How to Read a Candlestick Chart

What a single candlestick actually shows you

A candlestick isn't just a colored bar. It's a compact summary of everything that happened to price during one chunk of time, whether that chunk is one minute, one hour, or one full day. Each candle packs four numbers into a single shape: the open (the price when the period started), the close (the price when it ended), and the high and low (the most extreme prices reached in between).

The thick middle part of the candle is called the body, and it stretches from the open price to the close price. The thin lines poking out above and below the body are called wicks, or shadows, and they mark the high and low the price touched during that period, even if it didn't stay there for long. If you run into unfamiliar terms as you go, our crypto and trading glossary is a good place to look them up.

What the colors mean

Most platforms color a candle green, or sometimes white or blue, when the close is higher than the open. That's called a bullish candle: it means buyers pushed the price up over that period. A candle colored red, or black, means the close was lower than the open, a bearish candle, which means sellers won that round.

That's the standard convention, but it isn't universal. Every charting platform lets you pick your own colors, and plenty of traders swap the defaults for other pairs, colorblind-friendly palettes being a common example. The shape and structure of the candle tell you the real story. The color is just a shortcut so you don't have to compare two numbers every single time.

Timeframes change what you're looking at

A candlestick chart is always tied to a timeframe, and that choice matters more than beginners usually expect. On a 1-hour chart, each candle represents everything that happened to the price across that one hour: the open, close, high, and low for those sixty minutes. Switch to a daily chart, and each candle now represents an entire day, compressed into that same shape.

The same asset can look completely different depending on which timeframe you're viewing. A coin might look like it's in a clean uptrend on the daily chart while chopping around wildly on a 5-minute chart. Neither view is wrong, they're just answering different questions about the same price history. Want to see this play out live?

A few basic patterns worth knowing

Once you can read a single candle, a handful of recurring shapes start to stand out. Here are three of the most talked-about, kept in plain terms.

• Doji. A candle where the open and close land nearly on top of each other, so the body is razor-thin, sometimes just a line. It signals indecision: buyers and sellers fought to a draw over that period, and neither side managed to push price meaningfully in one direction by the close.
• Long wick candles. When a candle has a long wick on one side, say a long lower wick under a small body near the top, it means price got pushed hard in one direction during the period and then got rejected, reversing back to close near where it started. A long lower wick suggests sellers tried to push price down and buyers stepped in; a long upper wick suggests the opposite happened.
• Big-bodied candles. A candle with a large body and small or no wicks shows strong conviction. Price moved decisively in one direction for the whole period with little pushback, which usually reflects a stretch where one side, buyers or sellers, was clearly in control.

Why you shouldn't trade off a single candle

Here's the part that's easy to skip past: candlestick patterns are, at best, probabilistic tendencies, not rules. A doji doesn't guarantee a reversal is coming, and a long wick doesn't guarantee that a support or resistance level will hold. These shapes describe what already happened during that period. They don't come with a promise about what happens next.

Most traders who use candlestick patterns don't trade them in isolation. They combine what a candle looks like with other context: the trading volume during that period, whether it formed near a known support or resistance level, and what other indicators are showing at the same time. A doji that forms in the middle of nowhere means a lot less than one that forms right at a level price has bounced off before. Once you've spotted a setup you actually want to act on, it helps to know how orders get filled in the first place, which is what our order types guide covers.

Why candlesticks replaced line charts

Before candlesticks became the default, a lot of traders got by on line charts, a single line connecting closing prices over time. That's fine for a quick glance at the overall trend, but it throws away most of the information. A line chart tells you where price ended up. It doesn't tell you how it got there, how far it swung along the way, or who was winning the fight between buyers and sellers during that stretch.

Candlesticks kept the closing price but added the open, high, and low back in, so you can see a period's full range at a glance, plus the direction it resolved in. That extra detail, packed into a shape you can scan quickly across dozens of candles at once, is why they became the standard view on nearly every trading platform out there.
