Open any trading app and the first thing you see is a chart full of small red and green bars. Those are candlesticks, and once you can read them, a price chart stops looking like noise. This guide explains candlesticks from the ground up, the way we teach them in week one of our trading classes in Pune.
You'll learn what each part of a candle means, how to read a few candles together, which patterns are worth knowing, and why no single candle ever tells you what will happen next. All examples use market data at least 30 days old.
- Each candle shows four prices: open, high, low and close.
- The body shows the open-to-close move, the wicks show how far price travelled.
- Context matters more than any single pattern.
- Candles describe what happened, they don't predict what happens next.
- Always combine candles with levels, trend and risk rules.
What a candlestick shows
A candlestick summarises price movement over one period of time: one day, one hour or five minutes, depending on the chart you choose. Every candle carries four prices. The open is where the period started, the close is where it ended, the high is the highest price reached and the low is the lowest.
The thick part of the candle is the body. It runs from the open to the close. The thin lines above and below are the wicks, sometimes called shadows. They show the high and the low. With just these four numbers, one candle tells you who was in control during that period and how much they had to fight for it.
Green and red candles
When the close is higher than the open, the candle is usually green or hollow. Buyers pushed the price up over the period. When the close is lower than the open, the candle is usually red or filled. Sellers pushed it down.
Colours are only a convention, and different apps use different schemes. What matters is the relationship between open and close. Always check your app's settings once, so you're sure which colour means what.
Reading the body and the wicks
A long body means one side was in clear control for most of the period. A short body means buyers and sellers were close to balanced. Long wicks show rejection: price went somewhere and was pushed back.
For example, a candle with a long lower wick and a close near its high tells you that sellers pushed the price down during the period, but buyers stepped in strongly and pushed it back up. Where that candle appears on the chart decides whether it matters.
Timeframes: daily, hourly and minutes
The same stock can look completely different on different timeframes. A daily chart shows one candle per trading day and suits swing traders and investors. A 15-minute or 5-minute chart shows the detail within a day and suits intraday traders.
Beginners should start with daily charts. They are calmer, less noisy and easier to read. Once you can describe a daily chart confidently, shorter timeframes make much more sense.
Single-candle patterns worth knowing
A doji has a very small body, with the open and close almost equal. It shows indecision. A hammer has a small body near the top and a long lower wick, showing buyers rejecting lower prices. A shooting star is the opposite, with a long upper wick showing sellers rejecting higher prices.
These names are useful shorthand, but none of them is a signal on its own. A hammer in the middle of nowhere means very little. A hammer at a level where buyers have stepped in several times before is worth paying attention to.
Two and three-candle patterns
An engulfing pattern happens when one candle's body completely covers the previous candle's body in the opposite direction. A bullish engulfing after a fall shows buyers suddenly taking control. Inside bars, where a candle stays entirely within the previous candle's range, show a pause before the next move.
Three-candle patterns like the morning star and evening star describe a change of control over three periods. They are easy to spot in hindsight and much harder in real time, which is why we practise them on past charts before anyone trades them.
Context matters more than patterns
The most common beginner mistake is treating patterns like buy and sell buttons. In reality, the same pattern means different things in different places. A bullish candle near a strong resistance level is far less meaningful than the same candle near support in an uptrend.
Before looking at any candle, ask three questions. What is the trend? Where are the nearby support and resistance levels? Is volume higher or lower than usual? Only then does a candle start telling you something useful.
Using volume with candles
Volume shows how many shares traded during each candle. A big move on high volume shows real participation. The same move on very low volume can be fragile and easy to reverse.
When a breakout candle closes above resistance on strong volume, more traders are behind the move. When a pullback happens on falling volume, sellers may not be very committed. Volume doesn't predict the future either, but it adds weight to what the candles are showing.
Reading candles at support and resistance
Support is a price area where buying has stopped falls before. Resistance is an area where selling has capped rises. Candles become much more meaningful at these levels, because that is where buyers and sellers are most likely to fight.
A long lower wick right at support shows buyers defending the level. A strong close above resistance shows buyers winning a fight they have lost before. The same candles in the middle of a range, away from any level, usually mean far less. In class, students mark levels first and only then read the candles.
Gaps and what they tell you
A gap appears when a candle opens well above or below the previous candle's close, leaving an empty space on the chart. Gaps usually follow news, results or big moves in the wider market overnight.
Some gaps fill quickly as price returns to the previous close. Others mark the start of a strong move. There is no rule that decides which, but gaps on high volume at important levels tend to matter more. Gaps are also why stop losses sometimes fill at worse prices than planned.
A worked example on past data
Imagine a large company's daily chart from several months ago. For three weeks it made higher highs and higher lows. Then it pulled back for four days on falling volume, towards a level where it had bounced twice before.
On the fifth day, a candle opened lower, dipped below the level, and then closed near its high with a long lower wick. That told us buyers had stepped in at the level again. The next day, a candle closed above the previous day's high on higher volume. Together, the trend, the level, the wick and the volume told a clear story. Even then, a sensible plan would place a stop just below the wick's low, because the story can still be wrong.
Heikin-Ashi and other chart types
Most apps also offer Heikin-Ashi candles, which average price data to make trends look smoother. They can help you see the direction more clearly, but the prices on them are not the actual open, high, low and close.
Line charts connect closing prices only, and bar charts show the same four prices as candles in a different shape. Beginners should learn normal candlesticks first, because they show exactly what happened. Other chart types are useful later, once you understand what they hide.
Common candlestick mistakes
Trading every pattern you see. Ignoring the trend. Reading short timeframes before daily charts. Forgetting that patterns fail, sometimes often. Entering without a stop loss because a pattern "looks strong".
Candles are a language for describing price. Used with levels, trend and strict risk rules, they are very helpful. Used alone, they turn into guesswork with fancy names.
How to practise reading candles
Take a daily chart of a large company from a few months ago. Cover the right side of the chart, read the last few visible candles, and write down what you think buyers and sellers were doing. Then uncover the next candle and compare.
Do this for ten charts a week and your reading improves quickly. In our trading course, this exact exercise runs through the first two weeks, with Sharad reviewing students' notes every Thursday.
Common beginner questions
Are candlestick patterns reliable?
No pattern works every time. Candlestick patterns show what buyers and sellers did, not what they will do next. They become more useful when combined with trend, support and resistance levels, volume and a clear stop loss.
Which timeframe should beginners use for candlestick charts?
Start with daily charts. They are less noisy and easier to read. Move to shorter timeframes like hourly or 15-minute charts only after you can describe a daily chart confidently.
What is the difference between a candlestick chart and a line chart?
A line chart only connects closing prices. A candlestick chart shows the open, high, low and close for each period, so you can see how price moved within the period and where it was rejected.
How long does it take to learn candlestick charts?
Most people learn the basics in a few days. Reading them well in context takes a few weeks of regular practice on past charts, which is why our trading course practises this every week.
What does a long wick on a candlestick mean?
A long wick shows that price moved far in one direction during the period but was pushed back. A long lower wick shows buyers rejecting lower prices, and a long upper wick shows sellers rejecting higher prices. Its meaning depends on where it appears.
Should I use Heikin-Ashi candles as a beginner?
It is better to start with normal candlesticks, because they show the real open, high, low and close. Heikin-Ashi candles smooth price data, which can hide important details until you understand how they are calculated.
