How to Read Stock Charts: A Beginner's Guide to Candlesticks (2026)

How do you read candlestick charts for stocks?

Read each candlestick as one period's four prices: the thick body spans the open and the close, and the thin lines above and below it, called wicks or shadows, mark the high and the low. In Fidelity's Learning Center description, a close above the open leaves the body hollow (white or green) and a close below the open fills it in (black or red). Then judge the body and shadows in context, and treat any pattern as a possible signal that still needs confirmation.

A chart is simply a row of these candles. Fidelity defines a stock chart as a visual representation of a security's price over a set period of time, with price on the vertical axis, time on the horizontal axis and the most recent plot furthest right, and each candle can stand for a day, a week or a month depending on the time frame you choose.

This guide is assembled from Fidelity's Learning Center and StockCharts' ChartSchool definitions (checked October 2026), rather than first-hand trading, and it contains no invented win rates or backtests. Use it as general information, not financial advice: investing involves risk, and no chart pattern removes it.

The anatomy of a candlestick

Every candle is built from the same four numbers. StockCharts puts it plainly: to create a candlestick chart, you must have a data set that contains open, high, low and close values for each time period you want to display.

Colors vary by platform, so check your charting tool's legend. The logic doesn't change: on a hollow candle the bottom of the body is the open and the top is the close, and on a filled candle the top of the body is the open and the bottom is the close.

Step 1: Choose the time frame before you read anything

The same stock can tell two different stories depending on the time frame. Fidelity's example: a downtrend could clearly be present in a 1-month chart, but switch the same chart to 1 year and that 1-month downtrend could look more like a minor correction amid a much longer-term bullish uptrend.

Fidelity's advice is to match the chart to your horizon. If you are a longer-term investor with a 1- to 10-year time horizon, looking at an intraday or 1-week chart wouldn't make much sense, while a multi-year chart would probably not suit a short-term momentum trade. Looking at different time frames can help you understand the whole picture.

Step 2: Read the body

The body tells you who won the period, and by how much:

• Long bodies. Generally speaking, the longer the body is, the more intense the buying or selling pressure, according to StockCharts.
• Short bodies. Short candlesticks indicate little price movement and represent consolidation.
• Hollow versus filled. Hollow candlesticks, where the close is greater than the open, indicate buying pressure; filled candlesticks, where the close is less than the open, indicate selling pressure.
• No shadows at all. A white Marubozu forms when the open equals the low and the close equals the high, meaning buyers controlled the price action from the first trade to the last; a black Marubozu is the mirror image for sellers.

Position matters as much as size. StockCharts notes that while long white candlesticks are generally bullish, much depends on their position within the broader technical picture: after extended declines, a long white candle can mark a potential turning point or support level.

Step 3: Read the shadows

Shadows show how far price traveled beyond the open and close. Upper shadows represent the session high and lower shadows the session low.

• Short shadows mean most of the trading action was confined near the open and close.
• A long upper shadow with a short lower one means buyers dominated during the session, bidding prices higher, but sellers ultimately forced prices down from their highs.
• A long lower shadow with a short upper one means sellers drove prices lower, but buyers later resurfaced to bid prices higher by the end of the session.
• Long shadows on both sides with a small body form a spinning top, which StockCharts reads as indecision: neither buyers nor sellers could gain the upper hand.

Step 4: Learn the common one-candle shapes

A handful of shapes come up constantly. The definitions below are ChartSchool's; the meaning of each depends on what came before it.

For the long-shadow shapes, StockCharts says that generally, the long shadow should be at least twice the length of the real body. It also stresses that doji alone are not enough to mark a reversal.

Step 5: Spot the two-candle engulfing patterns

The bullish engulfing pattern consists of two candlesticks, the first black and the second white, and the white body must totally engulf the body of the first black candlestick. After a decline, the second candle opens below the prior close, then buyers push prices above the previous open for a strong finish. Generally, StockCharts adds, the larger the white candlestick and the greater the engulfing, the more bullish the reversal. The bearish engulfing pattern is the reverse, two candlesticks with the first white and the second black, and ChartSchool shows it blending into a shooting star when the two candles are combined.

Context decides whether either one counts. Bullish reversals require a preceding downtrend and bearish reversals require a prior uptrend, so a bullish engulfing at new highs can hardly be considered a bullish reversal pattern. Because candlesticks are short-term, StockCharts suggests it is usually best to consider the last 1-4 weeks of price action when judging that trend.

Step 6: Wait for confirmation and check the bigger picture

Confirmation is what turns a shape into a signal. ChartSchool's guidelines for bullish reversal patterns say most require bullish confirmation, and that without it they would be considered neutral and merely indicate a potential support level at best. Bullish confirmation means further upside follow-through, such as a gap up, a long white candlestick or a high-volume advance, and because candlestick patterns are short-term and usually effective for only 1 or 2 weeks, it should come within 1 to 3 days after the pattern.

Candles also work best alongside other tools. StockCharts recommends combining them with support and resistance levels, momentum oscillators and volume-based indicators, and its own summary is worth keeping in mind: technical analysis is not an exact science; you must look for confirming signals to build evidence to support a likely outcome.

What a candlestick can't tell you

A candle compresses a whole session into four prices, and something gets lost. Candlesticks don't reflect the sequence of events between the open and close: the high and the low are indisputable, but candlesticks (and bar charts) cannot tell us which came first. ChartSchool illustrates this with two very different sessions, one with a single sharp advance and one with three sharp swings, that draw the same long white candle.

That is also why this page gives no pattern "success rates." The sources quoted here don't publish them, and a pattern's meaning shifts with the trend before it and the confirmation after it. Fidelity's own note is that candlestick charts are most applicable for advanced chart users who are familiar with candlestick pattern analysis, so expect a learning curve.

Candlesticks versus line and bar charts

Fidelity lists three main chart types, and the candlestick is one way to draw the same data:

Fidelity says candlestick charts are very similar to OHLC charts in that they provide the same information, just in a different format, and that many traders like them because they can present the information on one particular day's trading in a quicker, easier-to-read format. It also says one chart type is not necessarily better than the next, and on Fidelity.com, Candle charts are the default option.

A reading routine you can repeat

1. Set the time frame to match your horizon, then glance at a longer one for context.
2. Find the trend first. StockCharts' examples of a downtrend include a security trading below its 20-day exponential moving average, each reaction peak and trough lower than the previous, or a security trading below its trend line.
3. Read the latest candles: body length and color, then shadow length.
4. Name a pattern only if the prior trend fits it.
5. Wait for confirmation, and check it against support, resistance and volume.

Where to go deeper

Two books cover this ground in depth. John J. Murphy's Technical Analysis of the Financial Markets is a standard reference on chart reading (Check price on Amazon; see our Technical Analysis of the Financial Markets review). Steve Nison's Japanese Candlestick Charting Techniques, which ChartSchool lists for further study, is the classic on candlesticks themselves; our Japanese Candlestick Charting Techniques review covers what it includes.

If you plan to apply charts to intraday trading, Andrew Aziz's How to Day Trade for a Living is a beginner-level book on the subject (Check price on Amazon; see our How to Day Trade for a Living review). Our guide to stock screeners for day trading covers the tools that find charts worth reading, and for the brokers and platforms whose charts you would use, see our full shortlist.

FAQ

What do green and red candles mean on a stock chart?

A green (or hollow, or white) candle means the close was higher than the open, and a red (or filled, or black) candle means the close was lower than the open. Fidelity describes these as an up day and a down day in traditional candlesticks; the colors are a platform setting, so check your chart's legend.

What does a doji candle mean?

A doji forms when a security's open and close are virtually equal, leaving a thin-line body. StockCharts reads it as indecision between buyers and sellers: neutral on its own, and more meaningful after a strong advance or decline, but never enough to mark a reversal without confirmation.

What time frame should a beginner use for candlestick charts?

Match it to how long you plan to hold. Fidelity's guidance is that a longer-term investor gains little from intraday or 1-week charts, a short-term trader gains little from multi-year ones, and looking at more than one time frame can provide needed context.

Are candlestick patterns reliable?

No source quoted here publishes a success rate for them. ChartSchool says most patterns require confirmation, that a reversal pattern needs a prior trend to reverse, and that technical analysis is not an exact science.

Is a candlestick chart better than a bar chart?

Neither is better; they show the same open, high, low and close. Fidelity says candlesticks present that information in a quicker, easier-to-read format for many traders, and that one chart type is not necessarily better than the next.
