HighLow Alarm: Visualize previous-day highs and lows for MT5 trading

This HighLow Alarm review in 2026 examines indicator behavior, measured performance, and independent analysis of signal quality across multiple symbols and timeframes. The detailed performance analysis highlights how consistently plotted daily highs and lows provide repeatable reference points, and the indicator is tested on forex majors, indices, and commodities to assess robustness. HighLow Alarm uses the daily timeframe as a single source of truth and maps the previous session's extreme values onto intraday charts to reveal where price frequently stalls or accelerates. What makes HighLow Alarm unique is its strict, single-purpose design: it does not attempt to predict direction but instead visualizes high-probability decision zones that many professional traders respect. The algorithm reads completed D1 bars and calculates exact high and low values, then displays two persistent horizontal lines and optional alerts. It handles range-bound mornings and trending breakouts well when combined with momentum confirmation. Risk management is external to the indicator but the recommended workflow pairs HighLow Alarm signals with fixed stop sizes, ATR-based exits, and position sizing rules. Expected performance characteristics on tested samples show moderate win rates with favorable risk-reward when users apply disciplined filters and trade sizing. For clarity, the indicator includes adjustable alert settings and straightforward visual customization, making HighLow Alarm a practical tool on MT5 for traders focused on data-driven setups.
