Panel that samples the spread once per second and shows it in points and in the symbol's natural unit (pips on FX, index points on index CFDs), with rolling min/avg/median/max, a session statistic since server midnight, the spread as percent of ATR, a hold-time alert and an optional CSV log. It never sends an order.

Marks the Asian session range, signals when London or New York sweeps one side of it and reverses, and keeps a scorecard of how every past signal ended in R, spread included. Non-repainting, with buffers ready for an Expert Advisor.

An intraday Smart Money Concepts EA for gold. It waits for price to sweep a recent swing high or low, confirms the reversal with a close through the sweep candle's body, and trades only with the H1 trend. Backtested on XAUUSD M15 over 2025 and 2026 at 1% risk per trade.

Free risk-based position size calculator built specifically for Gold (XAUUSD). Enter your account balance, risk percentage, entry price and stop-loss price - the indicator calculates the exact lot size, risk amount, stop distance, risk/reward ratio and potential profit, and draws entry, stop and take-profit lines on the chart. Contract size is read automatically from the symbol specification, so it works on any gold symbol without manual setup.

Hull Moving Average indicator displaying four periods on a single chart, colour-coded by direction (green for rising, red for falling, grey for flat). Implemented with a ring buffer and incremental running-sum math, so memory and CPU use remain constant regardless of chart history length. Buffer layout is documented and stable, making the indicator suitable for use with iCustom() from EAs. Supports 2, 3, or 4 Hull lines depending on configuration.

Protect Your Funded Account with Institutional-Grade Risk Monitoring. The #1 reason traders fail prop firm challenges is not a bad strategy; it is breaching daily drawdown limits. The AlphaQuant Prop Firm Daily Drawdown Dashboard is a free, high-visibility Expert Advisor

A real economic-calendar news filter that also works in backtests. Export the events once with a script, then block new entries around news both live and in the Strategy Tester. Fixes the one-hour DST shift of historical calendar times.

Educational MT5 hedging-account trade panel with risk sizing, spread protection, a persistent daily-loss lock, break-even and trailing stops.

TREND Follower (Daily) is a lightweight, development-oriented Expert Advisor (EA) created as a base trading architecture for research, learning, experimentation, and further development. The EA is intentionally designed around a simple concept: follow the market direction using the relationship between price and the Parabolic SAR. It is not presented as a fully optimized or finished trading system. Instead, it provides a clean and accessible foundation that developers can study, modify, test, and expand.

Account-wide MT5 risk protection EA for prop-firm and personal accounts. Monitors daily and overall drawdown, position losses, safety buffers, and automatically protects the account when configured limits are reached.

Spread histogram in a sub-window with current/avg/max/min stats, cost per trade, and threshold alerts for scalpers.

Educational MT5 EA: closed-bar EMA crossover entries, ATR-based stop loss and take profit, lot size from a fixed percent of equity via OrderCalcProfit, spread filter, magic-number isolation and server return-code checks. A clean template for building risk-controlled EAs. No profit claim.

Numbers every candle of the current trading day starting at the cash open of Frankfurt, London, New York or Tokyo. The anchor is converted from exchange local time to broker server time with automatic daylight saving, so the first candle after the open is always number one, in summer and in winter.

Professional Utility EA for prop firm risk management. It features daily equity monitoring, phased mitigation of losing positions, and absolute hard stops via a self-healing graphical dashboard.

Works out the lot from your risk percent and the stop distance, then opens the trade with the stop loss and take profit already attached. Never trades by itself.

Classifies the market with ADX, the Hurst exponent and lag-1 autocorrelation, routes each bar to a breakout module or a mean-reversion module, and keeps a separate win rate ledger for each regime with a Wilson 95% lower bound, so you can see which half of it is actually working.

Scores every setup type in your EA on its own record instead of lumping them into one equity curve. Rebuilds itself from the account's deal history on init so a restart cannot wipe the record. Prints a Wilson score lower bound next to the raw win rate so a three trade hot streak stops looking like an edge.

Position size from a risk amount, computed from the symbol's real tick value, tick size and volume step rather than an assumed pip value. It always rounds volume down, and when your risk is smaller than the minimum lot it says so and reports what that lot actually costs. No terminal state, so the sizing logic is testable offline - a 41-assertion test script is included.

Heiken Ashi ATR Blend combines smoothed Heiken Ashi candles, ATR-based volatility filtering, and fast/slow EMA trend confirmation to identify potential trend-change signals.

Closes losing positions early, before the full stop-loss, when a rule says the trade is not coming back: adverse move beyond N x ATR, too long in loss, EMA trend flipped, RSI against the position, or a money cap. Never touches a position in profit. Observe-only mode journals what would be closed without closing anything. Every exit is written to CSV with the rule, the age and the maximum adverse excursion, so the rules can be tuned from data.

Enforces your own risk rules on every position, whether opened by hand or by another EA: shows the lot size that matches your risk, locks the account for the day after a set loss, caps open positions, trims positions that risk more than allowed, and adds a stop-loss to any position opened without one.

Strict risk management utility for prop-firm challenges. Automatically monitors your entire account to prevent daily and max drawdown failures. It acts as a safety buffer against spread spikes and revenge trading by instantly closing all positions and pending orders before your evaluation is terminated.

Free MT5 position risk monitor displaying stop-loss risk, account risk percentage, positions without SL and individual position risk directly on the chart.

Free neon-style MT5 account dashboard displaying balance, equity, floating P/L, daily realized P/L, win rate and open positions directly on the chart.

GDS Renko Canvas + Donchian is a compact educational indicator for MetaTrader 5. It renders classic fixed-size Renko bricks on a single CCanvas bitmap layer and overlays a Donchian Channel calculated directly from completed Renko bricks. The horizontal axis represents Renko sequence rather than time. The internal builder uses incoming BID ticks and the classic two-brick reversal rule. The Donchian Channel is causal: for each newly completed brick, the channel is calculated from the previous N completed Renko bricks only. The current brick is excluded from its own channel calculation.

GDS Renko Brick Statistics is a compact educational indicator for MetaTrader 5 that builds classic fixed-size Renko internally from BID ticks and summarizes the behavior of the most recent completed Renko bricks.

A compact educational indicator for MetaTrader 5 that renders classic fixed-size Renko bricks on a single CCanvas bitmap layer and overlays Bollinger Bands calculated directly from completed Renko closes. The horizontal axis represents Renko sequence rather than time. The internal Renko builder uses incoming BID ticks and the classic two-brick reversal rule. Bollinger Bands are calculated only from completed Renko bricks; the forming brick is never used in the band calculation.

GDS Renko Bollinger 4-Mode Demo EA is a free educational Expert Advisor for MetaTrader 5. It demonstrates four different ways to combine classic fixed-size Renko bricks with Bollinger Bands inside one standalone EA. The EA builds four independent internal Renko streams from incoming BID ticks. Each mode has its own Renko brick size and its own Bollinger settings. Signals are generated only when a Renko brick is fully completed. Bollinger Bands are calculated causally from previous completed Renko closes, so the current brick is excluded until after its signal check.

A small educational Expert Advisor showing how Wilder's ADX and Directional Movement can be calculated directly from completed classic Renko bricks. The EA builds fixed-size Renko internally from BID ticks. No offline charts, custom symbols, DLLs or external indicators are required. +DI, -DI and ADX are updated only after a Renko brick has been completed.

GDS Renko Canvas is a compact educational indicator showing how a classic fixed-size Renko chart can be rendered directly in MetaTrader 5 with the standard CCanvas class. The indicator builds Renko bricks from incoming BID ticks and displays only completed bricks. Continuation requires one brick, while a reversal follows the classic two-brick rule. Unlike object-based Renko overlays, the visible chart is drawn on a single Canvas bitmap layer. This keeps the chart object list small and makes redraws on resize straightforward.

GDS Renko Dual MA Demo EA is a small educational Expert Advisor for MetaTrader 5. It shows one simple way to combine classic fixed-size Renko bricks with two simple moving averages calculated directly from completed Renko closes.

Tick-driven scalper that only trades genuine statistical outlier price moves, sized and protected to survive real broker execution delay. Backtest results included below.

AurumNeuro Vanguard is an intelligent Expert Advisor (EA) specifically designed for XAUUSD / Gold trading, combining a hybrid Neural Risk Architecture with the Unified Market Dynamics Engine (UMDE).

This educational Expert Advisor demonstrates one simple way to trade momentum on Renko bricks in MetaTrader 5. Momentum is the difference between the latest completed Renko close and the close N bricks earlier, divided by the brick size. A crossing above the positive threshold produces a BUY signal; a crossing below the negative threshold produces a SELL signal. Staying beyond a threshold does not generate repeated signals. The EA builds classic fixed-size Renko internally from Bid ticks, with a two-brick reversal. Orders use the available market Bid/Ask rather than synthetic brick prices. If several bricks form on one tick, only a crossing on the final brick can trigger entry. There is one position at a time, with virtual take profit, virtual stop loss, a maximum holding time, a cooldown and a spread filter. No external indicator, DLL, custom symbol or offline chart is required.

PulseStrike Scalper - Statistical Burst Detection EA

EMTOrdersUtility is a Real-Time Trade Monitor & Symbol Changer Utility designed for active traders who demand Real-Time visibility into their open positions across multiple financial instruments.

Ranks the current period's range-so-far against the full historical distribution of past ranges — a true percentile, not just a comparison to the average like ADR% — and flags statistical compression or expansion on a compact live panel with a percentile gauge.

A library of 24 MQL5 classes that watches a prop-firm rulebook -- drawdown, daily loss, payout consistency, minimum trading days, news blackout -- against any account, and flattens on breach without ever opening a position of its own.

MSNR KeyLevels MultiTF draws Malaysian SNR key levels from M5, M10, M15, H1, H4 and D1 at the same time, on any chart you have open. A built-in control panel lets you switch each timeframe on and off with a single click, so you go from a clean chart to full higher timeframe context in a second, and back again just as fast.
