Monday Dip EA is a quantitative, time-based long-only trading strategy designed primarily for major stock index CFDs (such as US500, UK100) with complete daily history. It operates purely as a time-restricted buy-on-dip system rather than a trend-following indicator.

A script for accounts that run several Expert Advisors or configurations. It aggregates the net result of each configuration (magic number, or magic number and symbol) per calendar day and measures how much each one contributes to the portfolio drawdown: drawdown added by leave-one-out, share of the worst drawdown, and Euler variance share. It prints verdicts, recommendations, and a heuristic A+ to F score. It runs out of the box on a built-in demonstration portfolio and is written in pure MQL5.

A manual-trade manager for MetaTrader 5: completed Renko bricks, configurable break-even and trailing Stop Loss, plus an on-chart Renko dashboard. No automatic entries.

The library reconstructs a complete MQL4-style order model on top of the native MQL5 Position, Order, Deal, and History APIs. This design allows legacy MQL4 Expert Advisors to operate with minimal code changes while preserving MQL5.

A lightweight, non-trading Expert Advisor that writes a JSON health heartbeat (connection, AutoTrading state, equity, daily P/L) and an equity log, so a VPS watchdog can detect frozen or disconnected terminals and alert you.

A rolling, Katz-style fractal dimension of price that collapses toward 1.0 during directional moves and rises toward 2.0 during choppy, range-bound action, giving traders a single number for how "trendy" the current market is.

Position size calculator for MT5. Drag the SL and TP lines on the chart and the panel shows the lot size for your risk %, the real risk after rounding, the reward and R:R. Never trades.

A momentum oscillator that relaxes back toward zero at a speed set by the current ATR relative to its own moving average, so decay speed adapts automatically to whether the market is calm or volatile.

Clean and efficient Anchored VWAP (AVWAP) indicator for MetaTrader 5. Calculates volume-weighted average price from a user-defined anchor date with optional volatility standard deviation bands.

Smart Money Concepts market structure on pullback swings: trend, BoS, CHoCH, IDM and liquidity sweeps. A level counts as taken only on a close — a wick through it is marked as a sweep (x) and relocates the swing. Self-contained, closed bars only.

Support and resistance channels built from price pivots and ranked by strength: each pivot inside a channel and each bar that touched it adds to its score. The strongest channels run across the whole chart, colored by where price is, with break arrows, pivot marks, two averages and alerts.

Exports bars to a CSV file that pandas.read_csv() loads without encoding, separator or date-format arguments: ISO 8601 timestamps, prices at the symbol's own digits, single-byte encoding. Two modes (last N bars or a date range) and a switchable separator for Excel.

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 what every buffer of an indicator holds - arrows, a line or a colour index - and labels the arrows on the chart with their buffer numbers. Works with compiled indicators without source code.

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

Before configuring a basket, see which target weights fit your broker's minimum lots. Portfolio Allocation Planner turns an explicit hypothetical notional budget and percentages into a chart table: minimum-lot notional, lots rounded down, calculated allocation, target shortfall and row status. Recalculate on demand, inspect row tooltips, paginate longer lists, and optionally export the displayed snapshot to CSV. No trades are sent and no account balance, equity or positions are read.

DailyLossGuard — Hard Daily Loss Protection (Prop-Firm Challenge Essential)

Reads the server clock from the symbol's own H1 history. The forex and CME week closes at 17:00 New York, so the server time of every weekly close gives the server's UTC offset for that week. Over 60 weeks it flags irregular closes, dates every clock change and tests it against the US and European daylight saving calendars, cross-checks TimeTradeServer minus TimeGMT, and lists the server time of the London, New York, Tokyo and Sydney opens for the coming weeks. Writes every close to CSV. Read only: no trade function, no DLL, no network.

Shows how much of the daily loss limit of a prop firm account is already used, and how much is left. Read-only indicator.

Measures how far your PC clock is from the trade server's clock, from the server time stamped on live ticks, and tells you how to fix it.

Session Levels draws the reference levels intraday traders watch most: Asian range, London and New York sessions, previous day and week high/low, daily VWAP, swing points and round numbers. Hover any level to read what it is and why it matters. Optional alerts when price breaks the Asian range or the previous day high/low.

Real-time multi-timeframe side panel mini-chart with smart color matching, independent price scale, and candle countdown timer.
