How to read candlestick charts (and what patterns can and cannot tell you)

A candlestick chart shows price movement as a series of candles, each one covering a fixed period such as one hour or one day. Each candle displays four prices: the open, the high, the low and the close. The thick part, the body, runs between the open and the close and is coloured to show whether price rose or fell; the thin lines above and below, the wicks, show the highest and lowest prices traded. Reading candles well means reading those four prices in the context of what came before, rather than memorising pattern names.

This guide explains how a candle is built, how timeframes change what you see, the handful of patterns worth knowing, and the limits of pattern reading, including a worked example.

Where candlesticks come from

Candlestick charts originated in Japan, where they were used to chart rice prices; their early development is traditionally attributed to the eighteenth-century rice trader Munehisa Homma. They were little known in Western markets until the late 1980s and early 1990s, when Steve Nison's writing popularised them. Today they are the default chart type on almost every trading platform, including MetaTrader, cTrader and TradingView. Our guides to MetaTrader 4 vs MetaTrader 5 and cTrader and TradingView cover the platforms themselves.

Anatomy of a candle

Every candle is built from four prices for its period.

• Open: the first price of the period.
• High: the highest price traded during the period.
• Low: the lowest price traded during the period.
• Close: the last price of the period.

These are drawn as follows.

• The body is the rectangle between the open and the close.
• The upper wick (also called the shadow) runs from the top of the body to the high.
• The lower wick runs from the bottom of the body to the low.
• The colour shows direction. A bullish candle closed higher than it opened; a bearish candle closed lower. Traditionally bullish candles are white or hollow and bearish ones black or filled. Most platforms now default to green for up and red for down, and you can change the colours to anything you like. Always check your platform's settings rather than assuming.

Worked example: reading one candle

Illustrative numbers. A one-hour EUR/USD candle has these values:

• Open: 1.0850
• High: 1.0878
• Low: 1.0842
• Close: 1.0871

Price closed above where it opened, so it is a bullish candle. The body runs from 1.0850 to 1.0871, a 21-pip body. The upper wick runs from 1.0871 to 1.0878, 7 pips. The lower wick runs from 1.0850 down to 1.0842, 8 pips. The total range, high minus low, is 36 pips. If pip arithmetic is new to you, see what is a pip.

What does it tell you? In that hour, sellers briefly pushed price 8 pips below the open, buyers then took it up to 1.0878, and it settled just below the high. Buyers controlled most of the hour, with a little selling at the top. That is all a single candle can say. It does not tell you who will control the next hour.

What bodies and wicks suggest

• A long body with short wicks means price moved decisively in one direction and closed near the extreme. One side was in control for the whole period.
• A small body with long wicks means price travelled a long way in both directions and ended near where it started. Neither side won; the period was indecisive.
• A long upper wick means price traded higher but was pushed back down before the close. Some traders read this as rejection of higher prices.
• A long lower wick means price traded lower but was pushed back up. The mirror image.

These are descriptions of what happened. They become useful only when you combine them with where the candle formed and what the surrounding market was doing.

Candles and the bid price

One technical detail catches many beginners. On most forex platforms, candles are built from the bid price, the price at which you can sell. You buy at the ask, which is higher by the spread. So when a candle's low touches your buy limit price, your order may not have filled, because the ask was still a little higher. The same applies to stop-losses on short positions, which trigger on the ask. Our guides to reading a forex quote and spreads and commissions explain the gap.

Timeframes: the same market, different stories

The period each candle covers is the timeframe. Common choices are one minute (M1), five minutes (M5), fifteen minutes (M15), one hour (H1), four hours (H4), daily (D1) and weekly (W1).

A single daily candle contains 24 one-hour candles. A daily candle that looks like a calm, small-bodied day might hide a sharp drop and full recovery inside it. A strong uptrend on the hourly chart might be a small bounce inside a downtrend on the daily chart. Neither view is wrong. They answer different questions.

Practical points:

• Use a higher timeframe for context and a lower one for detail. Many traders read the daily chart to judge the broader direction and key levels, then look at the hourly or four-hour chart to plan entries.
• Lower timeframes have more noise. The shorter the period, the more random the candles look, and the more the spread matters relative to the size of each move.
• Know when a daily candle closes. In forex, most brokers close the daily candle at 5pm New York time, which aligns with the daily rollover. A broker using a different server time may show an extra small candle for the Sunday open, which slightly changes daily patterns. Our guide to forex market hours and sessions explains why 5pm New York is the convention.
• Do not judge a candle before it closes. A candle that looks like a strong bullish bar halfway through the hour can finish as something entirely different. Pattern traders wait for the close.

Single-candle patterns worth knowing

There are dozens of named patterns. A few are worth recognising because they come up constantly and their logic is clear.

Doji

A doji has an open and close at or very near the same price, so the body is a thin line. It shows a period in which price moved but ended where it started. In isolation it says very little. After a long run in one direction, it can indicate that momentum is fading, but plenty of trends continue straight through dojis.

Hammer and hanging man

Both have a small body near the top of the candle and a long lower wick, typically at least twice the length of the body, with little or no upper wick. The name depends on where it appears. After a decline, it is called a hammer, and some traders read it as a sign that selling was rejected. After an advance, the same shape is called a hanging man, and is read as a possible warning. The fact that one shape gets two names and two meanings depending on context tells you most of what you need to know about candlestick patterns.

Shooting star and inverted hammer

The mirror image: a small body near the bottom of the candle and a long upper wick. After an advance, it is a shooting star, read as rejection of higher prices. After a decline, it is an inverted hammer.

Marubozu

A candle with a full body and little or no wick at either end. Price opened at one extreme and closed at the other. It shows strong one-way pressure for that period.

Multi-candle patterns

Engulfing patterns

A bullish engulfing pattern is a bearish candle followed by a bullish candle whose body completely covers the previous body. A bearish engulfing pattern is the reverse. The idea is that the second candle overturned all of the previous period's movement. In forex, where the market trades continuously and each candle usually opens where the last one closed, strict engulfing (which needs the second candle to open beyond the first one's close) is rarer than on equity charts, so many traders apply a looser definition.

Inside bar

A candle whose high and low are both within the range of the previous candle. It represents contraction, a pause. Traders often watch for a break of the inside bar's range, in either direction.

Morning star and evening star

Three-candle patterns. A morning star is a large bearish candle, then a small-bodied candle, then a large bullish candle that closes well into the first candle's body. An evening star is the reverse. Like the others, they describe a shift in control over three periods.

The limits of candlestick patterns

This is the section that matters most. Patterns are popular because they are easy to name and easy to spot. That is also the problem.

• They describe the past. A hammer tells you what happened during one period. It does not oblige the next period to do anything.
• Results are unreliable in isolation. A pattern appearing at random in the middle of a range has little meaning. The same shape at a significant level, after an extended move, is at least a more interesting piece of information. Context does the work, not the shape.
• Definitions are vague. How long must the wick be? How small the body? Different traders, books and software define them differently, so two people can disagree about whether a pattern exists.
• They change with the timeframe and the broker. A hammer on one broker's daily chart may not exist on another's if their daily close times differ.
• Hindsight makes them look better than they are. On a historical chart, your eye picks out the hammers that preceded rallies and skips the ones that preceded further falls. The only way to know whether a pattern helps your trading is to define it precisely and test it on a large sample, as described in how to backtest a strategy.

None of this means candles are useless. Reading them is the basic skill of understanding a chart. It means that a pattern is a reason to pay attention, not a reason to trade.

Putting candles in context

If you use candles as part of your process, three types of context make them more meaningful.

1. Location. Is the candle forming at a level where price has reacted before? Our guide to support and resistance covers how to identify those levels.
2. Trend. Is the broader market trending or ranging? A bullish signal against a strong downtrend is a different proposition from one in line with an uptrend. See trend following and moving averages.
3. Timing. Did the candle form during a major data release? A long wick created in the seconds after a US jobs report reflects a burst of volatility and thin liquidity, not necessarily a considered rejection of a price. Check the economic calendar and read how economic data moves forex.

Worked example: a hammer at a level, with a plan for being wrong

Illustrative numbers. GBP/USD has fallen for several days towards 1.2500, an area where it turned higher twice in recent months. A daily candle forms with these values: open 1.2540, high 1.2548, low 1.2488, close 1.2536. The body is 4 pips, the lower wick is 48 pips, and the upper wick is 8 pips. It fits the description of a hammer at a known level.

A trader who uses this as a setup might plan a long position as follows (this is an illustration of process, not a recommendation):

• Entry: above the hammer's high at 1.2550, so the trade only triggers if price continues higher.
• Stop-loss: below the hammer's low and the level, say 1.2475, giving a 75-pip stop. The reason is structural: if price breaks below both the wick and the level, the idea is wrong. See where to put a stop-loss.
• Size: with a £10,000 account risking 1%, the trader can lose £100. At 75 pips, that is about £1.33 per pip, or roughly 0.17 lots on GBP/USD where a standard lot is about $10 per pip, depending on the exchange rate. Our position sizing guide covers the calculation.
• Target: a previous swing high at 1.2700, 150 pips from entry, giving a reward-to-risk of 2:1. See risk-reward ratio.

Now the honest part. The trade may not trigger at all. If it triggers, price may still fall through the level and hit the stop. That outcome would not mean the trader read the candle wrongly; it would mean the candle, as always, did not predict the future. The point of the plan is that the loss is known and acceptable before the trade begins.

Other chart types

Candlesticks are not the only option.

• Line charts join the closing prices. They are clean and useful for seeing the broad shape of a trend, but hide the intraperiod range.
• OHLC bar charts show the same four prices as candles, with the open as a tick to the left and the close as a tick to the right. Some traders find them less visually loud.
• Heikin Ashi charts use averaged values to smooth the candles. They make trends look cleaner but do not show actual traded prices, so they should not be used for placing exact orders.

Common mistakes

• Trading every pattern you see. Most patterns form in the middle of nowhere and mean very little.
• Ignoring the timeframe. A bearish engulfing on a one-minute chart is not comparable to one on a weekly chart.
• Acting before the candle closes. The shape you are reacting to may not exist by the end of the period.
• Forgetting the spread. Candles usually show bid prices. Your buy orders fill at the ask.
• Learning dozens of pattern names instead of reading price. Understanding what the body and wicks say about the period is more useful than a long vocabulary.
• Relying on patterns without testing. If you plan to trade a pattern, define it precisely and test it, then track it in a trading journal.

Frequently asked questions

What do the colours of candlesticks mean?

They show whether the price closed higher or lower than it opened during the period. Most platforms use green (or white) for candles that closed higher and red (or black) for candles that closed lower. The colours are a setting, so check your platform rather than assuming.

What is the best timeframe for reading candlestick charts?

There is no single best timeframe. Higher timeframes, such as the four-hour and daily charts, show less noise and are often used for context. Lower timeframes show more detail but are noisier and more affected by spreads. Many traders combine a higher timeframe for direction with a lower one for planning entries.

Are candlestick patterns reliable?

Not on their own. A pattern describes what happened during one or a few periods and does not predict what comes next. Patterns are more meaningful at significant levels and in the context of the broader trend, and the only way to know whether one helps your trading is to define it precisely and test it.

What does a long wick on a candle mean?

It means price travelled a long way in that direction during the period but did not stay there by the close. A long upper wick shows higher prices were traded and then given back; a long lower wick shows the reverse. Around major data releases, long wicks often reflect brief volatility rather than a lasting change.

Why do candlestick charts look different on different brokers?

Brokers use their own price feeds and may close the daily candle at different times. A broker whose server day starts at a different hour from the 5pm New York convention can show different daily candles, including a small extra candle on Sundays. Prices can also differ slightly between feeds.

What is the difference between a candlestick chart and a bar chart?

Both show open, high, low and close for each period. A candlestick draws the open-to-close range as a coloured body; a bar chart shows the open and close as small horizontal ticks on a vertical line. The information is identical; the choice is visual preference.
