MQL5 Source Codes of Technical Indicators for MetaTrader 5

When I first started scalping, I had a problem: during periods of high volatility, it sometimes took too long to calculate exactly 1%, and I’d end up setting an incorrect stop-loss or using a position size that was too low or too high. But with this calculator, I can do it much faster—I just have to drag a line to the stop-loss zone, and it automatically calculates the position size I should use for my 1%. I hope you find it very useful!

Auto Fibonacci retracement for Gold (XAUUSD), forex and any symbol: draws the levels on the last completed swing leg by itself, with the 61.8 in its own colour, prices on each level and an optional alert. Open source code.

An all-in-one Smart Money Concepts (SMC) indicator that automatically identifies Swing & Internal Market Structure (BOS/CHoCH), Order Blocks, Premium/Discount zones, and Equal Highs/Lows. It features a real-time multi-timeframe bias dashboard to help traders make informed decisions.

On a linear MT5 chart, a trend that grows or falls by a steady percentage is a curve, and a straight channel misses it. This indicator draws the real exponential curve, fitted on closed bars to the cleanest of 19 look-back windows, with deviation zones, a projection ahead and a card with the fit, the trend pace and the price position.

Real-time tick spread monitor that plots Maximum and Average spread curves per bar with points/pips display and local CSV persistence.

Countdown to the next high-impact news from the MT5 economic calendar, with a red NEWS WINDOW warning for prop-firm news rules. Display and alerts only - it never trades.

Drag the MetaTrader 5 chart freely in any direction and stretch the price and time scales with the mouse, the way TradingView does it. One click on ON/OFF returns the normal chart. A small indicator that draws nothing, never trades and works next to any Expert Advisor.

Plots the range of the Asian session and marks breakouts during the London session with arrows, stop and target levels, and alerts

Draws the daily opening range and its breakout levels, with a dashboard showing how the range resolved over your lookback: broken up, down, both ways or not at all, and how often a breakout hit its target before the opposite side.

Prop Firm Guard Panel is an on-chart panel for prop firm challenges and funded accounts. It shows in real time the daily loss used and the room left, the max loss room and equity floor, and the progress toward the profit target. The start-of-day balance is rebuilt from today's closed deals, so the values stay correct after a restart. Colors change from green to orange to red as limits get closer, with optional popup and push alerts. Auto, dark or light theme. Display only: it never opens, modifies or closes trades.

Trending up, trending down or ranging: a verdict for every bar, and how long it has held. Each stretch of one regime is boxed on the price chart, ADX columns below show how strong it is, and a one-line panel gives the regime, its age and the ADX. Values for Expert Advisors and an alert on closed bars.

Non-repainting fair value gaps on closed bars, with zone states (active, touched, mitigated) and iCustom buffers for EAs.

Real-time daily drawdown buffer monitor and exact breach price line indicator for prop firm accounts. Features 00:00 server-time deal history reconstruction (including entry commissions), 00:00 HWM snapshot locking, two-stage OrderCalcProfit cross-rate calibration, and iCustom() data buffers for Expert Advisors.

Shows the current spread next to its recent average and maximum and compares it with ATR, so you can see at a glance when trading costs are too high relative to the symbol's normal movement.

On-chart panel that calculates the lot size for a given risk (% of balance, % of equity or fixed money) and stop-loss distance, using the broker's tick size and tick value. Works on forex, metals, indices and crypto.

Draws the previous day, previous week and previous month high and low, plus automatic round-number levels around the current price. Every level carries a label with how many times price touched it and how many times a bar swept it (pierced the level and closed back on the original side). Counts use closed bars only, so they do not repaint. Optional alerts (popup, push, email, sound) for sweeps and new touches. Touch tolerance is a fraction of ATR or a fixed number of points. The 6 previous-period levels and their touch counts are exposed in 12 indicator buffers for use from an Expert Advisor with iCustom(). Works on any timeframe up to H4. Read-only: it never opens, modifies or closes a trade. No DLLs, no web requests.

Draws the opening range of a configurable session (start time and length in minutes, with a server time zone adjustment), the 1R and 2R levels above and below the box, and the session VWAP (tick volume, or real volume when the broker provides it). A small panel counts, over the last N finished sessions, how many broke the range up only, down only, on both sides, or not at all, and how often price reached 1R and 2R after the first break. The statistics are historical counts: they describe the past and do not predict anything. Only closed bars are used, so nothing repaints; optional popup, push and sound alerts fire once per direction per session when a closed bar closes outside the box. Eight buffers (range, targets, VWAP, break state) can be read from an Expert Advisor with iCustom(). Works on M1 to M30, recalculates only new bars and deletes its chart objects when removed. Read-only: it never trades. No DLLs, no web requests.

Draws the high and low of the Asia, London and New York sessions as boxes or lines extended to the end of the day, with configurable session hours and a server time zone adjustment. Optional previous day and previous week high/low. When a CLOSED bar breaks the high or low of a session that has already finished, it can raise a popup alert, a push notification and/or a sound, once per level per day. Alerts are evaluated on closed bars only, so they do not repaint. The 10 levels are exposed in indicator buffers, so an Expert Advisor can read them with iCustom(). It recalculates only new bars, works on any timeframe up to H1, and deletes all its chart objects when removed. Read-only: it never opens, modifies or closes a trade. No DLLs, no web requests.

Marks bullish and bearish engulfing, bullish and bearish pin bar and inside bar patterns with arrows, using closed bars only, so nothing repaints. The definitions (wick and body proportions, minimum bar size in ATR) are inputs, with an optional EMA trend filter. For each pattern a small panel shows a rolling historical statistic: the share of the last N resolved cases where price moved X ATR in the pattern direction before moving Y ATR against it, together with the number of cases. X, Y, N and the waiting time are inputs. The numbers describe what happened on your chart history; they do not predict the next trade. Optional alerts on closed bars (popup, push, sound). 20 buffers (signal, hit rate and sample size per pattern) can be read with iCustom(). Uses prev_calculated, deletes its chart objects when removed. Read-only: it never trades. No DLLs, no web requests.

Draws the high and low of a chosen time window and alerts on the first break on each side. The levels are also available through iCustom.

Auto Fibo Extended is a MetaTrader 5 indicator designed to automatically identify significant swing highs and swing lows and draw Fibonacci Retracement and Extension levels directly on the chart.

A regime-classification oscillator that measures how far, and how persistently, price deviates from a rolling volume-weighted VWAP in standard-deviation units, separating trending conditions from ranging ones.

A small include class that stops indicator alerts from firing on every tick. One alert per event and bar, silent about history on start, popup, push, email or sound, and an optional log of every decision. Comes with a working range break indicator as an example

On-chart table that shows how much each Expert Advisor (magic number) made or lost today, this week and this month, with closed and floating profit, number of closed trades today and the intraday drawdown. Manual trades (magic 0) get their own row and a TOTAL row sums the whole account. MT5 only shows one account-wide balance, so when several EAs trade together you cannot see which one is carrying the day or bleeding. Give your magic numbers readable names ("1001=Breakout;1002=Grid"), choose the corner and theme, and decide whether floating profit is included. Read-only: it never opens, modifies or closes a trade, and it works in the Strategy Tester too (it reads the tester's own deals), so you can try it before using it on a demo or live account. No DLLs, no web requests.

Splits all open positions into currencies and shows the net exposure per currency in account money, the effective leverage of the account and how much a 1% currency move would change your equity.

Draws Asia, London and New York session high/low boxes with each session's range in pips or price, plus a live spread and open-sessions panel.

Draws Asia, London and New York session boxes on the chart with each session's high and low.

Drag the stop-loss line and read the lot size that risks exactly your money or percent. The CRiskSizer class does the same in an EA: lot rounded down, minimum lot never forced, max lot, volume limit, stop level and margin checked.

CBrokerTime converts server time, UTC, New York, London, Sydney and Tokyo with the real summer time of every year and finds your broker's clock from the history (also in the tester). The indicator draws session lines and a clock panel.

A clean Heikin Ashi indicator that draws on the main chart window. It also adds one horizontal line at the average price, (Open + High + Low + Close) / 4, of the last closed candle of a chosen timeframe. By default this is H1, and the line uses the normal candles, not Heikin Ashi.

Market structure indicator for Gold (XAUUSD), EURUSD and any symbol: swing highs and lows with HH HL LH LL labels, BOS and CHoCH drawn on closed candles, alerts and 4 buffers for EAs. Open source code.

Range boxes that are drawn when market trend strength weakens

Highlights the Asia, London and New York sessions and the London/New York overlap using real local time and daylight saving rules, so the session boxes are correct on any broker.
