How to Read Candlestick Charts: A Beginner's Guide

Written by DUOCODE TECHNOLOGYPublished and reviewed 9 min read

A candlestick chart shows how price moved during a fixed period—one minute, one hour, one day—by drawing four numbers for that period: the open, high, low and close (OHLC). Each candle is a compact picture of a battle between buyers and sellers over that slice of time. Learning to read candles is really learning to read those four numbers at a glance, then noticing how one candle relates to the next.

This guide explains what the body and wicks mean, walks through a few widely described patterns, and is honest about their limits. Candlestick patterns are descriptions of what already happened, not predictions that must repeat. They do not carry a guaranteed outcome, and no single candle tells you what a market will do next. The most useful skill is reading them accurately and testing them, which you can do risk-free on Tradrill.[1]

Short answer

  • Each candlestick encodes four prices for one time period: open, high, low and close (OHLC).
  • The body shows the open-to-close range; the wicks show the high and low; colour shows whether the close was above or below the open.
  • Patterns describe past price behaviour—they are not guarantees, so read them as context and test them in practice, never as signals.

The anatomy of a single candle

Every candlestick represents one time period on your chart. The rectangular part is the body, drawn between the opening price and the closing price. The thin lines above and below—called wicks or shadows—reach up to the highest price and down to the lowest price traded in that period. Together they show the full range and where price started and finished.

Colour (or fill) tells you direction. A typical convention makes an up candle—where the close is higher than the open—green or hollow, and a down candle—where the close is lower than the open—red or filled. A long body means the open and close were far apart, showing strong one-way movement; a short body means they finished close together, showing indecision. Long wicks show that price reached a level but was rejected before the period ended.

Reading a candle is simply naming those parts out loud: where did it open, how far did it travel up and down, and where did it close relative to the open? Do that consistently and the chart stops being decoration and becomes a record of who was in control during each period.

  • Body: the range between the open and the close for that period.
  • Wicks (shadows): the thin lines marking the high and the low.
  • Colour: up candle (close above open) versus down candle (close below open).
  • Body length: long bodies show conviction, short bodies show indecision.

A few common patterns—and what they describe

Patterns are just recognisable shapes made by one or a few candles. A doji has almost no body because the open and close are nearly equal, describing a period of indecision. A hammer has a small body near the top with a long lower wick, describing a session where sellers pushed price down but buyers pulled it back by the close. An engulfing pattern is a candle whose body fully covers the previous candle's body, describing a shift in short-term momentum.

It is important to hold these loosely. A pattern describes what buyers and sellers just did; it does not promise what they will do next. The same shape can appear before a reversal, a continuation or nothing at all. Regulators warn that trading is risky and that past behaviour does not guarantee future results, and hypothetical or pattern-based reasoning has inherent limitations because it is read with hindsight.[2] [4]

Candlestick patterns are descriptions of past price action, not predictions. They carry no guaranteed outcome and are not trade signals.

How to practise reading candles

The fastest way to learn is to read many candles deliberately rather than memorising a list of pattern names. Pick one timeframe, cover the right side of the chart, and predict out loud what the next candle's open, high, low and close might mean—then reveal it and check your reading. You are training observation, not fortune-telling, so score whether you described the candle accurately, not whether you guessed the direction.

Doing this with virtual money removes the pressure that distorts learning. On Tradrill you can step through historical price bar by bar, read each candle, and note what happened next without any capital at risk. Keep it honest: a pattern that seemed to work a few times is not proof it will keep working, and a clean practice run is not a performance claim.[3]

  1. Fix one timeframe

    Choose a single period (for example daily or 5-minute) so every candle means the same slice of time while you learn.

  2. Name the parts

    For each candle, say the open, high, low and close and whether it closed up or down before moving on.

  3. Read relationships, not omens

    Notice how each candle relates to the one before it—bigger body, longer wick, higher close—without assuming what comes next.

  4. Test in simulation

    Replay historical bars on Tradrill, log what you read, and review your accuracy separately from any simulated profit.

Candle-reading checklist

Use this to build accurate reading habits before you rely on candles for any decision.

  • I can identify the body, the wicks and the colour on any candle.
  • I know the body shows open-to-close and the wicks show the high and low.
  • I can describe a doji, a hammer and an engulfing candle in plain words.
  • I treat patterns as descriptions of the past, not predictions or signals.
  • I practise reading candles on historical data with no real money at risk.

Frequently asked questions

What do the parts of a candlestick mean?
The body is drawn between the open and close prices for that period, and the thin wicks reach to the high and the low. Colour shows direction: an up candle closes above its open, a down candle closes below. So a single candle summarises four prices—open, high, low and close—for one slice of time.
Are candlestick patterns reliable?
Patterns describe what buyers and sellers just did; they do not guarantee what happens next. The same shape can precede a reversal, a continuation or nothing. Treat them as context to study and test, not as signals, and remember regulators warn that past behaviour does not guarantee future results.
What timeframe should a beginner start with?
Pick one timeframe and stay on it while you learn, so every candle represents the same amount of time. Many beginners find daily candles easier to read because each one covers a full session. The goal is consistent, accurate reading rather than switching timeframes looking for a pattern.
How can I practise reading candles safely?
Use a simulator with historical data so no real money is at risk. On Tradrill you can step through price bar by bar, read each candle, and check what happened next. Score whether you read the candle accurately, and remember a good practice run is not proof of live results.
