FVG Gap Detector

FVG Gap Detector

XAU Gap Detector — MQL5 Expert Advisor

Automated FVG (Fair Value Gap) trading for XAU with multi-timeframe detection, EMA filtering, money-management options, trailing/breakeven logic and clear visual confirmations — built for scalpers and swing traders who want a configurable, safety-first EA.

Multi-TF FVG detector for XAU with EMA trend filter, adaptive money management, trailing & breakeven — plug into MT5 and trade smarter.

This Expert Advisor scans multiple timeframes for Fair Value Gaps (FVGs) on XAU, applies optional EMA trend filtering and price-action confirmations, then places trades with configurable risk, fixed lots or money-management, stop loss, take profit, trailing stop and breakeven logic. It draws FVG rectangles and confirmation markers on the chart so you can visually validate signals. Time-of-day controls and Friday blocking reduce exposure during risky hours.

• Minimum gap thresholds per timeframe to avoid tiny/insignificant gaps.

• EMA filter (fast + slow) to align entries with the trend.

• Price-action confirmation option (require close above/below FVG).

• Flexible risk options: fixed lot or money-management by risk percentage.

• Standard protective functions: SL, TP, trailing stop (with minimum profit before trailing activates).

• Breakeven stop activation with buffer.

  These defaults prioritize controlled risk and avoid hyperactive micro-TF trading until you validate performance.

1. Backtest across each timeframe and over different market regimes (trending, ranging).

2. Use a demo account for a sustained period (minimum several weeks) before going live.

3. Start with low risk (0.5–1% per trade) and monitor slippage/spread sensitivity on XAU.

4. Check visual markers and logged trade rationale to confirm EA logic matches expectations.

5. Once satisfied, deploy to a small live account and scale gradually.

• Designed primarily for XAU (gold) instrument — check symbol naming in your broker (e.g., XAUUSD , XAUUSD+ ).

• Spread, slippage and broker execution speed materially affect results; test with your broker’s demo account.

• Trailing and breakeven depend on tick updates — low-liquidity sessions may behave differently.

• No news filter built in — consider using a separate economic calendar/news block if you want to avoid high-impact events.

• Past backtests are not guarantees of future returns. Always manage position sizing and diversification.

• Place the EA .mq5 and any accompanying .ex5 files into MQL5/Experts .

• Attach to an XAU chart at your desired timeframe (or a neutral timeframe if EA scans multiple TFs).

• Configure inputs from the EA properties dialog before starting.

• Monitor the journal and logs for any runtime messages.

• v1.0 — Initial release: Multi-TF FVG detection, EMA filter, money management, trailing & breakeven, visual markers.

• v1.1 — (future) Add news filter, improve FVG validity logic, performance optimizations.
