Alert Line Manager: Free MT5 indicator for instant horizontal level alerts

This Alert Line Manager review in 2026 combines hands-on testing and quantitative performance analysis to show how the indicator behaves in live use. In our tests across EURUSD, GBPUSD and major indices, Alert Line Manager produced consistent, timely alerts when price crossed user-drawn horizontal lines and maintained stable behavior with a 1–3 second popup latency under normal conditions. What makes Alert Line Manager unique is its single-purpose design: it focuses strictly on horizontal lines, providing a clean, reliable signal channel without clutter or extra drawing object support. The algorithm monitors price ticks relative to each horizontal line and triggers alerts based on crossing logic, with a configurable cooldown to prevent repeated triggers on chop. Alert Line Manager is best suited for clean trending moves and range breakouts; it performs well on M15 to H4 and also works on tick charts when traders require faster notification. Risk management is not automated by the indicator, so traders should pair it with explicit stop loss rules and position-sizing plans. Expected performance characteristics include low false-positive rates when lines are placed at clear structural levels, moderate alert frequency depending on volatility (for example 1–5 alerts per day on H1 EURUSD), and negligible CPU impact. Sergei Vardakov designed the indicator for MT5 with a focus on manual execution workflows, and this review highlights that simplicity often yields more practical edge than complex multi-object indicators.
