A candlestick chart packs four data points — open, high, low, close — into a single visual shape per period, communicating far more than a simple line chart's closing price alone.
What a Candle Actually Shows
The body spans the open and close price; a green (or white) body means the close was higher than the open, a red (or black) body means the reverse. The wicks (or shadows) extending above and below mark the high and low reached during that period. Specific patterns carry recognized meaning: a doji (open and close nearly equal, signaling indecision), a hammer (a small body with a long lower wick after a downtrend, often a reversal signal), and an engulfing pattern (a candle's body fully overtaking the prior candle's body, signaling a potential shift in control between buyers and sellers).
A nuance worth flagging: A single candlestick pattern in isolation is a weak signal — its reliability increases meaningfully when it appears at a pre-existing support or resistance level, aligning multiple independent signals rather than relying on the candle shape alone.
Someone New to Reading Candlestick Charts: Focus first on the basic body/wick mechanics before memorizing dozens of named patterns.
Someone Spotting a Reversal Pattern Mid-Trend: Check whether it aligns with a independently-identified support or resistance level for stronger confirmation.
Read Candlesticks the Way
- Learn the open/high/low/close mechanics before pattern names.
- Confirm any single pattern against support/resistance levels.
- Use candlesticks alongside volume for stronger confirmation.
