Complete deep learning library in pure MQL5. Build, train and deploy neural networks natively in MetaTrader 5. No DLLs, no Python, no external APIs.

This EA implements a range breakout trading strategy. It calculates a price range between start and end times defined by the user, draws a visual rectangle on the chart to mark the high and low of that range, and then monitors price action after the range closes. If the market breaks above the range high, it opens a buy trade; if it breaks below the range low, it opens a sell trade.

The indicator identifies areas of imbalance (Fair Value Gaps) on the chart and signals them with an arrow when the price returns to them. It is suitable for Gold, Forex and any liquid instruments on timeframes ranging from M5 to H4.

Allows to monitor spread and swaps!

Displays the current bid-ask spread in points and pips directly on the chart, with live tracking of session minimum, maximum and average spread since the indicator was attached. Color changes to alert when spread exceeds a user-defined threshold.

Multi-indicator EA for Gold (XAUUSD) and Silver (XAGUSD): RSI, ADX and MA signals, adaptive ATR trailing stop and built-in capital protection.

Expert Advisor for testing the Turnaround Tuesday hypothesis. If Monday closes bullish, a Sell position is opened on Tuesday. If Monday closes bearish, a Buy position is opened. The EA supports an ATR-based filter, ATR-based Stop Loss and Take Profit levels, as well as position sizing using either a fixed lot size or percentage risk.

An econometric price-space indicator that utilizes the Ornstein-Uhlenbeck stochastic process to mathematically estimate the asset's true driftless equilibrium and its speed of mean reversion.

Instead of having to analyze each pair individually, you can see at a glance what are the most promising pairs according to your own criteria.

Account-level daily loss guardian: when your daily loss reaches a configurable trigger, it closes all positions and pending orders and keeps the account flat until the next daily reset. Limits in percent or money, configurable reset time (server time), draggable visual panel with live gauge, and manual CLOSE ALL / LOCK buttons with click-to-confirm. Works on any broker, symbol, account size and currency — hedging and netting, no DLLs.

This Expert Advisor combines an ADX-based trend strength filter with an EMA pullback entry technique, using ATR for dynamic stop loss and take profit sizing. It is designed for trading a single symbol with one position open at a time.

Daily Range Tracker — Live Today's Range vs Average Daily Range. Daily Range Tracker shows you, at a glance, how much of the symbol's typical daily movement has already happened today — helping you judge whether the day still has room to run or is already exhausted.

A small educational MetaTrader 5 indicator that marks confirmed swing highs and lows and labels market structure as HH, HL, LH and LL.

A native MQL5 script that analyzes the structure of an account's drawdowns, not just the single "maximum drawdown" figure. It reads a daily equity curve (Date,DailyPnL CSV), rebuilds the underwater curve, and splits it into individual drawdown episodes with their depth, duration and recovery time. It then reports the Ulcer Index, Pain Index, Recovery Factor and time spent underwater, and combines them into a single resilience score (A+ to F) with recommendations, printed in the Experts tab. No external libraries; if no file is found it generates a sample curve so it runs out of the box.

A native MQL5 script that measures how concentrated a strategy's profit is — whether the edge is broad or rests on a few lucky trades. It reads a per-trade CSV (Date,Profit) and reports the share of net profit from the largest trades, the Gini coefficient of the winners, a concentration profile, a survival test that removes the best few trades and recomputes net profit and profit factor, and the largest single day versus a configurable consistency limit, combined into a concentration-and-consistency score (A+ to F) with recommendations. If no file is found it generates a sample set, so it runs out of the box. No external libraries, no Python, no AI. The helper ExportTrades.mq5 writes the file from your trade history.

A lightweight educational MetaTrader 5 indicator that maps Premium, Equilibrium and Discount areas from a selected market range.

Spread calculator is created to display the current spread on any currency pair on the chart.

An educational MT5 indicator that builds support and resistance as price zones from confirmed pivots. Nearby reactions are merged using ATR-based distance, then ranked by repeated tests, rejection strength and recency. Only the strongest zones are displayed to keep the chart readable.

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.

Multi-timeframe Support & Resistance zone scanner with strength rating and instant alerts — M15, H1, H4, D1.

A read-only on-chart panel that tracks your account against a daily-loss limit and a max-drawdown limit, with color-coded OK / WARNING / DANGER status. Monitoring only - it does not place, modify or close any orders.

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.

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.

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.

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.
