Z-Candle Range 4U highlights these extreme candles directly on your chart, providing a clear view of where volatility is expanding or contracting.
You simply select the number of bars to analyze (n), and the indicator automatically identifies:
- The candle with the largest High-Low range (Max Range) → signals strong volatility
- The candle with the smallest High-Low range (Min Range) → signals price compression
- The candle with the longest Open-Close body (Max Body) → indicates the strongest directional push
- The candle with the shortest Open-Close body (Min Body) → indicates hesitation or market balance
📌 Ideal for:
- Detecting volatility shifts before breakouts or reversals
- Spotting strong momentum signals, including breakout or impulse bars
- Identifying accumulation phases and low-volatility periods, useful for breakout strategies
- Recognizing market pauses and decision-making zones, often preceding major moves
- Analyzing momentum structure and energy of each price swing
- Integrating into visual strategies for easy interpretation of market behavior
📌Key use cases:
- Detect volatility shifts before breakouts or reversals:
When candle ranges (High-Low) expand unusually after a compression phase, it often signals returning volatility. Z-Candle Range 4U makes this expansion clear, helping you prepare for upcoming breakouts or reversals. - Spot strong momentum candles (breakouts or impulse bars):
When a candle has the longest body (Max Body) in the cycle, it often reflects a powerful push from either buyers or sellers. These are impulse bars – where momentum bursts – signaling the start of a strong price swing or a high-probability breakout. - Detect accumulation phases and low-volatility periods:
When the indicator identifies candles with the smallest ranges, it indicates that volatility is contracting, and the market is storing energy. This “calm before the storm” phase is highly valuable for preparing and timing breakout setups. - Recognize market pauses and indecision zones:
Small-bodied candles with relatively wide ranges reflect hesitation and struggle between buyers and sellers. The indicator highlights these zones, which often precede significant moves. - Analyze momentum structure and energy of each swing:
Comparing candle sizes allows you to measure the strength of each price wave. Shrinking candles indicate weakening momentum, while gradually expanding candles suggest trend consolidation. - Integrate into visual strategies for easy market reading:
Z-Candle Range 4U highlights extreme candles directly on your chart, allowing traders to interpret price behavior visually. No complex calculations are needed to sense volatility, momentum, and structural changes accurately.
Additionally, the indicator includes alerts to notify you when extreme candles appear, even when you’re away from the chart.
