A lightweight MT5 chart indicator that displays live broker and symbol trading specifications including spread, tick size, tick value, volume limits, stop level and freeze level.

Calculates a non-repainting Nadaraya-Watson envelope using Gaussian smoothing and marks price crosses beyond the upper and lower bands with arrows.

A draggable MT5 risk calculator that converts the selected entry and stop distance into a broker normalized position size using tick size, tick value and account risk.

A read only MT5 script that reports broker symbol specifications, volume limits, price settings, execution modes, trading permissions, margin requirements and estimated profit values.

Market Structure & Smart Trade Tracker (MT5) An advanced all-in-one Smart Money Concepts (SMC) indicator that combines automated market structure mapping, momentum heatmap candles, and institutional trade execution tracking.

Adaptive MACD is a dynamic momentum indicator that adjusts its smoothing based on market conditions. It calculates a Pearson correlation coefficient between price and bar index over a user-defined period, then uses the resulting R² to blend two different MACD coefficient sets. This makes the MACD line more responsive during strong trends and smoother in sideways markets. The indicator plots a color-coded histogram (strong/weak bullish/bearish) and an optional auto-contrast MACD line that adapts to the chart background. Inputs allow customization of the R² period, fast/slow lengths, signal period, and colors. Suitable for trend-following and detecting momentum shifts.

AMA_EntrySignal_Projekt_EN - Indicator WHAT IT IS An adapted/English edition of the AMA_EntrySignal_V2.mq5 indicator The indicator produces BUY/SELL entry signals, exit signals and a momentum-fade exit arrow, and shows an on-chart info panel with market state and trading statistics.

Market Replay Tool is an MT5 utility that seamlessly merges a Market Replay simulator with interactive TradingView-style Long & Short drawing tools. It allows traders to backtest strategies on historical data with adjustable playback speeds, while effortlessly mapping out risk-to-reward setups using dynamic, draggable entry, stop-loss, and take-profit visual boxes directly on the chart.

The script retrieves your broker’s actual spread from the ‘spread’ field of the M1 bars and displays the median, the 90th and 99th percentiles in price units, in pips and as a percentage of ATR, and also exports the average and maximum spreads for each hour of the day to a CSV file. This is needed to test strategies against the actual costs on your account, rather than against a ‘typical’ spread estimated from memory.

Measures whether a drawing indicator repaints, instead of asserting that it does not. The invariant: once a bar has closed and been processed, no object drawn on it may ever change - not move, not recolour, not change its text, and not disappear. The script seeds a custom symbol with real history, attaches your indicator through a template, records every object, appends bars, forces a full recalculation, and compares object by object. Changes and disappearances are counted separately, because only a change means the claim is false. A run that compared nothing is reported as INCONCLUSIVE, never as a pass. Output is a CSV you can publish next to the number.

Support Resistance zig zag based is a Price Action indicator designed to automatically and dynamically map Support, Resistance, and transition areas (Flip Zones) on the chart. It focuses purely on clear price structure mapping and highlighting key bounce areas (SBR & RBS). It also includes an interactive dashboard to monitor real-time market bias.

Market Structure Shift (CHoCH) Bullish Setup (CHoCH ): Price breaks above the previous confirmed Lower High (LH), signaling a trend reversal from bearish to bullish. Bearish Setup (CHoCH ): Price breaks below the previous confirmed Higher Low (HL), signaling a trend reversal from bullish to bearish.

The Auto ZigZag Fibonacci Golden Zone indicator automatically detects the latest swing high and low, draws key Fibonacci retracement levels (50%, 61.8%, 78.6%), and highlights the Golden Zone between 61.8% and 78.6% as an optimal pullback entry area. The indicator includes a real-time dashboard, optional buy/sell signals, and full color customization. Works on all symbols and timeframes. Always test on a demo account before live trading.

Builds a horizontal volume histogram over a recent lookback window and marks the Point of Control and Value Area using the standard TPO/volume value-area expansion algorithm — not just POC ± a fixed offset. Refreshed once per new bar, drawn as a sidebar next to price.

XAUUSD M15 basket recovery EA with adaptive ATR spacing, LL/LH structure validation, dynamic RSI gating, crash detection, news filter, and smart trade trimming.

Asian range indicator with breakout levels for the London session. Entry arrows, alerts, push notifications. Optimised for XAUUSD M15.

Marks fractal swing highs/lows as liquidity levels, then flags the exact bar where price wicks beyond one and closes back inside — a liquidity sweep / stop hunt — with an arrow and an optional price label. Sweep checks run only on closed bars, so signals never repaint.

Neural Loss-Pattern Auditor trains a small feed-forward neural network, written from scratch in native MQL5, on closed-deal history to test whether behavioral and market-context features predict which trades are more likely to lose. It reports an accuracy uplift over a naive baseline, a probability-calibration table, a permutation feature-importance ranking, and a configurable A-F composite grade with recommendations. On first run it uses a built-in synthetic demo, so the output is visible immediately with no setup; switch one input to InpUseDemoData=false to analyze real account history instead. Pure MQL5: no external libraries, no Python, and no AI service of any kind.

Detects 3-candle Fair Value Gaps (price imbalances) and draws them as boxes that extend live until price trades back through the gap. Detection runs only on fully closed bars, so gaps never flicker in and out as the current candle forms.

An interactive GUI panel for MetaTrader 5 designed for manual traders and quant developers. It automates dynamic position sizing based on exact account equity risk percentage, features one-click order execution (Buy/Sell), instant BreakEven, Close All functionality, and continuous real-time Trailing Stop management.

Quantitative MT5 Expert Advisor that filters market noise using Chaos Theory and the Largest Lyapunov Exponent (LLE). Trades momentum EMA crossovers only during deterministic market regimes, with built-in ATR risk management.

Most reports give you one drawdown number - the worst one. This read-only script measures all three that matter on your own closed history: depth, duration and frequency. It prints the maximum drawdown with its peak, trough and recovery dates, the longest underwater period in days, whether you are at a new peak or how far below it and for how long, and a table of the deepest episodes with the days each took to recover. An episode is not a losing streak: it closes only when a NEW high is made, so a dip that never reclaims the old peak stays the same episode - which is what makes the duration column meaningful. Entry commissions are included and a partial close counts as one round turn, so the curve carries full cost. Optional percentage figures and CSV export. Deposits and withdrawals are excluded: this is the drawdown of your trading, not of your balance line.

simple coundown timer

Closes a basket of positions when its floating loss reaches a limit set as fixed money, a percent of balance, or a percent of equity. Scope filters by symbol or magic numbers, optional profit target, safe non blocking retries.

SMC Pullback marks swing highs and lows using the pullback definition instead of the usual 3-candle pattern. A high is confirmed only when price trades back through the low of the candle that made it — so every marked point is an actual rejection, and highs and lows always alternate. It evaluates closed bars only and never moves a marker once drawn, so it does not repaint. Two buffers expose the confirmed swing prices to an EA via iCustom.

Estimates the rolling Hurst exponent of price via rescaled-range (R/S) analysis and plots it as a color-coded oscillator that flags whether the market is currently trending, mean-reverting, or moving like a random walk.

A compact on-chart panel showing the current symbol's trend across several timeframes at once, each evaluated independently with its own Fast/Slow moving-average cross. No switching charts to check "what's H4 doing" — it's all in one place, color-coded.

A Fisher Transform oscillator built from statistical first principles — normalizing price into a bounded range, then applying a logarithmic transform to produce sharp, well-defined reversal signals instead of the gradual turns typical of conventional oscillators. Internal recursive state is handled through proper calculation buffers for reliable, correct behavior across backtests. From the article series "Making Custom Indicators for Beginners."

A custom SuperTrend indicator built from first principles, combining an ATR-based volatility band with a ratchet mechanism to produce a clean, non-repainting trend line. Internal recursive state is managed through properly registered calculation buffers, avoiding the state-loss bugs common in manually-managed array implementations. From the article series "Making Custom Indicators for Beginners."

Professional MQL5 indicator (separate window) that automatically scans multiple symbols and timeframes, detects the most recent valid Wolfe Wave patterns (bullish/bearish), displays them in an interactive dashboard, and allows one-click chart opening with full pattern drawing.

The Hybrid Microstructure EA is an advanced, high-frequency scalping Expert Advisor designed specifically for XAUUSD (Gold) on the M1 timeframe. Unlike traditional indicators that rely on lagging OHLC mathematics, this EA operates on Tick-Level Microstructure Dynamics—tracking tick velocity, volume-weighted average price (VWAP) deviations, and liquidity sweep rejections (stop hunts) executed by institutions.

Measures whether an entry signal actually beats transaction costs, before you spend weeks building an EA around it. Reports net result after cost, an honest t-statistic on non-overlapping samples, and a random control. Places no orders.

Tracks the Asian, London, and New York session ranges, locks each one at session close, and flags true liquidity sweeps — a wick that pierces a locked high or low and closes back inside it — with an arrow signal and a shaded reaction zone. Non-repainting, works on any symbol and timeframe.

A subwindow oscillator that flags thin-participation displacement bars as "liquidity voids" and scores 0–100 how quickly price re-fills each one, distinguishing fast-absorbed noise from levels still acting as real support or resistance.

A free, read-only MetaTrader 5 panel that converts your prop firm's daily reset rule (written in whatever time zone the firm uses) into your broker's actual server time, shows a live countdown to the next reset, and warns you before a daylight-saving shift moves the boundary by an hour. Sends no orders, reads no account data, display only.

Ranks the 8 major currencies by relative strength on a live on-chart panel, calculated from the average percentage change of every available cross pair — not just USD pairs — so weak/strong currencies are visible at a glance, independent of whichever chart you have open.

Converts the body-to-wick makeup of every candle into a bounded conviction reading, then smooths it into an oscillator that flags buyer/seller pressure and automatically marks divergence against price.

Tracks the rolling correlation between the current chart symbol and a chosen reference symbol, and flags the moment they decouple while their price spread is statistically stretched.
