Reading Candlestick Charts
Four numbers in one shape, and why the body and the wicks have to be read together.
A candlestick shows four prices for one period: the open, high, low and close. The thick body spans the open and close, and the thin wicks above and below mark the highest and lowest prices traded. A close above the open is shaded one colour and a close below it another. Long wicks show price travelled somewhere and was pushed back before the period ended.
What to remember
- Read the body and the wicks together. A green candle that closed near its low after a 40-pip rejection is not a bullish candle.
- The same shape means different things in different places. A hammer mid-range is noise; a hammer at a level that has held twice is information.
- Candles describe a period that has already closed. Nothing in the shape obliges the next period to cooperate.
- Forex has no central exchange and therefore no true volume, so candle volume is a tick-count proxy.
Lesson 13 of 24 in Forex basics
A candlestick packs four numbers into one shape: the open, the high, the low and the close for a period of time. That is the whole format. The thick body spans the open and the close, and the thin wicks above and below reach to the highest and lowest prices traded. Once you can read those four numbers at a glance, a chart stops being a picture and becomes a record of what buyers and sellers actually did.
Anatomy of a single candle
Take a one-hour EUR/USD candle that opens at 1.0850, trades as high as 1.0872, as low as 1.0845, and closes at 1.0866. The body runs from 1.0850 to 1.0866 and is shaded as an up candle, because the close is above the open. The upper wick runs from 1.0866 to 1.0872, the lower wick from 1.0850 down to 1.0845. In that hour the pair travelled 27 pips of range but only finished 16 pips higher.
- A close above the open is normally shaded one colour, often green or white.
- A close below the open takes the other colour, often red or black.
- Long wicks show that price went somewhere and was pushed back before the period ended.
- A small body with long wicks shows a period where both sides pushed and neither finished in control.
The colour tells you nothing about the wicks, and beginners routinely read a green candle as bullish without noticing it closed near its low after a 40-pip rejection. Read the body and the wicks together or you are reading half the information.
Why candles beat a line chart
A line chart connects closing prices, which discards three quarters of what happened. Candles preserve the range and the sequence. That matters because a period that opened at the low and closed at the high tells a different story from one that spent the hour at the high and collapsed into the close, even though both may have the same close.
Candles also make the rhythm of a market visible. Long bodies in one direction, then a series of small ones, is a description of expansion followed by rest. That pattern is the visual basis of almost every trend and breakout approach covered in trading strategies.
