The Weekend Gap Statistics & Distribution Analyzer is a purely analytical MQL5 indicator designed to evaluate the historical behavior of weekend price gaps. It scans chart data to calculate gap closure rates and measures the adverse excursion (drawdown) experienced before a gap successfully closes. By providing statistical distributions—including the 70th and 90th percentiles of adverse heat—this tool enables traders to make data-driven decisions. It moves beyond simple averages, allowing traders to properly assess risk, filter out low-probability instruments, and optimize stop-loss placement when fading weekend gaps.

A quantitative Information Theory engine that calculates the Shannon Entropy of price distribution to mathematically measure market randomness and algorithmic predictability.

An aerospace-grade state estimation algorithm that dynamically filters out market noise and manipulation wicks to reveal the true underlying execution price with zero static phase-lag.

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

Triple-barrier labeling pipelines frequently use an arbitrary constant (0.5–1.0%) or a legacy spread assumption as the min_ret threshold. A threshold set below the actual round-trip transaction cost causes the pipeline to label cost-driven noise as tradeable signal. The labeled dataset then systematically overstates edge, and any model trained on those labels overfits to an artifact of the labeling scheme rather than to genuine market structure. TransactionCostCollector.mq5 is a standalone script that resolves the data-collection step of this problem.

Script to set Stop Loss on every open position based on a target loss in the account's currency (e.g. $50 per position). Works on any deposit currency and any forex symbol. Validates broker stops/freeze levels. Currency conversion handled automatically.

A multi currency multi symbols super trend dashboard

Asian Session Breakout identifies the price range formed during the Asian trading session and monitors how price behaves after that session ends. The Asian High and Asian Low remain extended until the end of the broker trading day. This makes the range useful as an intraday support-and-resistance zone during the European and US sessions. A compact dashboard displays the current range values, configured session time, breakout status, breakout confirmation method, and confirmation timeframe. The indicator does not open or manage trades. It provides market structure and breakout information for discretionary trading or EA development.

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.

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.
