How to read a candlestick chart: from one candle to the whole picture
You just bought your first coin, opened the markets page, and there it is — a screen full of little red and green blocks, none of which mean anything to you yet. This note is for exactly that moment. A candlestick chart is really just a price diary: every candle records where the price started, where it ended, how high it went and how low it dropped over one slice of time. You don't need any maths to read it. You just need someone to walk through it in order.
- The four prices hidden inside one candle, and which colour means up or down
- What the body and the upper/lower wicks are each telling you
- Why the same coin looks like two different things on a 1-minute chart and a daily one
- Roughly what those coloured lines on screen (moving averages, MACD) are for
- What reading a chart is actually good for — and what it simply can't do

The short version: what a candlestick chart is
A candlestick chart draws the price movement over a stretch of time as a row of little "candles". The format goes back to rice merchants in Edo-era Japan, who used it to track the price of rice; it later spread to financial markets everywhere, crypto exchanges included (Investopedia's entry on candlesticks has more of that history if you're curious).
You don't have to remember any of that. Hold on to one sentence instead: every candle on the chart shows what the price did during one fixed slice of time. That slice might be one minute, one hour, or a whole day — we call it the "timeframe", and we'll get to it. A single candle squeezes that slice down into four numbers and one colour, so you can tell at a glance whether the price rose or fell, and how hard.
So reading candles isn't fortune-telling. It's reading a record of what already happened. That distinction matters so much we wrote a whole separate note on it — why candles can't predict the future — and we'd suggest reading this one, then heading straight there.
One candle = four prices
Pick any single candle on the chart. It looks like a block with two thin whiskers, one above and one below. That shape records four prices, which traders call OHLC:
| Name | Short for | Where it sits on the candle |
|---|---|---|
| Open | Open | The price at the start of the slice of time |
| Close | Close | The price at the end of the slice |
| High | High | The highest point reached (the top of the upper wick) |
| Low | Low | The lowest point reached (the bottom of the lower wick) |
That thick block in the middle is the body, and its two ends are the open and the close. The thin lines poking out top and bottom are the wicks (some people call them shadows); they mark the highest and lowest the price touched during that slice.
A quick worked example, with rough, made-up numbers. Suppose you're on a 1-hour chart and one candle's hour plays out like this: trading opens at sixty thousand and a bit, dips for a while to a low near fifty-nine thousand, then climbs and peaks at around sixty-one thousand, before settling and closing at roughly sixty thousand five hundred. That single candle's OHLC is: open ~60,000, high ~61,000, low ~59,000, close ~60,500. Because the close (60,500) ended up above the open (60,000), the candle is green — the body runs from 60,000 up to 60,500, the upper wick reaches up to 61,000, and the lower wick drops down to 59,000. You never have to do this arithmetic by hand; the exchange draws it for you. The point of working it through once is to feel how four loose numbers turn into one little shape.
And notice what the candle quietly throws away: the order things happened in. Did the price hit the low first and the high later, or the other way round? A single candle can't tell you — it only keeps the four extremes, not the route between them. That's a real limitation worth holding onto, and one reason a candle is a summary, not a recording.
Green or red, up or down: check your own screen first
This is the very first trap, and the one beginners fall into most. On crypto exchanges, the default colours are usually green for up and red for down — a green candle means the close was higher than the open (it rose), red means the close was lower than the open (it fell).
Note that this is the opposite of some stock markets. Mainland China's A-shares, for instance, use red for up and green for down, so plenty of people coming over from stocks instinctively read crypto charts backwards. Worse, the colours can be swapped in the settings — some people genuinely prefer red-up, green-down. So the safe move is simple: before you read anything, confirm what green and red mean on this particular screen instead of guessing from habit.
This matters more than it sounds for a lot of beginners, because most people don't arrive at a chart through a stock broker at all. They bought their first bit of USDT through a P2P trade or a card top-up, swapped it for some BTC, and only then opened a chart to see "how it's doing". With no stock-market habit to fall back on, the colours are a pure coin-flip — and a wall of green can feel reassuring or alarming depending on which way you happened to guess. So don't carry over a rule from somewhere else, and don't take a friend's word for it either. Read one candle whose direction you already know (you watched the price tick up, and the candle is some colour), and now you know what that colour means on your screen. One candle settles it.
One afternoon we opened the BTC/USDT spot chart on the OKX web app, and the default was green-up, red-down. We went into the settings, swapped the up/down colours to red/green, and the same candle flipped colour on the spot — the price data hadn't changed at all, only the palette had. That's exactly why we keep saying it: colours can lie to you; the four OHLC numbers are the part that's real.
What the body and wicks are saying
Once you know the structure, the next step is reading it. The same four prices, arranged differently, give the candle a different shape — and each shape carries a different bit of market mood. Start with the three you'll see most:
- Long body, almost no wicks: one side (buyers or sellers) pushed from start to finish, and the price ran almost the whole way in one direction. That tells you one side was strongly in charge over that slice.
- Short body, long wicks top and bottom: the open and close ended up close together, but the price lurched up and down in between. Buyers and sellers were tugging back and forth and neither got the upper hand — common when the market is hesitating.
- Tiny body, almost a flat line: the open is roughly equal to the close. This is a doji, and it usually means no clear direction.
Wick length carries information too. If a candle has a long lower wick, the price dropped a long way at some point but got bought back up before the close — somebody was stepping in down there to catch it. Stack these shapes together and you get what people call candle patterns, which we name one by one (with pictures) in a few common candle patterns. For now, build one instinct: the body shows strength, the wicks show the back-and-forth.
Don't rush to memorise lines like "hammer means a bottom" or "engulfing means it'll rise". Get comfortable reading a single candle's four prices first, and the patterns will follow on their own — a pattern is just a handful of candles put together.
Many candles in a row make a chart
One candle is one slice of time. Line up the candles for many consecutive slices, left to right, and you've got the chart you're looking at. The far left is the oldest, and that unfinished candle on the far right is the slice that's "still in progress" right now — it stretches, shrinks and changes colour as the price moves, and only settles once the slice ends.
A lot of beginners stare at that twitching rightmost candle with their heart in their mouth. There's really no need. An unfinished candle can still change at any moment — it's green now, but it might close red three minutes later. The candles that are genuinely "final" are the ones that have already finished and stopped moving.
Timeframes: the same coin, two faces
This is the second big trap, and where beginners get "fooled" most. Take one coin, switch the timeframe from "1 minute" to "1 day", and the whole chart looks completely different.
The reason is simple: the timeframe is just "how much time each candle represents". On a 1-minute timeframe, each candle is one minute; on a daily timeframe, each candle is a whole day. A move that looks like a "crash" on the 1-minute chart might be nothing more than a small, unremarkable lower wick inside a single candle on the daily chart.
| Timeframe | Each candle is | Roughly good for |
|---|---|---|
| 1 min / 5 min | 1 / 5 minutes | Short-term watching; very noisy, easy for a beginner to get rattled |
| 1 hour / 4 hour | 1 / 4 hours | The rhythm over a few days; easier on the eyes |
| Daily / Weekly | A day / a week | The big direction, with the least interference |
This is behind a very common beginner panic. You buy a coin, flip to the 1-minute chart to "keep an eye on it", and watch it stab down a percent, recover, stab again — and your stomach goes with it. Switch that same moment to the daily and the coin has barely twitched. Nothing about the coin changed; you just zoomed all the way in and mistook the texture of normal trading for a crisis. The smaller the timeframe, the more of what you're watching is noise rather than anything that means a thing.
Our advice for beginners: start from the bigger timeframes like the daily and the 4-hour. The smaller the timeframe, the larger the share of random jitter (noise), and the easier it is to mistake meaningless wobble for a "signal". Bigger timeframes don't only filter noise — they're also kinder to your nerves, which for a beginner is half the battle. How to pick one is its own note: the 1-minute chart or the daily?
What those coloured lines are
Open a slightly "busier" candlestick chart and, besides the candles, you'll see a few coloured curves drifting over the top, maybe with a little window or two of bars hanging underneath. Those are technical indicators — helper lines calculated from past prices that let you look at the same move from a different angle. Beginners run into three most often:
| Indicator | In one line | Read more |
|---|---|---|
| Moving average (MA) | The last N days' average price drawn as a line; shows the trend direction and whether things are "expensive" | How to read moving averages |
| MACD | Uses the gap between two moving averages to show whether momentum is building or fading | How a beginner reads MACD |
| RSI | A number from 0 to 100 describing whether the recent move has gone up too far or down too far | RSI and overbought/oversold |
The one thing worth saying about all three now is that they're made from the same prices you can already see. A moving average is the candles' closing prices averaged; MACD is the gap between two of those averages; RSI is a tidied-up ratio of recent ups to recent downs. None of them reaches outside the chart for secret information — they reorganise what's in front of you so a pattern is easier to spot. That's useful, and it's also exactly why none of them can see the future: you can't squeeze tomorrow out of yesterday's numbers, no matter how you stir them.
One word of warning up front: more indicators is not better. The most common beginner mistake is to cram seven or eight indicators onto the screen at once, half-understand each of them, and watch them contradict each other. When two indicators disagree, beginners tend to believe whichever one says what they were hoping for — which is no longer reading a chart, it's reading your own wishes. Our suggestion is to get the candles themselves clear first, then add a single indicator at a time, learn it, and only then move to the next. Volume, by the way, gets overlooked a lot and matters more than people think — we put that in reading volume alongside price.
Finding all of this on the exchange screen
Theory's fine; now for the doing. Most exchanges lay out their charts in much the same way. We'll use OKX (formerly OKEx) as the example, because its web and mobile charting is fairly complete and it comes with a free demo account, which is ideal for a beginner to practise on over and over.
Step 1: find the markets / trade page
Open any trading pair (say BTC/USDT). The big chart in the middle is the candlestick chart.
Step 2: switch the timeframe
The row above the chart — "15m", "1H", "4H", "1D" — switches with a tap. Pick "1D" first to see the big direction.
Step 3: add one indicator
There's an "Indicators" button above the chart. Start with the moving average (MA), and don't pile on too many.
Step 4: practise on the demo account
Switch to demo trading and run through placing an order and reading the chart with virtual funds — a loss there doesn't sting.

What you're really reading a chart for
By now you might be quietly hoping: once I can read a chart, can I predict whether it'll go up or down? We have to be honest with you: no.
A candle records the past. What technical analysis can actually do for you is judge the current state (is it trending up or down right now, is it choppy or calm, are there obvious key price levels?) and manage risk (if I buy, at what price do I admit I was wrong and step out?). It gives you odds and discipline, not certain answers. No indicator and no pattern in any market can reliably predict the future — if one could, whoever invented it would be quietly getting rich, not selling you a course.
It's worth being concrete about why it can't. A chart only contains prices that already happened. Tomorrow's price depends on things the chart has never seen — a piece of news, a big holder deciding to sell, a regulator's announcement, the mood of thousands of strangers. A pattern that "worked" the last ten times has no memory and no obligation to work the eleventh; markets aren't a machine repeating a setting. On top of that, the moment a pattern becomes well known, enough people act on it that it starts to cancel itself out. So when you see a chart "calling" the next move with confidence, treat the confidence itself as the warning sign. The honest version is always probabilistic: "if this holds, I'd lean one way; if it breaks, I was wrong, and here's where I get out."
That's not a reason to give up on charts — it's the reason to use them for what they're actually good at. A chart can't tell you what happens next, but it can tell you where you'd be wrong, which is the one piece of information you can actually act on. Knowing your exit before you enter is worth more than any forecast.
So the real value of reading a chart is moving you from "buying on a hunch" to "knowing what you're betting on, and the most you could lose". That's why we treat how to place stop-loss and take-profit orders and the risk calculator as just as important as reading the chart itself. On what technical analysis can and can't do, we'd strongly suggest why candles can't predict the future.
Crypto swings hard, and contracts with leverage can wipe out all of your capital, and then some. Early on, practise with small amounts or a demo account only, and don't jump straight into leveraged contracts. Everything on this site is chart-reading education, not investment advice, and it won't make your buying decisions for you.
A minimal path for beginners
If you're not sure what order to learn things in, just follow this. Each step lines up with a note we've already written:
- Get comfortable reading a single candle → What one candle is telling you
- Learn a few common patterns and build a feel for the chart → A few common candle patterns
- Add your first indicator: the moving average → How to read moving averages
- Learn to protect yourself with orders → Limit, market, stop-loss and take-profit orders
- Practise on the live screen → Setting up the chart on OKX
- Finally, get clear on the limits of all this → Why candles can't predict the future
You don't have to get through it in a day. Reading charts is a slow skill — actually understanding one candle is worth far more than memorising the names of ten patterns.
One more honest word on pace. The temptation, once you've read a few of these notes, is to feel ready and to open a leveraged position to "test what you've learned". Please don't, not yet. Reading a chart and trading a chart are two different skills, and the gap between them is where most beginners lose their first chunk of money. Spend a week just watching — pick one coin, one timeframe, check it once a day, and try to say out loud what each new candle did and why the line looks the way it does. No orders, no stakes. If a week of that sounds boring, that's actually the lesson: most of good chart-reading is unexciting, and the people who last are the ones who made peace with that early. When you do start, start tiny, on the demo account first, and keep the risk note below in view the whole time.
Common questions
On a candlestick chart, is red up or down — and what about green?
On most crypto exchanges, including OKX, the default colours are green for up and red for down — the opposite of some stock markets. The colours can be changed in the settings, so before you read anything, check what green and red mean on your own screen.
Complete beginner — what should I learn first?
Start with the four prices a single candle records (open, close, high, low) and what the colours mean, then understand timeframes, and only then touch indicators like moving averages and MACD. Do it in the wrong order and it hurts.
Can reading candles predict where the price is going?
No. A candle records a price that has already happened. Technical analysis can help you judge the current state and the odds, but it can't guarantee the future. Anyone claiming candles let them predict prices reliably isn't being honest.
Which timeframe should a beginner watch?
Start from bigger timeframes like the daily and 4-hour. The smaller the timeframe, the more random noise there is, and the easier it is to mistake meaningless wobble for a signal. See the 1-minute chart or the daily?
