The article introduces DeMarker, an oscillator based on changes in successive highs and lows. It explains the calculation using moving averages of upward and downward price extensions and describes the indicator’s scale from zero to one. The proposed…

Momentum Pinball uses a daily LBR/RSI reading to set the likely direction for the next session, then uses the first hourly bar to define an entry and initial stop. A reading below 30 signals a potential buy day; a reading above 70 signals a potential sell…

The article describes a MetaTrader workflow for running an Expert Advisor on several symbols at once and consolidating the outcomes for visual comparison. It configures multiple terminal instances with separate tester settings, synchronizes their account and…

The article treats preprocessing as a tunable part of a machine-learning trading pipeline and compares transformations in a feedback-controlled strategy. Its baseline uses twelve input features without scaling; after an initial 90-day period, the controller…

The article introduces pending trading requests as a way to retry failed trade operations without blocking an expert advisor with a timed pause. A trading class can store a request, resume its normal work, and retry when the wait period ends. The same…

The article explains Extralonger, a neural network architecture designed to combine spatial relationships and temporal patterns in long-horizon forecasting. It motivates the method through an analogy between traffic networks and financial markets, where…

The article describes maintenance work on a MetaTrader replay and simulation system after a new application exposed performance and reliability issues. Its main design change is to improve encapsulation: buffer-writing logic is moved out of a general mouse…

The article explains how an associative array, or dictionary, stores objects under unique keys so a program can retrieve information by a value such as text or an enumeration instead of a numeric array index. It reviews arrays, nodes, and linked lists to…

The article presents a reusable structure for automated strategy logic by separating four actions: initiating long positions, initiating short positions, supporting existing longs, and supporting existing shorts. A moving-average example illustrates why…

This MQL5 tutorial describes a custom indicator that identifies swing highs and lows, classifies higher highs and higher lows or lower highs and lower lows, and uses those sequences to represent bullish or bearish structure. The example detects pivots by…

This article discusses how to assess Expert Advisors beyond attractive marketplace claims or a single optimized backtest. It flags warning signs such as sparse track records, asymmetric stop and target sizes, and position schemes that add exposure during…

This technical guide introduces MQL5’s vector and matrix types as tools for representing ordered numerical data and expressing linear algebra operations. It explains how to initialize vectors with preset values or a filling function, resize and copy them,…

The article introduces Fibonacci retracement as a charting method for marking potential support or resistance after a price move. It describes common retracement levels and the usual drawing direction: low to high after an uptrend and high to low after a…

The article explains four ways to measure information in the sequence of trade directions within a bar: Shannon entropy for symbol frequencies, plug-in entropy for repeated blocks, Lempel-Ziv complexity for compressibility, and Kontoyiannis entropy for…

This article explains how to combine discretionary chart analysis with automated monitoring in MetaTrader 5. A trader draws trendlines and explicitly synchronizes selected lines with an Expert Advisor, which tracks their changing price as time advances and…

The article describes an MQL5 system for identifying bullish and bearish Bat harmonic patterns from five swing points, labeled X, A, B, C, and D. It defines the pattern through their sequence and Fibonacci relationships: B retraces about half of XA, C…

The article explains momentum as a measure of price-change speed and trend strength, then shows two common calculations: subtracting a prior close from the current close, or dividing the current close by a prior close and multiplying by 100. It focuses on…

The document treats encoded candlestick types as symbols in an ordered sequence, then explains how permutations can enumerate possible multi-candle patterns. It distinguishes arrangements without repetition, counted by selecting and ordering distinct…

The article investigates whether Visa’s monthly Spending Momentum Index series can help classify future EUR/USD direction. It combines headline, discretionary, and non-discretionary spending measures with monthly price data, examines plots and correlations,…

The document describes how to connect a MetaTrader 5 Expert Advisor to a Discord channel through a webhook. It covers enabling platform web requests, configuring a Discord webhook, preparing JSON messages, escaping special characters, converting text to…

The document explains a genetic algorithm that represents each candidate solution as a chromosome of real-valued genes. It describes a population split between parent and offspring groups, fitness-based sorting, selection, crossover, mutation, and…

The article turns several short-term price observations associated with Larry Williams into independently testable strategies. Setups include buying at the open as a baseline, buying after one or several down closes, buying a measured pullback in an…

The article introduces Bollinger Bands as a moving average surrounded by volatility-scaled upper and lower bands. Unlike fixed-percentage envelopes, the bands widen when price variability rises and narrow when it falls. It explains their use in assessing…

This article presents a method for reducing sampling noise in correlation matrices used by multi-symbol trading systems. It explains that estimating many pairwise relationships from a limited return window can produce unstable eigenvalues and weights. The…
