A single candlestick contains four prices and a story about who won the period. Most beginners look at the colour and move on, which discards roughly three quarters of the available information. Learning to read one candle properly is the foundation everything else in technical analysis rests on.
The three chart types
Line charts connect closing prices. Clean and uncluttered, useful for seeing overall direction on long timeframes, but they discard the high, low and open entirely.
Bar charts show all four prices as a vertical line with small horizontal ticks for open and close. All the information is present, but it is harder to read quickly.
Candlestick charts show the same four prices with a coloured body between open and close. The visual encoding makes direction and conviction immediately obvious, which is why nearly all traders use them.
This lesson focuses on candlesticks. There is no meaningful advantage to bar charts beyond personal preference, and line charts are best reserved for stepping back to see structure without detail.
Anatomy of a candlestick
Every candle shows four prices for its period.
Open — first traded price of the period
High — highest price reached
Low — lowest price reached
Close — final traded price
The body spans open to close. The thin lines above and below are wicks (also called shadows), showing the extremes reached during the period.
A bullish candle closes above its open. A bearish candle closes below. Colours vary by platform — green and red are conventional, but the direction is what matters, not the colour scheme.
Reading what a candle tells you
Here is where most beginners stop too early. The body and wicks together describe a struggle and its outcome.
Body size — conviction
A long body means price moved decisively from open to close. One side controlled the period.
A short body means open and close finished close together. Neither side achieved much, regardless of what happened in between.
Wick length — rejection
This is the part that carries the most information.
A long upper wick means price rose during the period and then fell back before the close. Buyers pushed up, sellers pushed back harder. That level was rejected.
A long lower wick means the reverse — price fell, buyers stepped in, and the close recovered.
Long lower wick, small body, close near high:
Price fell significantly during the period,
buyers entered at the lows, and the period
closed near where it opened.
Sellers tried and failed at that level.
At a support level in an uptrend, that candle is meaningful. In the middle of a range, the same candle means very little.
Location determines significance. An identical candle can be a strong signal or pure noise depending on where it forms. This is why traders who memorise patterns without understanding levels perform worse than those who know three patterns and where they matter. We return to this repeatedly, because it is the concept beginners most often skip.
Timeframes and what a candle represents
The period each candle covers is set by your chart timeframe.
| Timeframe | Each candle | Typical use |
|---|---|---|
| M5 | 5 minutes | Scalping entries |
| M15 | 15 minutes | Intraday entries |
| H1 | 1 hour | Intraday direction |
| H4 | 4 hours | Swing entries |
| D1 | 1 day | Swing direction |
| W1 | 1 week | Long-term context |
Higher timeframe candles contain more information and produce more reliable signals, because more participants and more volume contributed to forming them.
A rejection candle on the daily chart represents a full day of participants failing to push through a level. The same shape on a 5-minute chart represents five minutes, possibly involving very little volume. They are not comparable signals despite looking identical.
The closing price matters most
Among the four prices, the close carries the most weight.
It is where the period settled after all the movement — the price participants were willing to hold at the end. Highs and lows can be reached briefly by a small order; the close reflects where the market actually finished.
This has a direct practical consequence: wait for candles to close before acting. A candle that looks like a strong rejection twenty minutes into a four-hour period can close as something entirely different.
Traders who act on forming candles regularly enter on signals that never actually appeared. This is one of the simplest habits to fix and one of the most frequently ignored.
Server time and the daily close
A detail specific to forex that affects every daily chart.
Because the market runs 24 hours, the daily candle boundary depends on where your broker sets it. Brokers on GMT+2 and GMT+3 produce different daily candles from the same underlying price data.
This means your daily candle may look different from another trader’s, and levels derived from daily highs and lows may differ. Most forex platforms use the New York close as the boundary, which has become the working convention.
Check your platform’s server time once and know which convention your charts follow.
Gaps
Forex has fewer gaps than stock markets because it trades continuously, but weekend gaps occur.
Price closes Friday at one level and opens Monday at another, reflecting weekend developments. Large gaps follow significant weekend news.
Gaps matter practically because a stop loss inside a gap does not fill at your level — it fills at the opening price, which may be considerably worse. This is the specific risk of holding positions over weekends, covered in the swing trading lesson.
Common mistakes reading candles
Reading colour only. A green candle with a long upper wick that closed near its low is not bullish, despite the colour. The wick and body position matter more.
Ignoring context. A pattern in isolation means little. The same formation at a well-tested level, in an established trend, after a pullback, is a different proposition.
Acting before the close. Covered above, and worth repeating because it is so common.
Reading low timeframes as equivalent. A 5-minute pattern carries a fraction of the weight of a daily one.
Over-reading single candles. One candle is one period. Structure — the sequence of candles — carries more information than any individual one.
A practical exercise
Rather than reading further immediately, this is worth doing.
Open a daily EUR/USD chart. Pick twenty consecutive candles. For each one, write down what happened during that day: did buyers or sellers control it, was there rejection at either extreme, and where did it close relative to the previous candle.
Twenty candles takes about fifteen minutes. Doing it for a week builds the reading habit faster than any amount of additional theory, because candle reading is recognition rather than knowledge.
What to do next
The next lesson covers the specific candlestick patterns worth knowing — a short list rather than the exhaustive catalogues most guides provide, and an explanation of why the short list is sufficient.
Frequently asked questions
What do candlestick wicks mean?
Wicks show the extremes price reached before closing elsewhere. A long upper wick means price rose and was pushed back — rejection at that level. A long lower wick means price fell and buyers recovered it. Wicks often carry more information than the body.
Which chart type is best for forex?
Candlestick charts, because they show all four prices with visual encoding that makes direction and conviction immediately readable. Bar charts contain the same data but are harder to read quickly; line charts discard three quarters of it.
Should I wait for a candle to close before entering?
Yes. A candle that looks like a strong signal partway through its period can close as something entirely different. Acting on forming candles means regularly entering on signals that never actually appeared.
Why is the closing price the most important?
Because it shows where the market settled after all the movement — the price participants were willing to hold. Highs and lows can be touched briefly by a small order, while the close reflects where the period genuinely finished.
Why does my daily candle differ from other charts?
Because forex has no universal daily close. Brokers set their own daily boundary, commonly GMT+2 or GMT+3, which produces different daily candles from identical price data. Most platforms use the New York close as a working convention.
What timeframe should a beginner use?
The 4-hour and daily charts. Higher timeframe candles form from more participation and produce more reliable signals. Lower timeframes generate far more patterns, most of which are noise.
