Candlestick charts: how to read price one candle at a time

Open any trading platform and you will almost always land on the same kind of chart: small green and red rectangles topped with thin lines. These are Japanese candlesticks. They became the standard because they pack a lot of information into a tiny space. Once you can read them, you see at a glance who controls the market, when, and with how much conviction.

In this lesson we will take a candle apart piece by piece, see how the timeframe changes everything, then learn to translate its shape into buying or selling pressure. It is the foundation for all the technical analysis that follows in this level.

How a candle is built

Each candle covers a fixed period: one minute, one hour, one day. During that period, price moves around. The candle keeps only four values, usually called OHLC: the open, the high, the low and the close.

1. The open: the first price quoted at the start of the period.
2. The high: the highest price reached during the period.
3. The low: the lowest price reached during the period.
4. The close: the last price quoted at the end of the period.

If the close is above the open, the candle is bullish: it is drawn in green (or white on classic charts). If the close is below the open, it is bearish: red or black. Colours can be changed on every platform, only the logic matters.

The body and the wicks

The body is the rectangle between the open and the close. It measures the net distance travelled during the period. A big body means one side dominated from start to finish. A small body means price ended roughly where it started, so nobody really won.

The wicks (also called shadows) are the lines above and below the body. The upper wick reaches the high, the lower wick reaches the low. A wick is a price the market visited and then rejected. A long upper wick tells you buyers pushed higher, then sellers drove them back before the close.

Timeframes

The same trading session can produce one daily candle or 24 one-hour candles. Timeframes are written with a letter and a number: M1, M5, M15 for minutes, H1, H4 for hours, D1 for the day, W1 for the week, MN for the month.

The smaller the timeframe, the more detail you see, but the more noise there is: random moves that mean nothing. The bigger the timeframe, the more weight each candle carries, because it aggregates more transactions. A daily candle that sharply rejects a level is worth far more than a five-minute candle doing the same thing.

Reading buyer and seller pressure

A candle is the summary of a fight. To read it, ask yourself three simple questions. Who won the period? By how much? And which prices were refused? The colour answers the first, the size of the body the second, the wicks the third.

• Big body, short wicks: one side controlled the whole period. A sign of conviction.
• Small body, wicks on both sides: indecision, the two sides cancel each other out.
• Long lower wick: sellers tried to push price down, buyers bought it back. Buying pressure into the close.
• Long upper wick: buyers were pushed back. Selling pressure into the close.
• Candle with no wicks: opens at the low and closes at the high (or the reverse). Total dominance, rare on higher timeframes.

A handy rule of thumb: compare the size of the body with the total range. If the body takes up more than two thirds of the candle, the winning side was clear. If it takes up less than a third, the period was mostly hesitation, whatever the colour.

Why context matters more than the candle

A long lower wick in the middle of a chart with no reference points teaches you almost nothing. The same wick touching a support tested three times, after a decline lasting several days, becomes serious information. Location gives a candle its value. We will cover support, resistance and trends in the next lessons.

Think about what comes next, too. A candle is only confirmed once it has closed: while it is still forming, its body and wicks can change completely. Many beginners enter on a candle that looks perfect halfway through, then watch it flip in the last few minutes.

In practice

To practise, open a D1 chart of EUR/USD or gold covering the last three months. For each candle, say out loud who won, by how much and which prices were rejected. After a few sessions this reading becomes automatic, and you will start spotting the candles that stand out, the ones that really matter. The next lesson shows you the most useful candlestick patterns.
