The Timeframe Visual Analyzer overlays candles from two selectable higher timeframes on the active chart, with timestamp alignment, separate bullish and bearish styling, and adjustable transparency. This lets traders compare current price action with broader…

This article extends a basic real-time ticker panel by adding asset images, richer quote labels, and click-to-open chart behavior. It describes encapsulating bitmap display in a class so image handling can later be changed independently, and expanding text…

The article describes a trading adaptation of the Hidformer multivariate time-series architecture. Its dual towers analyze temporal patterns and frequency-domain information separately, using recursive attention for sequence dependencies and linear attention…

The article presents a feature pipeline built around Bill Williams' fractals, defined as swing highs or lows confirmed by bars on both sides. It shows how these patterns can feed strength and validity measures, support and resistance levels, breakout flags,…

This article lays out a practical pipeline for deciding whether to develop and evaluate a reinforcement-learning trading system for gold. It begins with a supervised LightGBM baseline using triple-barrier labels and purged walk-forward folds to check whether…

The article explains ASHA, a metaheuristic optimizer that represents candidate solutions as water units moving across an objective-function landscape. It describes initialization, probabilistic moves toward random lower positions or the current best, an…

This article proposes representing a bar’s open and close prices as Cartesian coordinates, then converting them into polar coordinates: a radial distance and an angle. It explains how trigonometric transformations and derivatives can be calculated in MQL5,…

Artificial Multi-Social Search (MSO) is a population optimization method in which groups of particles move among sectors of a multidimensional search space. Each group tracks its center and best solutions, while particles and groups retain memories of…

This installment extends an MQL trading library’s pending-request system with requests to delete pending orders, change a position’s stop-loss or take-profit, and modify pending-order parameters. The functions are intended to let an expert advisor trigger…

This tutorial shows how to build MQL5 logic that identifies local highs and lows, then uses successive swing points to classify trend direction and detect possible double tops and double bottoms. It describes searching bar ranges for extrema, drawing lines…

The document gives a weighted formula for rating the quality of historical data used in one-minute strategy testing. It divides the available history into stages: bars before modeling begins, bars modeled on the nearest timeframe, bars modeled from minute…

In this interview, Automated Trading Championship participant Matúš German explains the design of his EA, which combines a moving average for trend direction with Williams Percent Range for entries and exits. Its position sizing method tracks hypothetical…

The article describes a MetaTrader 4 setup for intraday traders who want to issue order commands quickly while keeping a lightweight Expert Advisor. Control scripts pass commands and chart coordinates to the EA through terminal global variables; the EA…

The article explains the Alligator indicator as three shifted smoothed moving averages calculated from median price: the Jaw, Teeth, and Lips. It presents the indicator as a way to distinguish trending from sideways conditions and explains reading bullish or…

The article develops a spread between Si currency futures and RTS index futures, which it describes as usually moving in opposite directions. It fits a linear regression between the instruments, treats the difference from the resulting synthetic series as…

This installment describes adapting a MetaTrader position indicator so it can operate in a market replay or simulation environment that has no access to live terminal positions. The central design change is to remove direct position-data dependencies from…

The article explains how feature selection can reduce redundant or noisy inputs, simplify machine learning models, and potentially improve training efficiency and predictive performance. It groups techniques into filter methods, wrapper methods, embedded…

This article presents a charting script that draws the previous day’s candlesticks as a subdued overlay on the current day’s chart. The projected bars provide a visual comparison between current movement and the prior session’s range and structure, with…

This article describes adding a time-control layer to a MetaTrader 5 Expert Advisor. The proposed control defines a permitted operating interval for each day of the week, so the EA can restrict when it may open positions or submit orders. The schedule is…

This article shows how to automate sequential backtest windows in an MQL4 Expert Advisor. A time-check function gates trading to selected periods, with inputs for the start date, optimization length, test length, shift between windows, and window number. The…

This installment addresses a usability failure in a MetaTrader replay and market simulator: changing the chart timeframe reloads its indicators, leaving the mouse display in the wrong state and removing the controls. Recovery may depend on a later custom…

This article compares three historical price modeling modes in MetaTrader 4 strategy testing: open prices, control points, and every tick. The choice matters because a test based only on completed bars cannot represent all intrabar price paths, while…

This article shows how to wrap MQL5 indicator and price-series functions in compact helpers that resemble familiar MQL4 calls. It compares the direct MQL4 MACD value request with the MQL5 sequence of creating an indicator handle, checking it, and copying a…

This article explains how a MetaTrader indicator can rebuild and display the history of a position on a netting account, including entries, partial exits, and reversals. Since opposite-side deals reduce, close, or reverse a single symbol position, the…
