Bibliothèque de code source MQL4 et MQL5

News Trading Dashboard est un panneau d'information intégré au graphique (il n'effectue pas de transactions automatiquement) qui surveille la volatilité du marché en temps réel afin de détecter les moments de « pic lié à l'actualité » — ces fluctuations soudaines des cours qui surviennent lors de la publication de données économiques (NFP, IPC, décisions sur les taux d'intérêt, etc.).

Tests d'acceptation synthétiques déterministes pour la logique d'entrée des EA MT5, sans accès au marché, au compte ou aux ordres.

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.

Le « Day Trader Dashboard » est un panneau visuel de type Bloomberg pour MetaTrader 5 qui suit une fourchette de cours intrajournalière et signale lorsque le cours se trouve à l'intérieur de celle-ci (zone de consolidation) ou qu'il en est sorti. Il ne passe pas d'ordres : il s'agit d'un outil d'aide à la décision qui calcule la fourchette haut/bas à partir des barres récentes, trace ces niveaux directement sur le graphique et affiche un état en temps réel (analyse en cours / dans la fourchette / sortie de fourchette) dans un panneau thématique à mise à l'échelle automatique. Il prend en charge plusieurs instances indépendantes sur un même graphique, propose plusieurs thèmes de couleurs et supprime 100 % de ses objets lorsqu’il est désactivé.

Il s'agit d'un panneau de terminal de type « FX Dashboard » sur le graphique MT5, ainsi que de lignes tracées sur le graphique (EMA, Bollinger, Donchian).

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.

GDS Renko Replay Trainer is a free educational tool for practising manual decisions on historical Renko charts in MetaTrader 5. Load a historical interval, replay it forward and place virtual BUY or SELL trades. You can pause, advance one tick or move to the next completed Renko brick. Each virtual position has a stop loss and take profit, and the trainer records the results of your session. The tool builds fixed-size Renko bricks from historical Bid/Ask ticks, with a classic two-brick reversal. Future ticks are not used to draw the visible chart or execute virtual trades. Buy trades use Ask for entry and Bid for exit; sell trades use the opposite sides. Orders entered on the panel wait for the next replayed valid tick. Stops and targets are checked on every tick, including price gaps.

Built on Wyckoff Volume Spread Analysis (VSA) principles, it decodes smart money accumulation, distribution, absorption, and trend direction with zero repainting and a strict 2,000-bar performance limit.

Cet EA pour MT5 est un outil de diagnostic qui n'effectue pas de transactions, mais recueille et affiche les caractéristiques techniques du courtier et de l'environnement de trading. Le code est structuré en 4 blocs principaux : Collecte de données (CollectAll) : extrait des informations sur le compte (effet de levier, devise), sur le symbole (nombre de chiffres, spread, swap, volumes, niveaux de stop), la latence (ping) et le fuseau horaire (différence serveur-UTC). Calcule le swap en devise réelle. Échantillonnage (OnTick) : met à jour en temps réel les statistiques sur le spread (minimum, moyenne, maximum). Sortie : imprime les données dans le journal « Experts », les enregistre dans un fichier CSV et les affiche sur un panneau graphique sur le graphique (UpdatePanel). Aides : des fonctions telles que CalcSwapInCurrency et diverses fonctions *ToStr convertissent les données numériques brutes du courtier en chaînes de caractères lisibles.

Three position-sizing protections that do different things; confusing them is why so many accounts get wiped out: - ladder: one contract per X of balance, always applied as a CAP, even with manual lot sizing; - floor: below the minimum capital it does not trade; a new deposit is needed; - breaker: stops at X% below the peak, at any account size, and does not rearm by itself. What this library solves and almost none does: a deposit is not profit, and a withdrawal is not a loss. The breaker measures the drop against the balance peak. Untreated, a deposit made DURING a drawdown lifts balance and peak together, and the protection stops seeing the drop exactly when it would help. Here deposits and withdrawals shift the peak by the same amount. The peak is persisted to a file: a breaker that forgets the peak on a terminal restart is not a breaker. The demo simulates a deposit at the bottom of a drawdown. Run it with the deposit on and off and compare the "drop" column.

Four EAs writing to the same file, all with FILE_SHARE_READ|FILE_SHARE_WRITE, FileSeek(SEEK_END), FileWrite, FileClose. Looks correct. Every FileOpen returns success. No error in the log. And the lines vanish. Reason: FILE_SHARE_WRITE lets all four open at the same time. All four call FileSeek(SEEK_END) and get THE SAME offset, because none has written yet. All four write at the same position. Whoever closes last wins. Three lines vanish silently. In my case: 12 events expected, 8 in the file. The fix is to open EXCLUSIVELY (no FILE_SHARE_WRITE) and retry while another EA holds the file. And to shout in the log when the retries run out: a log that fails silently is worse than no log at all, because you trust it. The demo script reproduces both modes. To see the loss, drag it onto four charts at the same time with safe mode off and count the lines in the CSV. On a single chart the defect does not show up - which is why it passes in testing and breaks in production.

TimeCurrent() is not a clock. It is the stamp of the LAST TICK. Two consequences break robots in production: 1. It freezes. With no tick it does not move: illiquid instrument, end of session, unstable connection - and any rule based on it stops with it. 2. It steps backwards: on a symbol switch, a reconnection or a tick from another instrument, the value can go back. The case that cost me a whole protection: I compared the date of a daily decision with TimeCurrent() to reject an expired one. The server clock stepped back to the previous day, the comparison matched, and four EAs accepted YESTERDAY's decision as valid. The gate that should have failed closed failed open - without a single error in the log. Rule: TimeLocal() for timestamps, dates, day changes, expiry - all that must always move forward; TimeCurrent() for session hours and market data. The script measures the divergence in your environment and reports both symptoms live. Run it with the market closed.

Measures, hour by hour, how far a symbol travels and how much of that the spread takes away. Built for gold, works on any symbol, compares several side by side.

Detects the gold symbol whatever the broker calls it, reads the contract specification from the terminal instead of assuming it, and turns a risk in account currency into a lot size that is correct for that broker.

Opens a virtual bracketed trade on every M1 bar, walks it forward on the real tick history, and reports for a sweep of stop distances how often 1-minute OHLC modelling would score the trade the wrong way round.

Gold has a daily maintenance break on the CME. The first hour after it rises more than chance explains, in every calendar year of an 11-year sample - while every other hour of the day measures flat. One trade per session, a volatility-scaled server-side stop, no averaging or grid. Then my cost model turned out to be wrong. A real-tick backtest showed the true round-trip cost at the reopen is about 60 points, not the 19 my research had charged - the M1 bar spread field is a per-bar summary and understates it roughly threefold. Re-running 11 years at the corrected cost: +3.34 bps, t 7.40, 59.3% wins -> +1.60 bps, t 3.42, 50.8% wins The edge survives, at less than half its original strength. That second number is the real one. What it is not: about +3.3% a year with 4.6% drawdown, roughly one year in nine negative. At 0.01 lots that is ~130 a year - a figure that measures the position size, not the strategy.
