Happy Kangaroo: Trend-following MT4 indicator for volatility-based entries and dynamic support resistance

This 2026 review of Happy Kangaroo presents a concise performance analysis based on backtests and live-demo tracking across major forex pairs. The indicator combines price action cues with Average True Range calculations to plot volatility bands that act as dynamic support and resistance. In our analysis Happy Kangaroo showed consistent directional bias during trending phases and the author Pui Yan Leung exposes adjustable ATR period and factor settings so traders can tune sensitivity for different instruments and timeframes. Happy Kangaroo is unique because it prioritizes volatility-confirmed entries rather than relying solely on moving average crossovers. The internal algorithm constructs ATR-based envelopes and flags a trend when price closes beyond the band combined with momentum confirmation. Signals are drawn as clear overlays on MT4 charts, and the implementation uses closed-bar calculations to prevent repainting and improve signal reliability during forward testing. The indicator performs best in medium-to-high volatility trending markets and will naturally reduce signal frequency during low-volatility congestion. Risk controls are built around ATR-based stop placement, optional fixed pip stops, and configurable position sizing tied to account risk percentage. Expect moderate trade frequency with emphasis on trade quality rather than quantity; in backtests on EURUSD 1H and 4H we observed typical trade durations between 12 and 48 hours and consistent responsiveness to breakout expansions.
