Building a Hull Moving Average Momentum Oscillator in MQL5

Building a Hull Moving Average Momentum Oscillator in MQL5

This article builds a Hull Moving Average Momentum indicator in MQL5 by combining raw price momentum with Hull MA smoothing. We compute momentum as the close-to-close difference over a user-defined length, form 2×Fast WMA − Slow WMA, then apply a final WMA with a square‑root period. The implementation covers inputs, buffers, warm-up/recalculation, and visualization with a color-coded line and zero-line filling, helping interpret positive/negative momentum without treating zero crossings as signals.

Price Action Analysis Toolkit Development (Part 79): Extending the Indicator Search Panel with Dynamic Input Parameter Configuration

Price Action Analysis Toolkit Development (Part 79): Extending the Indicator Search Panel with Dynamic Input Parameter Configuration

We integrate parameter configuration into the indicator search workflow in MQL5. A central repository describes each indicator's inputs, a dynamic dialog renders controls from those definitions, and the dialog validates entries and converts them to MqlParam. The chart launcher then creates the indicator with IndicatorCreate using the provided values. This streamlines attaching indicators with custom settings on the chosen symbol.

From Novice to Expert: Candlestick Momentum Confirmation for Classic Crossover Strategies

From Novice to Expert: Candlestick Momentum Confirmation for Classic Crossover Strategies

In this article, we refine a moving average crossover strategy with a momentum candle filter and an immediate retracement bar confirmation. When both conditions are met, a pending stop order is placed using a pivot-based stop loss and a 2R take profit. The complete MQL5 Expert Advisor code, finite-state-machine logic, and chart annotations are detailed.

Automating Chart Patterns in MQL5 (Part 1): The Multi-Timeframe Swing Structure Engine

Automating Chart Patterns in MQL5 (Part 1): The Multi-Timeframe Swing Structure Engine

This article presents CSwingEngine, a reusable MQL5 class that detects H4 swing highs and lows, labels them HH, LH, HL, or LL, and classifies market structure as trend or range. Swings are always computed on H4, regardless of the attached chart, and each point draws correctly on lower timeframes via native datetime anchoring. The engine exposes a clean interface to query the current trend and retrieve the swing array for context-aware pattern logic.

Feature Engineering for ML (Part 14): Trend-Scanning Features in MQL5

Feature Engineering for ML (Part 14): Trend-Scanning Features in MQL5

A naive MQL5 port of trend-scanning features recomputes each candidate window per bar at O(H·L) cost. This article introduces CTrendScanningFeatures.mqh, which maintains three running sums per horizon and updates them in O(1) per bar, verified against a Python reference. The indicator exposes four causal buffers - window, slope, t_value, rsquared - at the confirmation bar and corrects a sign inversion present in the original backward labeling mode.

Feature Engineering for ML (Part 13): Trend-Scanning Features in Python

Feature Engineering for ML (Part 13): Trend-Scanning Features in Python

Trend-scanning supports both forward and backward windows, and the labeling default is unsafe for features: it looks ahead and boosts next-bar agreement well above chance on random walks. We provide a dedicated wrapper, get trend scanning features, that forces computational causal and returns only window, slope, t value, and rsquared. A second analysis quantifies errors introduced by the default log transform on signed series.

Building a Crosshair Volume Profile Indicator in MQL5

Building a Crosshair Volume Profile Indicator in MQL5

We implement an interactive Crosshair Volume Profile indicator in MQL5 for MetaTrader 5. Using a right-click-and-drag crosshair, you select a chart region; the indicator then builds adaptive price bins, accumulates tick or real volume, detects the POC, and renders the profile on the chart. You will practice OnChartEvent()-driven interaction, cursor-to-time/price mapping, and price-source models (Close, Median, Typical, Weighted, OHLC4) for on-demand volume analysis.

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.
