OHLC (Open, High, Low, Close) data is the foundation of technical analysis. Every candle on a chart represents these four values. Here's how to use them.
What Each Value Means
- Open — Price at the start of the period
- High — Highest price during the period
- Low — Lowest price during the period
- Close — Price at the end of the period
Common Candlestick Patterns
- Bullish engulfing — Green candle fully covers previous red → reversal up
- Bearish engulfing — Red candle fully covers previous green → reversal down
- Doji — Open ≈ Close → indecision, potential reversal
