How to Read Candlestick Charts: OHLC, Body, Wick
Jan DreherMay 20266 min readA candlestick chart looks like secret code at first, yet every candle holds exactly the same simple information: 4 prices for a period. Once you can read those 4 numbers, you can read any chart in the world, from the 1-minute candle to the weekly candle.
OHLC: the 4 numbers of every candle
O for Open: the first price of the period. H for High: the highest. L for Low: the lowest. C for Close: the last. A candle contains nothing more. A green candle means the Close is above the Open, the price rose during the period. A red candle means the opposite. The color is not a judgment, just a direction indicator.
Body and wick: who had control
The thick part of the candle, the body, connects Open and Close and shows where the period ended net. The thin lines above and below, the wicks, show where the price went in between and was rejected again. A long lower wick with a small body means: sellers pushed, buyers bought all of it back. A long body without wicks means: one side had control the entire time. That is the real language of candles, the fight between buyers and sellers, compressed into a shape.
Candlestick patterns: an honest take
Patterns like hammer, engulfing, or doji describe recurring candle shapes, and they are useful as vocabulary. But the honest take that pattern lists leave out: a pattern on its own, in the middle of a chart, has about the predictive power of a coin flip. Patterns only get interesting in the right place: a hammer at a tested support after a sell-off tells a story, the same hammer in no man's land tells nothing.
- Hammer: long lower wick, small body on top. Sellers rejected, relevant at support.
- Engulfing: the body swallows the entire previous body. Momentum shift, relevant after a clear trend.
- Doji: Open equals Close, market undecided. Meaningless on its own, a warning sign after a long trend.
Timeframes: the same candles, a different story
A 4-hour candle is made of 48 5-minute candles. What looks like a crash on the small timeframe is often just a wick on the large one. That is why you read charts from large to small: first the daily and 4-hour chart for the picture, then the small timeframe for the entry. Anyone who only sees the 1-minute chart sees noise and mistakes it for information.
Candles do not tell you what the market will do. They tell you what it just did, and who had the upper hand while doing it. Nothing more, and that is enough.
How to practice reading charts, not just read about it
Reading charts is learned through repetition, not by memorizing pattern lists. In our interactive lessons you draw trend lines yourself and get honest feedback, and in bar replay you read real, anonymized charts candle by candle, without knowing how the story ends. That is as close to the live market as risk-free practice can be.
Frequently asked questions
Do candlestick patterns really work?
As a standalone signal, no: serious backtests show hit rates near random for isolated patterns. Patterns only gain their value from context: the market situation, the level, the preceding trend. A pattern is one sentence in a story, and anyone who reads only the sentence does not understand the story.
Which timeframe is best for beginners?
The 4-hour and the daily chart. There, candles carry more meaning, decisions do not need split-second reflexes, and the fee load from frequent trading disappears. Small timeframes like 1 and 5 minutes are the master discipline and the worst starting point.
What is the difference between a line chart and a candlestick chart?
A line chart connects only the closing prices and thereby discards 3 of the 4 pieces of information in each period. The candlestick chart also shows Open, High, and Low, so the movement within the period and its rejection too. For trading decisions the candlestick chart is therefore the standard.
How many candlestick patterns do I need to know?
A handful is enough: hammer, engulfing, doji, and their mirror images cover the essentials. More important than 40 names is the ability to read body and wicks as a fight between buyers and sellers, then you also recognize patterns without names. Pattern encyclopedias are busywork, not an edge.
