Candlestick charts are the universal language of price action. Every candle tells a story about the battle between buyers and sellers during a specific time period. Reading that story fluently — not just recognizing pattern names, but understanding what the price actually did and why it matters — is what separates traders who see the chart from traders who read it.
The Anatomy of a Candlestick
Every candlestick contains four data points:
- Open — The price at which the period began
- Close — The price at which the period ended
- High — The highest price reached during the period
- Low — The lowest price reached during the period
The body of the candle connects the open and close. If close > open, the candle is bullish (green/white). If close < open, the candle is bearish (red/black).
The wicks (shadows) extend from the body to the high and low. They tell you how far price traveled beyond the open-close range before being pushed back.
A wide body with small wicks means one side dominated decisively. Long wicks with a small body mean price probed in both directions but neither side won — indecision.
The Most Important Candlestick Patterns
1. The Hammer and Shooting Star (Pin Bars)
A hammer has a small body near the top of the candle range and a long lower wick — at least 2× the body length. Price sold off sharply during the session but buyers pushed it back up near the open. At support levels after a downtrend, this is one of the clearest signs of demand rejection.
A shooting star is the inverse: small body near the bottom of the range with a long upper wick. Sellers rejected the move higher and pushed price back to the open. At resistance after an uptrend, it signals supply absorption.
The rule: The longer the wick relative to the body, the more forceful the rejection.
2. Bullish and Bearish Engulfing
A bullish engulfing is a two-candle pattern: a bearish candle followed by a bullish candle whose body completely covers the prior candle's body. It shows buyers overwhelmed sellers entirely — all the selling from the prior session was absorbed and reversed.
For SPY at a $540 support level: if yesterday closed red at $541 after opening at $545, and today opens at $540 and closes at $547 — that's a bullish engulfing at support. The buying pressure is undeniable.
A bearish engulfing is the reverse: a bullish candle followed by a larger bearish candle that swallows the prior body. Sellers dominated every attempt at buying.
3. The Doji: Indecision Made Visible
A doji forms when open and close are nearly identical, leaving a very small body with wicks extending in both directions. Neither buyers nor sellers won the session. The market is at an inflection point.
Context is everything with a doji. A doji after a strong uptrend at resistance is significant — it suggests the bullish momentum is stalling. A doji in the middle of a messy sideways range tells you nothing useful.
There are several doji variants:
- Dragonfly doji — long lower wick, small upper wick, open = close near the high. Bullish reversal potential at support.
- Gravestone doji — long upper wick, small lower wick, open = close near the low. Bearish reversal potential at resistance.
- Long-legged doji — long wicks in both directions. Maximum indecision — a big move is often coming, direction unclear.
4. The Inside Bar: Compression Before a Move
An inside bar occurs when a candle's high and low are completely within the prior candle's range. Price is contracting, compressing energy. An inside bar after a strong move often signals a brief pause before continuation. An inside bar at a key level can signal the beginning of a breakout.
The setup: when the inside bar finally breaks above its high (bullish) or below its low (bearish), that's the trigger.
5. Marubozu: Pure Conviction
A marubozu is a candle with a full body and almost no wicks — open = low, close = high (bullish) or open = high, close = low (bearish). It represents total one-sided control. One group completely dominated the session with no meaningful pushback. These candles are the clearest expression of directional momentum in the candlestick toolkit.
The One Rule That Changes Everything: Context Over Pattern
Here's what most candlestick guides won't tell you: the pattern is the least important part. Context is everything.
The exact same hammer pattern means completely different things in different situations:
| Situation | Interpretation |
|---|---|
| Hammer at key support after downtrend | High-probability reversal signal |
| Hammer at 50-day MA in a strong uptrend | Pullback ending, continuation likely |
| Hammer in the middle of a choppy range | Meaningless noise |
| Hammer at resistance after long uptrend | Potential fakeout trap |
Before trading any candlestick pattern, ask:
- Where is it? (At a key level, or random price?)
- What direction was price moving before it? (With or against the trend?)
- What does volume say? (High volume on a reversal candle = conviction)
- What does the higher timeframe show? (Daily support holds more weight than 5-minute)
Volume Confirmation: The Pattern Doesn't Lie When Volume Speaks
A reversal candle with high volume carries far more weight than the same pattern on low volume. High volume at a support hammer means institutional buyers showed up. Low volume means retail traders are reacting to a pattern while big money is absent — less reliable.
Watch for volume that is noticeably above average (1.5–3× the 20-period average) on reversal candles. That's your confirmation that something meaningful is happening.
Multiple Timeframe Alignment: The Final Filter
A bullish hammer on the 15-minute chart at a 15-minute support level is interesting. The same hammer on the daily chart at a weekly support level while the weekly trend is up is a significantly higher-probability setup.
Always confirm: what does the daily chart say? What does the weekly show? If the higher timeframe structure aligns with your pattern, the probability of success increases substantially. If higher timeframes are bearish while your lower-timeframe pattern is bullish, proceed with extreme caution.
How Lenzi Reads Candlesticks in Context
When you share a chart with Lenzi, it doesn't just list patterns — it reads them in structural context. If there's a hammer at the 50-day MA while the daily uptrend is intact, Lenzi tells you the pattern has meaning and why. If there's a bullish engulfing in the middle of a bearish distribution range on the weekly, Lenzi flags it as low-reliability. The pattern identification comes second to the structural read.
