Candlestick chart

What a candlestick chart means

A candlestick chart is a way of drawing price history in which each period is shown as a single candle. One candle summarises four numbers for that period: the open, the high, the low and the close. The period can be anything the chart is set to, from one minute to one month. Candlestick charting is usually traced to rice traders in Japan centuries ago, and was brought to a wide audience in the West in the late twentieth century.

Each candle has two parts. The body is the thick rectangle between the open and the close. The wicks, also called shadows or tails, are the thin lines extending from the body up to the high and down to the low. Colour shows direction. By convention in many platforms a candle is green or white when the close is above the open, and red or black when the close is below the open, but platforms let you change the colours, so always check the legend.

Compared with a simple line chart that connects closing prices, candlesticks show far more about what happened inside each period, such as how far price travelled and where it ended relative to its range.

How it works

Reading a single candle involves a few questions.

1. Where did the period open and close? The body tells you.
2. How big is the body relative to the wicks? A large body suggests one side was in control, while a small body suggests indecision.
3. How long are the wicks? A long upper wick means price rose but was pushed back. A long lower wick means price fell but recovered.
4. Where does the close sit in the range? A close near the high suggests buyers finished strongly, and near the low suggests sellers did.

Traders also name common shapes. A doji has an open and close almost equal, forming a cross. A hammer has a small body with a long lower wick. A shooting star has a small body with a long upper wick. An engulfing pattern is a candle whose body fully covers the previous one's body. Marubozu candles have almost no wicks.

Patterns are interpreted in context, such as after a long move, near a support or resistance level, or alongside volume. No single shape has a dependable outcome on its own.

A worked example

These numbers are illustrative. On an hourly EUR/USD chart, one candle has an open of 1.0820, a high of 1.0875, a low of 1.0805 and a close of 1.0860.

• Close is above open, so the candle is bullish by convention.
• Body = 1.0860 − 1.0820 = 0.0040, or 40 pips.
• Upper wick = 1.0875 − 1.0860 = 0.0015, or 15 pips.
• Lower wick = 1.0820 − 1.0805 = 0.0015, or 15 pips.
• Total range = 1.0875 − 1.0805 = 0.0070, or 70 pips.
• Body as a share of the range = 40 ÷ 70 = about 57 percent.
• Close sits (1.0860 − 1.0805) ÷ 0.0070 = 0.0055 ÷ 0.0070 = about 79 percent up the range.

Read plainly, buyers controlled most of the hour and closed near the high, but sellers briefly pushed the price down to 1.0805 and back up to 1.0875 before the close. It describes what occurred. It does not state what will happen next.

Why it matters

Candlesticks are the default chart type on most trading platforms and in educational material, so being fluent in them is practically essential. They compress a lot of information into a small visual unit, which helps with spotting momentum shifts, rejection of price levels and volatility changes at a glance.

They also help with defining risk. Stop-loss placement is often set beyond a recent candle's high or low. Understanding wicks reminds you that price can briefly move through a level without closing beyond it, so an order can be triggered by a spike that the closing price ignores.

Charts can differ between brokers, since the open and close of each candle depend on the data feed, the time zone and when the daily candle is cut off. Differences in feeds explain why two platforms might show slightly different highs and lows.

How to use it in practice

• Set the timeframe that matches your style, and check the same market on one higher timeframe for context.
• Confirm what price the chart uses, bid or last, and what time the daily candle closes.
• Focus on candle context, such as position relative to support, resistance or a moving average, before giving weight to any pattern.
• Wait for a candle to close before treating it as a completed pattern. An open candle can change shape until the period ends.
• Combine candle reading with volume or a volatility measure like ATR if available.
• Keep a journal of patterns you act on, and measure how they perform, including costs.

Common mistakes and misconceptions

• Treating pattern names as signals. Studies of pattern reliability are mixed, and results depend on context.
• Judging an unfinished candle as final.
• Ignoring the timeframe. A pattern on a one-minute chart has little in common with the same shape on a weekly chart.
• Assuming green always means buy. Colour describes the period only.
• Forgetting that the spread and the data feed alter the highs and lows.
• Memorising dozens of patterns instead of learning to read the balance between body and wick.

Risks and limitations

Candlestick analysis is descriptive and subjective. Two traders can read the same candle differently, and patterns often fail, especially in choppy markets. Hindsight makes patterns look more reliable than they are in real time. Acting on a candle in a leveraged product can cause fast losses, and spreads and slippage can cancel a small expected edge. Nothing here is a trading signal.

How Brokeli looks at it

Charts are part of the platform you will actually use daily, so in our research we note which chart types, timeframes and indicators are offered, how price data is sourced, and what the platform supports for different instruments. We use published research snapshots for those facts rather than judging a broker by its charts alone.
