1. The Core Tracking Engine (Alpha-Beta Filter)At its core, the indicator utilizes an Alpha-Beta filter—a lightweight, steady-state version of a Kalman filter designed to track position and velocity.Predictive Calculation: Instead of simply averaging past prices like an SMA or EMA, the engine calculates a predicted price based on current velocity ($v$).Error Correction:

Variable Configurations to TestScalper Setup: Try an $\alpha$ of 0.45 and a $\beta$ of 0.12. The dashboard cells will flash changes rapidly, reacting instantly to short-term pullbacks.Swing Configuration: Lower the values to an $\alpha$ of 0.15 and a $\beta$ of 0.02. The matrix cells will stabilize, ignoring intraday market noise and preserving a clear view of macroscopic trends.

The Apex of Algorithmic Grid & Kinetic Momentum. Welcome to the KCI Native Matrix Engine—a merciless, mathematically driven algorithmic behemoth built natively for MetaTrader 5. Engineered for High-Frequency Trading (HFT) environments, this EA strips away bloated standard libraries and operates directly at the server routing level.

The KCI-Directional Matrix (KCI-DX) is an advanced, physics-inspired analytical tool that extracts market kinematics by measuring price path length and volatility energy. Unlike conventional momentum tools, KCI-DX employs a dynamic Z-Score normalization combined with a Sigmoid activation function. This ensures the output is flawlessly bounded between 0 and 100, providing hyper-responsive trend strength identification and directional bias without distortion from historical extremes.

The KCI Volatility Distance is an advanced, adaptive algorithm meticulously engineered to map market momentum and trend direction with pure precision. Utilizing a proprietary matrix-based calculation, this tool dynamically filters out market noise and provides a strictly quantitative perspective on directional strength. Built with a highly optimized Object-Oriented Programming (OOP) core, it is designed for both visual trading clarity and seamless integration into Expert Advisors or Machine Learning modules, ensuring ultra-light CPU performance across multiple assets.

This indicator is a trend-momentum oscillator that tracks where price sits relative to its structural volatility channel using a normalized relationship between the Parabolic SAR and Envelopes.

P/L Calendar — Monthly Profit & Loss at a Glance. P/L Calendar shows you, day by day, exactly how your account performed this month — so you can spot your best and worst days, track your win rate, and see your trading rhythm without digging through the terminal's history tab.

Chart Navigator MT5 Light — a mini-chart for quickly navigating the price chart and instantly jumping to your markers on it

This Expert Advisor monitors the Stochastic oscillator to automatically close positions based on user-selected conditions: crossovers above overbought or below oversold, entry into overbought/oversold zones, or exit from those zones. Positions are filtered for closure by profit state (loss, profit, or both). An optional Test Mode enables basic entry signals when the %D line crosses configurable offset levels around the midline (50).

BBandsPsar is a custom hybrid indicator that fuses Bollinger Bands’ volatility framework with the Parabolic SAR’s trend-following logic. By integrating these two methodologies, it effectively reconciles market volatility with emerging trend dynamics within a single, cohesive tool.

A pure-MQL5 script that measures how robust a strategy's edge is to execution costs. It reads a Date,Profit,Volume CSV of closing deals and models each deal's cost as a fixed part plus a per-lot part. It prints the breakeven cost per deal, the cushion (the multiple of an assumed realistic cost at which the net profit reaches zero), the net profit and profit factor re-priced at the assumed cost, the share of winners the cost turns into losers, and a composite A+ to F cost-robustness score with recommendations. If no file is present it generates a reproducible sample and analyzes it, so the output is visible on the first run. No external libraries, no Python, no AI.

The KCI Embedded Sniper is an algorithmic trading solution designed for high-precision reversal entries. Unlike conventional Expert Advisors that rely on external indicator dependencies (which often suffer from thread desynchronization and latency), this EA features a fully embedded Kinetic Compression Index (KCI) engine. By transplanting the entire mathematical framework of the KCI—calculating Velocity Quotients, Kinetic Displacement, Energy Dispersion, and Phase Velocity—directly into the EA’s core logic, we have eliminated "asynchronous lag." The result is a lightning-fast sniper engine that validates market exhaustion (Singularity) and momentum extremes (Williams %R) with micro-second precision, operating solely on completed bars to ensure zero-repaint performance.

The Kinetic Compression Index (KCI) is a custom oscillator designed to detect market exhaustion and localized compression events. By calculating its kinematic metrics internally rather than relying on external standard indicator handles, the KCI reduces overhead and simplifies buffer management for Expert Advisor (EA) integration. This article details the mathematical foundation, system architecture, buffer mapping, and practical integration guides for developers looking to implement this tool in MetaTrader 5.

SMC/ICT market-structure indicator for MT5: swing highs/lows, BOS (continuation) and CHoCH (reversal) confirmed on close, Order Blocks, Fair Value Gaps, and QML (Quasimodo) levels. Every feature is toggle-able, with adjustable swing sensitivity and colors. Works on any symbol and timeframe.

Exports your closed positions for a configurable period to a CSV file for journal analysis in Excel or Google Sheets: entry and exit time and price (volume-weighted over partial fills), volume, result in points, commission, swap, net profit and trade duration.

Calculates the correct lot size for a planned trade from your risk (percent of equity or a fixed money amount) and stop-loss distance (points or a price level). Respects the symbol's contract specification - tick size and value, volume min/max/step - and estimates the required margin.

On-chart panel with the live spread of the chart symbol - current, minimum, average and maximum since attach - color-coded against your warning and danger thresholds, plus an optional alert when the spread stays at the danger level for N consecutive seconds (news and rollover spikes).

A small, dependency-light library that brings a Rust-style Result type to MQL5. Functions return a single value-or-error object instead of relying on the global GetLastError() state, so failures are explicit and impossible to ignore. Includes ResultValue (value types) and Result (pointer-held objects), an Error struct, early-return macros (TRY, RETURN_ON_ERROR, ...) and optional Then/Match/MapError callbacks.

Live pip value, risk-based lot sizing, custom volume risk analysis & open position P/L — all in one panel.
