A candle contains exactly four numbers: the price at the start of the period, the highest price traded, the lowest price traded, and the price at the end. Everything else on a candlestick chart is a drawing convention. The rectangle spans open to close, the thin lines above and below reach to the high and the low, and the colour tells you whether the close finished above or below the open.
That is the whole format, and it has survived since Japanese rice merchants used it centuries ago because it packs a period's argument into one glance. A bar chart holds the same four numbers. A candle just makes the relationship between them visible without reading anything.
Body and wick record different things
The body is the settled part. It shows where the period opened and where it finished, which is the range over which one side actually held ground. A long body means the move ran in one direction and stayed there. A tiny body means the period ended roughly where it started, whatever happened in between.
The wicks are the rejected part. An upper wick marks price that buyers reached and could not hold; a lower wick marks the same for sellers. A candle with a long lower wick and a small body near the top is telling you that price was pushed down during the period and bought back before the close. On its own that is a piece of trivia. At a level that has already turned price twice before, it is the most useful single bar on the chart.
| Shape | What it looks like | What it records |
|---|---|---|
| Long body, small wicks | Solid block | One side controlled the whole period and closed near the extreme |
| Doji | Almost no body | Open and close met, so the period settled nothing |
| Long lower wick | Body near the top | Lower prices were reached and rejected before the close |
| Long upper wick | Body near the bottom | Higher prices were reached and rejected before the close |
| Engulfing | Body covering the previous body | The period reversed and exceeded the whole of the prior one |
| Inside bar | Range inside the previous range | Neither side extended the prior period's boundaries |
The timeframe writes the story
The same market produces completely different candles depending on how you slice the clock. A daily candle on gold might close as a clean bullish body while the five minute chart inside it contains four reversals, two of which would have stopped you out. Neither picture is wrong. They answer different questions.
This is why the sequencing matters more than the pattern vocabulary. Decide direction and levels on a higher timeframe, then use a lower one to time entry, which is the workflow described in chart timeframes. Reading candles exclusively on a one minute chart produces a shape every few seconds and no way to tell which of them mean anything.
Candle boundaries depend on the broker's server time. A daily candle that closes at 00:00 server time is a different candle from one that closes at 22:00 UTC, and patterns visible on one chart can disappear on another. If you trade daily closes, know which clock your platform uses.
Patterns are triggers, location is the signal
Named patterns get more attention than they deserve. Hammers, engulfing bars, morning stars and the rest describe recognisable shapes, and each of them occurs constantly. Search a year of EURUSD daily data for any of them and you will find dozens, most followed by nothing in particular.
What changes the odds is where the shape appears. A rejection candle at a tested level is a different event from the identical candle in the middle of a range, because the first one is the market failing at a price that already mattered and the second is ordinary noise wearing the same costume. The habit worth building is to mark your levels first, using the method in support and resistance, and only then look at what the candles are doing when price arrives there.
The second filter is participation. A wide range candle formed on very thin activity in the Asian session says less than the same shape during the London open, when far more of the market is present. Platforms that display tick volume give you a rough proxy for that, with the caveat that in over the counter forex it counts price updates rather than contracts traded.
Reading without naming
The most useful habit is to describe what you see in plain words before reaching for a pattern name. Three candles with progressively smaller bodies after a strong move: momentum is fading. A long body that closes back inside a previous range after breaking out of it: the breakout failed and anyone who bought it is now offside. A run of candles with long upper wicks at the same price: something is repeatedly selling there.
None of those descriptions needs a Japanese name to be actionable, and describing them yourself forces you to notice the sequence rather than pattern-matching a single bar. That is also the discipline underneath price action as a method rather than a label.
One honest caveat to finish on. Candles are a record of what already happened, and reading them well improves your judgement about probabilities, not your certainty about outcomes. Leveraged trading carries a high risk of loss, and no candle formation changes the arithmetic of position size and stop placement.
"I have never once entered a trade because of a candle shape. I have entered plenty because price reached a level I marked days earlier and the candle showed me it was being rejected there."

Key Takeaways
- Every candle holds four prices: open, high, low and close, drawn as a body and two wicks.
- Bodies show what was held; wicks show prices that were reached and given back.
- The same market tells different stories per timeframe, so set levels high and time entries low.
- A pattern only carries weight at a level that already mattered; elsewhere it is common noise.
Frequently Asked Questions
What do the wicks on a candlestick mean?
A wick marks price that was reached during the period but not held at the close. A long upper wick means buyers pushed price up and sellers pushed it back before the candle finished. It records rejection of a level, which is why long wicks at the edges of a range attract more attention than long wicks in the middle of one.
Are candlestick patterns reliable on their own?
No. The same shape appears hundreds of times on any chart and most occurrences lead nowhere. What changes the odds is location: a rejection candle at a level that has already turned price twice carries information, while the identical candle in the middle of a range is noise. Treat a pattern as a trigger inside a plan, never as a signal by itself.
Which timeframe should I read candles on?
Use a higher timeframe such as daily or four hour to decide where the meaningful levels are, then drop to a lower one for the entry. Reading candles only on a one minute chart produces dozens of shapes an hour with no context, which is the most common reason beginners see patterns everywhere and act on all of them.
