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.

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.

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.

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.

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.

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.

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.

Spread Monitor is a simple information indicator for MetaTrader 5. It displays the current spread in pips in the form of a compact graphical panel with colour-coded indicators and a level bar.

The advisor opens trades when two moving averages (Fast and Slow) cross. It works on any instrument and timeframe.

MarketInfo is a simple information script for MetaTrader 5. It collects and logs key data for the current instrument: prices, spread, volatility (ATR), time remaining until the bar closes, statistics covering N bars, and trend identification.

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.

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.

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.

Time weighted average price of the running session, anchored at the cash open of Frankfurt, London, New York or Tokyo with automatic daylight saving. Every second counts the same, minutes without a tick carry the last price, and two bands show the time weighted standard deviation around the line.

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.

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.

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.

The Adaptive Kalman Trend Filter smooths price fluctuations to highlight the underlying market trend, adapting its responsiveness as market conditions change.

Tracks changes to 18 broker contract properties against a saved baseline, with before and after values, a chart panel and a local CSV audit trail.

Tests whether live closing deals still match the backtest of an Expert Advisor. A bootstrap-calibrated CUSUM detector raises an alarm and estimates when the drift began, a two-window check separates a short dip from a lasting decline, and an expectancy decomposition shows whether the win rate or the trade sizes changed. The script generates demonstration data on the first run and is written in pure MQL5.

Script that lists the global variables of the terminal with value, last access time and age, filtered by prefix, substring and age. It exports them to CSV, deletes the matching ones after a confirmation and a backup, and restores them from a CSV file.

H1 indicator that combines support/resistance confluence from H4, D1 and W1 with EMA trend alignment and candlestick confirmation. Shows non-repainting BUY/SELL arrows with ATR-based stop and reward/risk filtering.

A chart panel that shows the contract specification details that decide position size and trading cost (point value, spread cost, margin, swap, execution rules) in the account currency, warns about broker settings that silently break lot-size code, and exports the audit of every Market Watch symbol to CSV.

Asian, London and New York session high/low boxes with ICT killzone shading, breakout alerts and average-range statistics panel.

Measures whether an indicator repaints instead of trusting the claim. It re-reads the buffers of any custom indicator on bars that have already closed and counts every value that changes, appears or disappears, with the furthest shift back at which that still happens. Verdict per buffer on a chart panel, every event written to CSV.

Shows where stops are likely resting and which ones were just taken. Liquidity pools = confirmed swing highs and lows that price has not traded through yet, equal highs/lows (a bigger pool) and yesterday's high and low. When a bar trades beyond a pool it is marked as swept, and as "grabbed & rejected" if the same bar closes back inside. Non-repainting: a swing is used only after N closed bars on each side. The panel is a neon city drawn on a CCanvas: the price is a flying car, sell stops are towers below it, buy stops floating platforms above it, yesterday's levels golden billboards, a searchlight sweeps the sky and a ticker runs today's catch. Two buffers give the nearest active pool above and below for use in an Expert Advisor. Indicator only: it never trades.

Calculates position size and daily / max loss limits for prop firm accounts and shows them in a panel on the chart.

Gold EA that trades both directions: when the stochastic signal line turns, it places a stop order at yesterday's high or low, filtered by a Bollinger band. Self-contained, no custom indicators. Backtest on XAUUSD H1, July 2021 to September 2026: +245% on a 1,000 USD deposit at a fixed 0.01 lot, 23.9% maximum equity drawdown.

Audits the bar history your terminal actually holds, which is the history every backtest and every indicator reads. Six checks per symbol: impossible OHLC values, broken bar times, bars missing while the broker's own session table says it was quoting, empty and flat bars, bars that disagree with the broker's own M1 series, and spread sanity. The headline figure is session coverage, not a grid percentage that mostly measures how many weekends you audited. Every finding goes to CSV with its bar time, and the audited bars plus the session table can be dumped so the whole report can be recounted by something other than this tool.

The Market Behavior Analyzer is a practical indicator designed to make market structure easier to read directly from the chart. It identifies significant swing points, classifies them as Higher Highs, Higher Lows, Lower Highs, and Lower Lows, and tracks the movement between them in pips. It also provides a Market Story panel and an interactive Swing Inspector for examining impulses, pullbacks, retracements, swing duration, and the developing market structure.

Shows the range of every bar in points, its moving average (SMA or EMA) and a suggested stop distance (average x factor). A stop tighter than the typical bar range gets taken out by ordinary noise; the indicator makes that threshold visible in points, the same unit a stop loss is set in.

Shows the day's result against the daily and max loss limits of a prop firm account, with a warning alert, in a panel on the chart.

Resamples your closed trades 10,000 times to show whether your average trade is an edge or could still be luck: the 95% range of the average and the chance it is below zero.

Opening Range Breakout EA template with built-in account protection. Marks the high and low of the first N minutes after the session open and places OCO stop orders above and below the range. Includes risk-based position sizing, daily loss limit, maximum drawdown limit, ATR range filter, trade direction filter, and protection against positions carried overnight. All session times are configurable inputs. Educational template, not a profit-guaranteed system. Test on demo before any live use.

A specified moment in time can be analyzed through multiple synced timeframes from 1 host chart for a symbol.

Audits the tick history that 'Every tick based on real ticks' backtests replay. Five checks per symbol over the last N days: impossible and crossed quotes, timestamps that run backwards or repeat, one-tick price reversals sized in multiples of the symbol's own median spread, silences inside the broker's declared quote sessions, and minutes where the ticks and the M1 bars disagree. Every finding goes to CSV with its millisecond timestamp, and the tool prints its own arithmetic so the report can be recounted. Read only: no trade function, no DLL, no network.

A free, fully open JPN225 (Nikkei 225) EA for M15. Buys when price leans up, momentum isn't stretched and volume is quiet. Backtest 2022 to 2026: profit factor 1.68, +18.5% a year, passed 15 stress tests. Flat by 17:00.

Measures market activity from the waits between quotes. An ACD model with the daily rhythm removed gives one ratio per tick: 1 is normal, 2 twice as busy.

One panel for the rules of a prop firm challenge: daily loss, maximum loss (static or trailing), profit target, minimum trading days and the best-day (consistency) rule. For each one it shows how much is used and how much room is left, in money. "One more trade" tells you the largest lot size that still keeps a stop-out inside the room left today and in the max-loss room. Read-only: it never opens, changes or closes a trade. The presets hold typical values; firms change their rules, so check yours and use the Custom preset. Built on the ATS Risk Library (ATS_RiskLib.mqh, included).
