MQL5 Source Codes of Technical Indicators for MetaTrader 5

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.

Draws ICT structure on the chart (liquidity pools, sweeps, market structure shift, fair value gaps) from closed bars only, adds a trade plan for every confirmed setup and keeps an honest statistics panel of what those setups did on your symbol. Analysis only – it does not trade.

One panel for the rules of a prop firm challenge: daily loss, maximum loss (static or trailing), profit target, minimum trading days and the best-day (consistency) rule. For each one it shows how much is used and how much room is left, in money. "One more trade" tells you the largest lot size that still keeps a stop-out inside the room left today and in the max-loss room. Read-only: it never opens, changes or closes a trade. The presets hold typical values; firms change their rules, so check yours and use the Custom preset. Built on the ATS Risk Library (ATS_RiskLib.mqh, included).

The Trend BOSS Indicator identifies regimes such as trending, ranging or volatile using a Bag-of-SFA-Symbols (BOSS) classifier. Gate your strategies behind specific regimes or use the indicator to identify various market conditions.

Measures market activity from the waits between quotes. An ACD model with the daily rhythm removed gives one ratio per tick: 1 is normal, 2 twice as busy.

Extrapolator fits a sum of sinusoidal harmonics to the recent price history and extends the fitted curve to the right of the last bar as a forecast.The forecast is a mathematical extrapolation of past cyclical behaviour, not a guarantee of future price movement. The last part of the line is redrawn while the current model bar is forming, and the fitted curve changes with each refit.

A specified moment in time can be analyzed through multiple synced timeframes from 1 host chart for a symbol.

Shades the chart background by volatility regime (Compression, Normal, Expansion) based on the percentile rank of the current ATR. Shows the current regime on the chart, alerts on regime changes and exposes buffers for Expert Advisors.

Draws Asian, London and New York session range boxes and marks liquidity sweeps: a closed bar that wicks beyond a completed session's high or low and closes back inside. Non-repainting arrows, extended session levels, alerts and iCustom-ready buffers.

ICT killzones for MetaTrader 5: Asia, London and New York sessions drawn in New York time with automatic daylight-saving conversion, session highs and lows carried forward until price takes them, previous day, week and month levels, opening prices and time markers. One file, no DLL.

Arixis Market Regime Map is a non-repainting MT5 indicator that classifies market conditions as Trend Up, Trend Down, Range or Transition using price efficiency, normalized slope, volatility, market structure and multi-horizon agreement.

Shows the day's result against the daily and max loss limits of a prop firm account, with a warning alert, in a panel on the chart.

The Market Behavior Analyzer is a practical indicator designed to make market structure easier to read directly from the chart. It identifies significant swing points, classifies them as Higher Highs, Higher Lows, Lower Highs, and Lower Lows, and tracks the movement between them in pips. It also provides a Market Story panel and an interactive Swing Inspector for examining impulses, pullbacks, retracements, swing duration, and the developing market structure.

Calculates position size and daily / max loss limits for prop firm accounts and shows them in a panel on the chart.

A free open-source MT5 utility for analyzing historical trading performance beyond Profit Factor.

Shows where stops are likely resting and which ones were just taken. Liquidity pools = confirmed swing highs and lows that price has not traded through yet, equal highs/lows (a bigger pool) and yesterday's high and low. When a bar trades beyond a pool it is marked as swept, and as "grabbed & rejected" if the same bar closes back inside. Non-repainting: a swing is used only after N closed bars on each side. The panel is a neon city drawn on a CCanvas: the price is a flying car, sell stops are towers below it, buy stops floating platforms above it, yesterday's levels golden billboards, a searchlight sweeps the sky and a ticker runs today's catch. Two buffers give the nearest active pool above and below for use in an Expert Advisor. Indicator only: it never trades.

Quickly view each and every individual market's open and close times. Very important for short term scalping. I own the copyright, if anyone modifies or uses this it must stay free. Comments and feedback welcome.

Shows the real spread for each server hour, measured from your broker's own tick history: median and 90th percentile per hour, optional cost as a share of your stop and per lot, and CSV export.

A chart panel that shows the contract specification details that decide position size and trading cost (point value, spread cost, margin, swap, execution rules) in the account currency, warns about broker settings that silently break lot-size code, and exports the audit of every Market Watch symbol to CSV.

H1 indicator that combines support/resistance confluence from H4, D1 and W1 with EMA trend alignment and candlestick confirmation. Shows non-repainting BUY/SELL arrows with ATR-based stop and reward/risk filtering.

Tracks changes to 18 broker contract properties against a saved baseline, with before and after values, a chart panel and a local CSV audit trail.

The Adaptive Kalman Trend Filter smooths price fluctuations to highlight the underlying market trend, adapting its responsiveness as market conditions change.

iFVG Indicator With Signals

Marks impulse candles: body at least ATR x multiplier, body at least a set share of the candle range, close near the extreme, optional tick volume confirmation. Green arrow below a bullish impulse, red above a bearish one. Closed bars only, no repainting. Signals are in the two buffers so an Expert Advisor can read them with iCustom.

Open-source MT5 indicator for confirmed market structure, volumetric order blocks and estimated buy/sell activity.

Marks swing highs and lows only after N closed bars have confirmed them, so a drawn swing never moves or disappears.

Turtle-style Donchian breakouts on gold, followed with three exits at once: an ATR trailing stop, the Turtle exit channel and a fixed target. Backtested on XAUUSD H1 and H4 in 2025 and 2026, where all twelve combinations were profitable. Non-repainting, with buffers for an Expert Advisor.

Finds the weekend CME gap on gold and on 24/7 Bitcoin charts, keeps every unfilled gap on the chart until price returns to it, and shows how often gaps filled, how fast, how far price ran first, and what fading them would have made. Non-repainting, with buffers for an Expert Advisor.

MQL5 port of a Pine Script ATR trailing-stop indicator: nLoss = ATR-multiple, the stop ratchets under price in an uptrend and over price in a downtrend, and flips (with a buy/sell arrow) when price closes through it. Includes a Python reference port and a parity test that checks both agree with a literal, bar-by-bar transcription of the Pine semantics (na/nz/series history).

Time weighted average price of the running session, anchored at the cash open of Frankfurt, London, New York or Tokyo with automatic daylight saving. Every second counts the same, minutes without a tick carry the last price, and two bands show the time weighted standard deviation around the line.

Marks the Asian session range, signals when London or New York sweeps one side of it and reverses, and keeps a scorecard of how every past signal ended in R, spread included. Non-repainting, with buffers ready for an Expert Advisor.

Free risk-based position size calculator built specifically for Gold (XAUUSD). Enter your account balance, risk percentage, entry price and stop-loss price - the indicator calculates the exact lot size, risk amount, stop distance, risk/reward ratio and potential profit, and draws entry, stop and take-profit lines on the chart. Contract size is read automatically from the symbol specification, so it works on any gold symbol without manual setup.

Hull Moving Average indicator displaying four periods on a single chart, colour-coded by direction (green for rising, red for falling, grey for flat). Implemented with a ring buffer and incremental running-sum math, so memory and CPU use remain constant regardless of chart history length. Buffer layout is documented and stable, making the indicator suitable for use with iCustom() from EAs. Supports 2, 3, or 4 Hull lines depending on configuration.

Spread histogram in a sub-window with current/avg/max/min stats, cost per trade, and threshold alerts for scalpers.

Numbers every candle of the current trading day starting at the cash open of Frankfurt, London, New York or Tokyo.
