals per object type while preserving coordinates. With manual-priority enforcement, Expert Advisors can evaluate both human and code-generated tools reliably, without duplicates or runtime indexing issues.

Machine Learning Without the Black Box: The Tsetlin Machine for Trading

This article builds a white-box classifier in MQL5 using the Tsetlin Machine. It learns human-readable AND-rules instead of weights, trains with integer state updates, and requires no external dependencies. You will assemble the automaton, clause, and multi-class voter, verify on XOR and other boolean tasks, booleanize indicators, label by forward ATR-scaled return, save the model to CSV, and view active rules on a live chart.
