What you will learn
- How to translate a candle’s shape into a plain description of what trading did during the period.
- The common names for some shapes and short sequences: doji, hammer, shooting star, engulfing, and morning or evening star.
- Why the same shape can come from very different sessions, and where candle reading falls short.
Can a shape tell a story?
Before naming a candle, can you say in one sentence what price did during that period?
The previous lesson, candlestick anatomy, measured candles. This one asks what those measurements describe. The habit to build is translation: turn a shape into a sentence about trading activity, and only then attach a name, if a name helps at all.
For example, a candle with a long lower wick and a close near its high can be translated as: “During this period, prices traded well below the open, and by the end of the period they had come back up and finished near the top.” That sentence is accurate. Saying “buyers won” adds an interpretation the candle cannot prove, because a candle does not show who traded or why.
Why do names exist at all?
Is a name a discovery about markets, or a label people agreed on?
Candle names are shared vocabulary. They let two people refer to a shape quickly. Many are traditionally traced to Japanese rice-market charting and were later popularized in Western markets, though accounts of the exact origins and dates differ. A name is a label for geometry; it is not evidence of what happens next. Definitions also vary: one book’s “small body” is another’s “medium”, and platforms that detect shapes automatically use their own thresholds.
What is a doji?
If price traveled a long way but ended where it began, what does that describe?
A doji has an open and close that are equal or very close, so the body is a thin line. The wicks can be long, short or uneven.
Plain description: by the end of the period, the net change was close to zero. If the wicks are long, there was meaningful travel in both directions that was undone by the close. If they are short, the period was simply quiet.
Context changes the description. A doji after a long string of wide candles describes a pause in net movement. A doji in a market that has been drifting sideways describes more of the same.
Doji. Near-equal open/close describes net displacement, not measured indecision.
SINGLE CANDLES
Open and close nearly equal; little net displacement. Intent/indecision is not measured.

What are hammers and shooting stars?
Which side did price explore, and where did it finish?
Both shapes have a small body near one end of the range and one long wick.
- A hammer has a long lower wick and a small body near the top of the range. Description: price traded well below the open during the period and finished back near the high. The name is usually applied after a decline.
- A shooting star has a long upper wick and a small body near the bottom of the range. Description: price traded well above the open and finished back near the low. The name is usually applied after a rise.
Some traditions give the same shapes different names depending on where they appear in a move (hanging man, inverted hammer). The geometry is the same; only the label follows the context.
Hammer. A small body near the high and long lower wick after a decline is geometry, not proof of particular buyers recovering.
Read the diagram step by step
- CANDLESTICK PATTERNS
- After a decline: a small body near the top with a lower shadow at least twice the body.
- Small body near the high, long lower wick; after a preceding decline under this naming convention. Price traded lower and finished near the high.

Candlestick shapes diagram
Illustrative diagram constructed for teaching. Not real market data.
The diagram shows constructed examples of a doji, a hammer, a shooting star, an engulfing pair and a morning star, each with a one-line plain description instead of a forecast. It is constructed for teaching and is not real market data.
What is an engulfing pattern?
What does it mean when one period’s body covers the previous period’s body?
An engulfing sequence is two candles in which the second candle’s body spans the whole of the first candle’s body, and the two bodies point in opposite directions.
Description: the second period’s net move was larger than the first period’s and in the other direction. For example, a small close-below-open body followed by a larger close-above-open body that starts below the first body and ends above it.
Definitions differ on details: whether wicks count, whether the bodies must cross the exact open and close, and whether gaps are allowed. If your strict rule requires the second body to start strictly beyond the prior close, a pair whose next open equals that close fails that strict inequality. A definition allowing equality may classify the same pair differently. This is a threshold/session-convention issue; this lesson provides no measured frequency for how often strict engulfing occurs on any market or timeframe. That is a reminder that names were developed for particular charts and sessions.
Bullish Engulfing. The second oppositely directed body covers the first under the declared boundary rule; context is not an efficacy ranking.

What are morning and evening stars?
What does a three-step sequence of large, small, large describe?
A morning star is a three-candle sequence: a large close-below-open candle, then a small-bodied candle, then a large close-above-open candle that closes well into the first candle’s body. An evening star is the mirror image after a rise.
Description: a strong net move in one direction, a period of little net change, then a strong net move in the other direction. Whether that matters depends on everything around it.
How do traders read candlestick shapes in context?
What would you need to know besides the shape before saying anything about it?
A shape on its own is a small sample of one or a few periods. Questions that add context:
- Where is it? Near a level marked earlier (support and resistance), in the middle of a range, or far from any reference?
- How big is it compared with recent candles? A “long wick” in a quiet market may be ordinary in a busy one.
- What did the timeframe above show? A hammer on a short chart may be one wiggle inside a larger candle (timeframes).
- What happened in volume? Trading volume adds information the candle omits.
- Was there news? A scheduled release can produce shapes that reflect one burst of activity (economic events).
Try it on a chart
- On this daily chart, find a candle with a long lower wick and one with almost no body.
- Look at the candles before each one and describe the context in your own words.
Charts and quotes are TradingView's data, not ours, and may be delayed.
What are the limits of candlestick patterns?
If a shape were enough on its own, why would anyone need anything else?
- Hindsight is easy. Shapes that preceded big turns are memorable; the many identical shapes followed by nothing are forgotten.
- Definitions are loose. Without exact rules, two people can disagree on whether a shape is present, which makes casual claims about shapes hard to check.
- Settings change shapes. A different session or bar alignment can turn a hammer into an ordinary candle.
- Published claims vary. Any claim about how candle patterns behave depends on the market, period, definitions and costs used, so no single number describes them. Testing any idea honestly is the subject of plans, journaling and honest testing.
What this does not tell you about candlestick shapes
- Who traded, how much, or why.
- What the next candle will do.
- Whether a named shape means the same thing in every market or timeframe.
Method in Practice: a candle only counts at a planned level
Fictional example. John, Harbor Index futures, the prices, times, costs and results are all invented for teaching. This shows how a written plan can be built and tested. It is not a recommendation, and nothing here says how often this idea works.
Try it on a real chart. Look at the chart in this lesson, then test this idea yourself on past sessions with bar replay. Keep your own count, including the days with no trade.
The idea. A candle shows open, high, low and close. It doesn't show who traded or what comes next (this lesson). John uses one shape, a long lower wick with a close near the top, only at a level he marked before the open. The same shape anywhere else means nothing in his plan.
John's plan
- Setup
- prior day low 99.50, marked on the pre-session map
- Enter if
- a 30-minute candle trades below 99.50, has a lower wick at least half its range, and closes in its top third. Buy.
- Wrong if
- a 30-minute period closes below 99.30
- Manage
- take half at 100.10, the rest at 100.60 or by 14:30
- Risk
- $150 maximum, costs included
Three outcomes
-
Worked: the shape at the level, then up → +$100
-
Failed: the same shape at the level, then through it → −$124, inside the limit
-
No trade: the same shape, but at 100.40, nowhere near the level → $0
Show the full replays
| Item | Plan |
|---|---|
| Context | Prior day low 99.50 |
| Entry condition | A 30-minute candle with low below 99.50, lower wick (lower of open and close, minus low) at least half its range, close at or above high − one third of the range. Buy 2 at market after that close |
| Wrong if | A 30-minute period closes below 99.30. Exit at market after that close |
| Management | Take profit on half at 100.10 (limit) and move the exit for the rest to the entry price (stop). Rest at 100.60 (limit). Time limit 14:30 CT |
| Risk cap and size | $150. Exiting just under 99.30 is planned to cost about $65 per contract, so 2 contracts |
| Not trading if | Scheduled major release within the hour, or no setup by 12:00 CT |
Replay A: worked
| Time (CT) | What happened | John |
|---|---|---|
| 09:30–10:00 | Open 99.62, high 99.80, low 99.35, close 99.75. Range 0.45, lower wick 0.27, close in the top third | Condition met: buys 2 at market, filled 99.80 |
| 10:00–11:20 | Trades 100.10 at 11:20 | Sells 1 at 100.10 (limit). Exit for the other moves to 99.80 |
| 11:20–13:30 | Never back to 99.80, trades 100.60 at 13:30 | Sells the last 1 at 100.60 (limit) |
Result after costs: +0.30 point = +$30, +0.80 point = +$80, commissions −$10. Net +$100.
Replay B: failed
| Time (CT) | What happened | John |
|---|---|---|
| 10:00–10:30 | Open 99.60, high 99.76, low 99.38, close 99.72. Range 0.38, lower wick 0.22, close in the top third | Buys 2 at market, filled 99.77 |
| 10:30–11:00 | Falls, closes 99.25 | Wrong-if met: sells 2 at market, filled 99.20 |
Result after costs: 2 × −0.57 point = −$114, commissions −$10. Net −$124. Journal: "Textbook shape at my level, and it failed within one period. The shape wasn't a promise."
Replay C: no trade
| Time (CT) | What happened | John |
|---|---|---|
| 10:30–11:00 | The same shape at 100.40 | Not at the level: not a condition |
| 11:00–12:00 | No candle at 99.50 | No setup. 12:00 cutoff |
Result: $0.
Test it yourself
- Write the shape as numbers (wick size, close position), not as a name.
- Replay every candle at your level that meets the numbers, including the ones that failed.
- Compare with the same shape away from any level. If they behave the same, the level adds nothing.
Where it breaks
- A candle shows prices, not participants.
- Shape names mean different things in different markets and timeframes.
- The same shape can come right before a drop (the failed replay).
Calculators: position sizerisk/rewardexpectancy
Reflection question: Could someone else check, from your written rule alone, whether a candle qualifies?
Check yourself
Reflect on these; there is no score.
- Describe a shooting star in one plain sentence without using the words “buyers” or “sellers”. Hint: where price went and where it finished.
- Why can an equal prior-close/next-open pair fail a strict-gap engulfing rule but satisfy an equality-allowed variant? Hint: where each candle opens.
- Pick a doji on any chart. List three pieces of context you would check before describing it. Hint: location, relative size, other timeframes.
- Why can memorable examples make a shape seem more meaningful than it is? Hint: what gets forgotten.
- Does a doji prove traders were indecisive, or a hammer prove particular buyers defeated sellers?
Reflect on your own process
- Does your written plan define each candle shape you name with exact thresholds, such as how small a doji body must be?
- When you journal a named candle, do you first write a plain sentence about where price went and finished?
- How would you record the shapes that looked similar but were followed by nothing, so memorable cases do not skew your review?
- Could someone else check, from your written rule alone, whether a candle qualifies?
