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.
What this EA does (user-facing summary)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.
Key features-
Multi-timeframe FVG detection: M1, M5, M15, M30, H1, H4, D1 (individually enabled/disabled).
-
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).
-
