Libreria di Codici Sorgente MQL4 e MQL5

Probability of Backtest Overfitting (PBO) of an MT5 optimization by combinatorially symmetric cross-validation. Every pass sends its daily results as a frame, and the PBO is computed when the optimization ends.

Block bootstrap of daily results: how deep the drawdown of an account or strategy can get over the next months, with percentiles and a seeded generator for repeatable runs.

Portfolio weights from the returns of symbols or Expert Advisors: inverse volatility, risk parity, hierarchical risk parity, minimum variance, maximum diversification, Ledoit-Wolf covariance.

Reads a Strategy Tester report saved as HTML into its deals, closed trades, net profit and balance drawdowns, for comparing, combining or exporting backtests.

Automated checks of an Expert Advisor on a live demo chart (restart, second copy, server history, chart button) with a PASS/FAIL report.

Single-header account lock for MT5 EAs: licensed account numbers, optional demo allowance, expiry date, tester bypass. Licence compiled in with #define. No DLL.

Risk tool for prop firm accounts: closes all positions and blocks new trades when the daily loss or max loss limit is reached. Never opens trades on a live chart.

Line Master is a trend-following indicator for MetaTrader 5 that displays fast and slow dynamic price lines to help traders identify market direction and potential trend changes. Blue represents a bullish trend, while red represents a bearish trend. Visual markers highlight changes in the indicator's trend state. The indicator includes adjustable Fast Length and Slow Length parameters, allowing traders to customize its sensitivity. It can be used on forex, gold (XAUUSD), indices, and other MT5-supported markets. For better results, combine its signals with price action, support and resistance levels, and proper risk management. Signals are not guaranteed and should be confirmed before entering a trade.

Assegna un punteggio a ogni tipo di configurazione del tuo EA in un registro separato, anziché raggrupparli in un’unica curva di equity. Si ricostituisce automaticamente a partire dalla cronologia delle operazioni del conto al momento dell’avvio, in modo che un riavvio non possa cancellarne la cronologia. Visualizza un limite inferiore del punteggio di Wilson accanto alla percentuale di vincita grezza, in modo che una serie positiva di tre operazioni non sembri più un vantaggio competitivo.

I numeri indicano ogni candela della giornata di negoziazione in corso, a partire dall'apertura del mercato a Francoforte, Londra, New York o Tokyo. Il punto di riferimento viene convertito dall'ora locale della borsa all'ora del server del broker con adeguamento automatico all'ora legale, quindi la prima candela dopo l'apertura è sempre la numero uno, sia d'estate che d'inverno.

Spread Monitor is an MQL5 Expert Advisor that draws a colour-coded panel on the chart. The panel shows the current spread of the attached symbol in points, along with the average, minimum, and maximum over a rolling history. It also counts how many stored samples exceeded a warning level, and turns the status row red when the current spread is above that level. The utility does not place orders. Inputs control the warning level, the history size, the refresh interval, and the panel position. Panel objects are removed when the EA is detached.

EA MT5 didattico: entrate basate sul crossover dell'EMA su barre chiuse, stop loss e take profit basati sull'ATR, dimensione del lotto calcolata in base a una percentuale fissa del capitale tramite OrderCalcProfit, filtro dello spread, isolamento dei numeri magici e controlli dei codici di ritorno del server. Un modello pulito per la creazione di EA con controllo del rischio. Nessuna garanzia di profitto.

Istogramma dello spread in una finestra secondaria con statistiche relative a valori attuali, medi, massimi e minimi, costo per operazione e avvisi di soglia per gli scalper.

Measures, on the chart's own history, how often a bar takes out the prior high or the prior low after bullish and after bearish bars, at up to five levels spaced by the average range. Each level carries a probability bar, and a table scores the favored side over all bars and over the last 200.

Classifica il mercato utilizzando l'ADX, l'esponente di Hurst e l'autocorrelazione con ritardo 1, indirizza ogni barra verso un modulo di breakout o un modulo di ritorno alla media e tiene un registro separato della percentuale di successo per ciascun regime con un limite inferiore al 95% secondo Wilson, in modo da poter vedere quale delle due metà sta effettivamente funzionando.

Calcola il lotto in base alla percentuale di rischio e alla distanza dello stop, quindi apre la posizione con lo stop loss e il take profit già impostati. Non effettua mai operazioni in modo autonomo.

A chart panel for MT5 that places Buy Limit, Sell Limit, Buy Stop and Sell Stop pending orders with one click.

Pure native MQL5, no DLLs, no external dependencies.

Tre meccanismi di protezione per il dimensionamento delle posizioni che funzionano in modo diverso; confonderli è il motivo per cui così tanti conti vengono azzerati: - ladder: un contratto ogni X del saldo, applicato sempre come limite massimo (CAP), anche con il dimensionamento manuale dei lotti; - floor: al di sotto del capitale minimo non effettua operazioni; è necessario un nuovo versamento; - breaker: si attiva all’X% al di sotto del picco, indipendentemente dalle dimensioni del conto, e non si riattiva automaticamente. Ciò che questa libreria risolve e che quasi nessuna altra fa: un versamento non è un profitto, e un prelievo non è una perdita. Il «breaker» misura il calo rispetto al picco del saldo. Se non gestita, un'operazione di deposito effettuata DURANTE un drawdown fa aumentare contemporaneamente sia il saldo che il picco, e la protezione smette di rilevare il calo proprio nel momento in cui sarebbe utile. In questo caso, depositi e prelievi spostano il picco dello stesso importo. Il picco viene salvato in un file: un «breaker» che dimentica il picco al riavvio del terminale non è un «breaker». La demo simula un deposito al punto più basso di un calo. Eseguila con il deposito attivato e disattivato e confronta la colonna «calo».

La dimensione della posizione viene calcolata in base all'importo di rischio, determinato dal valore reale del tick del simbolo, dalla dimensione del tick e dall'incremento di volume, anziché da un valore ipotetico del pip. Il volume viene sempre arrotondato per difetto e, quando il rischio è inferiore al lotto minimo, il sistema lo segnala e indica il costo effettivo di quel lotto. Non è richiesto un terminale, quindi la logica di calcolo delle dimensioni è verificabile offline: è incluso uno script di test con 41 asserzioni.

Session Range Breakout draws the high and low of up to three intraday sessions (Asia, London and New York by default) and extends each level to the right with optional H/L labels and a range rectangle. Session hours, names and colours are configurable in server time. Optional popup, sound and push alerts fire when a bar closes outside a session range. The levels are fixed once the session closes, so the drawing does not repaint. The indicator draws chart objects only and never opens trades.

Calculates the Strategy Tester report statistics from the deal history, including Z-Score, AHPR, GHPR, LR Correlation and LR Standard Error, which TesterStatistics() does not return. Checked value by value against the tester.

ICT kill zones (Asian, London, New York, London Close) at the right New York hours on any broker, with US and EU summer time. High / low boxes, levels until price takes them, midnight open. Alerts and buffers for EAs.

Marks the order block behind each break of market structure (the last opposite candle before the move), tracks when it is used and turns failed blocks into breaker blocks. No repaint. Alerts and buffers for EAs.

An include file that writes real Excel workbooks (.xlsx) from MQL5 without DLLs: several sheets, numbers, text and real Excel dates, a frozen bold header and filters. Example script: the account deals and the daily results to Excel.
