How to read candlestick charts

Every candle on a candlestick chart shows four prices for one slice of time: where price opened, the highest and lowest it traded, and where it closed. The thick body spans open to close, the thin wicks mark the extremes, and the color tells you whether price finished above or below its open. Read candles in groups and in context, not one at a time.

Four prices in every candle

A candle is a summary. Pick a timeframe, say one hour, and each candle compresses everything that traded in that hour into four numbers, usually shortened to OHLC:

• Open: the first price of the period.
• High: the highest price reached.
• Low: the lowest price reached.
• Close: the last price when the period ended.

What a candle leaves out is easy to forget. It does not record the order things happened in. A long lower wick could mean price fell early and spent the rest of the hour recovering, or drifted up, collapsed in the final minutes and bounced just before the close. If the order matters to you, drop to a lower timeframe and look.

Reading the body and the wicks

The body is the thick rectangle between open and close. Its length tells you how far price traveled from start to finish. A long body means one side pushed hard and still had control at the close. A tiny body means price ended roughly where it started, whatever happened in between.

The wicks, also called shadows, are the thin lines above and below the body. They mark prices that were reached and then rejected. A long upper wick says buyers pushed higher but could not hold it. A long lower wick says sellers drove price down and then lost control.

Read the three parts against each other:

• Big body, short wicks: one side ran the whole period.
• Tiny or no body, wicks on both sides: indecision, the shape of a doji or, with a slightly bigger body, a spinning top.
• Small body near the top, long lower wick: lower prices rejected, the outline of a hammer (or a hanging man if it appears after a rally).
• Small body near the bottom, long upper wick: higher prices rejected, the outline of a shooting star (or an inverted hammer after a decline).

"Long" and "small" are relative. Judge a candle against the ten or twenty before it, not against a dollar amount. A $50 range barely registers on Bitcoin, which trades in the tens of thousands, and would be an enormous day for silver.

Colors, and the thing they hide

Most charts draw a candle green (or hollow) when it closed above its open and red (or filled) when it closed below. Traditional Japanese charts used white and black. Platforms in mainland China and some other East Asian markets flip the convention and use red for up, so check the legend if a chart looks backwards.

The trap is that color compares a candle with its own open, not with the candle before it. Stocks and indices often open with a gap after the overnight break. If the S&P 500 opens well below yesterday's close and then claws back only part of that drop during the session, you get a green daily candle on a day the index finished lower.

So a green candle only tells you price rose from that candle's open. To know whether the market was up or down on the day, compare the close with the previous close.

Crypto trades around the clock, so gaps are rare and each candle usually opens right where the last one closed.

Why the same move looks different on 1m and 1D

A timeframe is the length of time each candle covers. Change it and identical price action turns into a different chart.

Take a hypothetical Bitcoin day. It opens at $60,000, sells off to $58,500 in the morning, climbs to a high of $61,200 in the evening and closes at $60,900.

• 1D chart: one green candle. Body $900 (60,000 to 60,900), lower wick $1,500 (down to 58,500), upper wick $300 (up to 61,200). It reads as sellers tried, failed, and buyers closed near the top.
• 1H chart: the same day becomes 24 candles. You might see a run of red candles in the morning, a cluster of small candles churning near $58,500, then a staircase of green candles into the evening. The "rejected low" turns into a visible selloff and recovery with its own structure.
• 1m chart: 1,440 candles. Most are noise, a few dollars up, a few down, wicks everywhere. Pattern shapes appear constantly and mean very little.
• 1W chart: the whole day is folded into one seventh of a single weekly candle, and the morning selloff may not even set that week's low.

That daily candle looks a bit like a hammer, but it fails the usual test of a lower wick at least twice the length of the body: $1,500 against $900 is not enough. Checking the numbers instead of eyeballing saves a lot of false reads.

As a rule of thumb, the higher the timeframe, the more trading sits behind each candle and the more weight its shape deserves. Many traders read direction on a higher timeframe and use a lower one only for timing.

Reading candles as a sequence

Single candles are words. Five to ten in a row make a sentence, and the useful question is what is changing across them.

• Bodies shrinking inside a trend. Three big green candles followed by two small ones: buyers are still winning, but by less each period. Fading momentum is not the same thing as a reversal.
• Wicks stacking at one price. Several candles with long upper wicks topping out near the same level show sellers defending it again and again.
• Where the closes land. Candles that keep closing near their highs show buyers in control into each close. Closes drifting to the middle of each range show a fight.
• One candle that breaks character. After days of small, quiet candles, a single long body closing outside the recent range says something new has happened.

Named multi-candle patterns are formal versions of these sentences. A bullish engulfing is a red candle followed by a green one whose body swallows the red body whole. A morning star is a long red candle, a small hesitant one, then a strong green one that closes well into the first candle's body: sellers running out of steam over three periods.

Location first, pattern second

The most common beginner mistake is spotting a named pattern and treating it as a signal wherever it shows up. A hammer in the middle of a choppy sideways range is just a candle with a long wick. The same hammer after a clear downtrend, sitting on a price where buyers stepped in twice before, deserves attention.

Before naming any pattern, answer three questions:

1. What is the trend on this timeframe, and on the one above it?
2. Is price at a level that has mattered before? Support and resistance is where patterns earn their meaning.
3. Is this candle unusually large or small compared with recent ones, and did volume pick up with it?

Only then look at the shape. Candlestick patterns are probabilistic hints. In the right context they may tilt the odds a little; in the wrong one they mean nothing, and even a textbook setup in the perfect spot fails regularly. Experienced traders pair every read with an exit plan and a position small enough to be wrong on.

A practice routine for your eye

Reading candles is pattern recognition, and that comes from repetition. One routine: pick a market, open the 1D chart, cover the right half of the screen and describe the last ten visible candles out loud (trend, body sizes, which side the wicks are on, where the closes land). Then uncover the rest and see what followed. Repeat on the 1H chart of the same market.

Live prices make it harder in a useful way, because you have to commit before you know the answer. In Alphacent's simulator you can open gold or Bitcoin on the daily chart (the 1H chart is Pro), write down what you expect over the next few candles, back the read with a paper trade from the $2,000 practice balance and check it later. The free Build a Candle tool shows exactly how moving the open, high, low or close reshapes a candle.

Once shapes start jumping out at you, work through the candlestick pattern library one pattern at a time rather than memorizing all of them at once.

Worked examples on this page use a hypothetical paper account and are for learning only, not advice. In Alphacent, free trades use a fixed $1,000 size; choosing your size, stop-loss and take-profit orders, and leverage are Pro features.
