Captures the upper price extreme of the period, exposing the maximum valuation the market momentarily accepted.
High is the highest traded price during the period. It marks the upper boundary of the price range.
The high price is the maximum price at which a security traded during a specific period—whether a single day, week, month, or year. This represents the peak of buying pressure during that timeframe, the highest price any buyer was willing to pay and any seller was willing to accept. The daily high is a key component of candlestick charts and technical analysis.
Why the high price matters:
- Resistance identification: Highs often mark price levels where selling pressure emerged
- Volatility measurement: High-low range shows intraday price movement
- Breakout analysis: Breaking above previous highs signals potential momentum
- Risk assessment: Distance from high to close may indicate rejection
Technical analysis applications:
- 52-week high: Breaking new highs often indicates strong momentum
- Resistance levels: Previous highs become future resistance zones
- Candlestick patterns: Upper shadows (high above close) suggest selling pressure
- Average True Range: Uses high-low-close for volatility calculation
Interpreting the high relative to other prices:
- High near close: Bullish; buyers maintained control into close
- High far above close: Bearish reversal signal; buyers lost control
- High equals open: Selling pressure from the start (in declining day)
- Narrow high-low range: Low volatility; consolidation or indecision
Key high price levels:
- All-time high: Highest price ever traded
- 52-week high: Highest price in past year
- Recent swing high: Local peak in price action
Trading considerations:
- New high breakouts: Often trigger momentum buying
- Failed breakouts: Price reaching high but closing lower may signal weakness
- High-volume highs: More significant than low-volume highs
The high price defines the upper boundary of price action for a period. Combined with the low, it defines the trading range and helps identify support, resistance, and volatility patterns.
