How to Read a Stock Chart: Candles, Trend, Levels and Volume

Reading a stock chart is a stack of small skills: the settings, the candles, the trend, the levels, volume and a couple of indicators. None of it predicts the next candle. I trade momentum and build an AI chart grader, so this guide ends with a worked example and what a screenshot read can and can't see.

How Do You Read a Stock Chart?

The U.S. News guide to reading stock charts calls one "a graph showing the price of a stock over time". Everything else on the screen tells you how price got there and how hard each side pushed.

What are the parts of a stock chart?

Price runs up the vertical axis, usually on the right edge, and time runs along the bottom. Fidelity's Learning Center describes the order as "the most recent plot being the furthest right", so the candle on the right edge is the newest one, often still forming. The panel under the price is volume. The lines through the candles are whatever indicators you've switched on. The text in the top-left corner is the legend: the symbol, the timeframe, and an open, high, low and close.

Two details trip people up. On charting platforms like TradingView, the legend's O, H, L and C belong to the candle under your cursor (or the latest candle when you're not hovering), not to the whole day. And the price scale rarely starts at zero, so a move that fills the screen can be a 2% move. Charts that cover years are often easier to read on a log scale, which the guide to log vs linear chart scales explains.

What Are the Three Main Types of Stock Charts?

Line, bar and candlestick. All three are drawn from the same prices. They differ in how much of each period they show you.

Line charts are the plainest. Schwab's guide to stock charts and trading patterns describes one as "a single line that connects all closing prices of a stock". You get the big picture fast and lose everything inside each period. Fine for a five-year view, not enough for a trade.

Bar charts, also called OHLC charts, draw each period as a vertical line from the high to the low. In Schwab's words, "the left line represents the open, and the right line represents the close." The bar's height is the period's range, which is why "As the market becomes increasingly volatile, the bars become larger".

Candlestick charts show the same four prices as a bar but fill in the space between the open and the close, so up and down periods jump out by color. Investopedia's chart guide calls candlesticks "the go-to for most traders". Quote pages, meanwhile, often open on a line chart by default. The rest of this guide uses candles.

Other chart types exist, mostly to filter noise. Heikin-Ashi candles are built from averaged prices, so trends look smoother. Renko bricks and point and figure charts ignore time and only print when price moves a set amount. Learn standard candles first. The others make more sense once you can read the original.

What does the timeframe on a chart mean?

The timeframe is how much time each candle covers. On a daily chart every candle is one session, and on a 5-minute chart it's five minutes. Investopedia's chart guide notes that "charts are available in timeframes ranging from 1 minute to 1 month".

Don't confuse it with the range. The 1D, 5D or 1Y buttons on a quote page set how much history is on screen. The interval sets what each candle covers, and one day drawn in 1-minute candles looks nothing like the same day in 15-minute candles. Check both settings before you read anything.

Match the timeframe to your holding period. Fidelity's chart setup advice is "Choose a time frame that matches your investment horizon". Swing trades live on the daily chart. Day trades live on the 1- to 15-minute charts, with the daily for context (more on that below). StockCharts' ChartSchool warns that "short-term charts can be volatile and contain a lot of noise", which is why I'd learn on daily charts first.

How Do You Read a Candlestick?

A candle is four prices in one shape. The body is the thick part, from the open to the close. The thin lines above and below are the wicks, also called shadows. The top of the upper wick is the period's high and the bottom of the lower wick is its low.

If the open and the close are the same price, there's no body, only a line across the wicks. That candle is a doji.

The default colors: green (or white, or hollow) closed above its open, and red (or black, or filled) closed below. Colors are a setting, though. StockCharts notes that some charts "use color to show the relationship between the close and the previous close", and CME Group's chart course says the colors vary "depending on the color settings of your software". If two apps paint the same candle differently, check the settings before you trust either one.

Size carries the information. CME Group again: "The longer the body, the more price moved over the time period". A long body means one side controlled the period. A small body, or long wicks on both ends, means neither side could hold its ground. A long upper wick is price that got up there and was sold back down before the close, and a long lower wick is the reverse. Indecision candles show up near turning points and in the middle of dull ranges alike, so on their own they're a reason to look closer and nothing more.

Read candles in sequence. Three green candles with growing bodies show buying that's speeding up. A cluster of small candles after a big move is a pause, and the candle that breaks out of the cluster is the first hint of which side won.

Two more single candles have names worth knowing: the hammer (small body near the top, long lower wick) and the shooting star (small body near the bottom, long upper wick). The candlestick patterns guide covers the multi-candle ones. The method is old. Investopedia's entry says "Candlestick charts originated with Japanese rice merchants in the 18th century".

How Do You Read Trend, Support and Resistance?

Start with direction. In Schwab's definition, stocks making "a series of higher highs and higher lows are considered to be in uptrends". Lower highs and lower lows make a downtrend. Anything else is a range, which traders call chop. Zoom out first, because a downtrend on the daily chart can hold a perfectly nice uptrend on the 5-minute.

A trend line makes that structure visible. Fidelity's trend lesson defines it as "a straight line that connects 2 or more price points", under the lows in an uptrend and over the highs in a downtrend. Investopedia's chart patterns page adds that "Trendlines with three or more points are generally considered more valid". When price breaks the line, Fidelity says it "should serve only as a warning". The trend slowed, and that isn't proof it reversed. The trendline drawing guide covers where to anchor one.

Support and resistance are where the structure pauses. Fidelity's lesson on support and resistance frames them as supply and demand. Support is a level where "demand is strong enough to stop the stock from falling any further", and resistance is where "supply is strong enough to stop the stock from moving higher". A stock that bounces off $25 three times in a month has support at $25, and each hold puts more traders on watch for the next test.

Levels break. A push through resistance is a breakout, a drop through support is a breakdown, and either one means more with volume behind it. Schwab notes that "Breaking support would require high levels of selling volume", and a breakout needs the same from buyers. Broken levels often swap roles. Fidelity: "If the price falls below a support level, that level will become resistance." Old resistance turns into support the same way, and traders who missed the breakout often treat the first pullback to it as a second chance. That pullback is the setup most of my momentum trading strategy is built on.

Treat levels as zones. A $50 level might react anywhere from $49.80 to $50.20. I mark round numbers and the obvious prior highs and lows first. Schwab calls support and resistance "merely psychological levels". They work because enough people watch them. The deep dive on support and resistance levels covers how to draw them.

How Do You Read Volume on a Stock Chart?

The bars under the price panel are volume: how many shares traded during each candle's period. If the bars are new to you, the beginner's guide to stock volume covers what each bar counts and why a red bar isn't selling.

Volume is how you weigh a move. Seeking Alpha's chart guide says moves are "generally seen as more meaningful if they occur on heavy trading volume". A breakout on thin volume is less convincing, and I'd want to see it hold before trusting it. In a healthy uptrend, volume runs heavier on the pushes up and lighter on the pullbacks, which says sellers aren't pressing.

Raw share counts mean little on their own. 5 million shares is huge for a stock that trades 500,000 a day and quiet for one that trades 50 million, so compare volume to the stock's own average. Seeking Alpha uses the average "over the past 20 or 30 trading sessions". Relative volume turns that into a ratio, usually against the stock's normal volume by the same time of day. Even the rough version tells you a lot: 4 million shares by noon on a stock that averages 1 million a day is already 4x a full normal day, with most of the session still to go. Volume also spikes around news and earnings, so check the calendar before you read anything into a spike.

Volume is also liquidity: easier fills and, usually, tighter spreads between the bid and the ask. A source quoted by U.S. News puts it as "you'll have an easier time finding a counterparty to your trade".

Which Indicators Should You Add to a Chart?

Indicators are math on price and volume, so they lag the candles they're built from. Use them as a second opinion on what the candles already say. Of the indicators below, I'd learn moving averages first, because MACD and several others are built on them.

Moving averages (SMA and EMA)

A moving average is the average price of the last N candles, recalculated as each new candle closes. It smooths out the noise. StockCharts' definition is the one to remember: "A moving average doesn't predict price direction. Instead, it defines the current direction." It also "tends to lag because it's based on past prices". A simple moving average weights every candle equally, and StockCharts adds that "exponential moving averages (EMAs) give more weight to recent prices", so an EMA turns sooner.

On daily charts the 50-day and 200-day averages are the common pair. When the 50 crosses above the 200 it's called a golden cross and read as bullish. The reverse is a death cross. Both are slow on purpose, and the golden cross and death cross breakdown covers how far behind price they run.

Intraday, the 9 and 20 EMA are common short settings. A 9 crossing above the 20 says short-term momentum is turning up, and a cross below says it's turning down, though crossovers lag and whipsaw in chop. In a clean trend, price tends to pull back to a rising average and hold it, which is why traders treat moving averages as moving support (or moving resistance in a downtrend). Some traders hold a trend trade while price stays above the 9 EMA and exit on a close below it. The guide to EMA settings for day trading covers the 9 versus the 20.

VWAP (volume-weighted average price)

VWAP is the average price traded so far today, weighted by volume. Investopedia describes it as an indicator "used on intraday charts that resets at the start of every new trading session". StockCharts says it was "developed by institutional investors in order to place large orders without disrupting the market", which is why it doubles as a benchmark for fills. The common reading is that price above VWAP means buyers have had the better of the session, and below it, sellers. Investopedia also notes "it is a lagging indicator and may not predict future price movements". The VWAP trading strategy covers how traders use it intraday.

MACD

MACD tracks the gap between two EMAs. StockCharts' MACD formula: "The MACD line is the 12-day Exponential Moving Average (EMA) less the 26-day EMA." A 9-period EMA of that line is the signal line, and the histogram plots the distance between the two. A cross above the signal line is read as bullish, below as bearish. A growing histogram means momentum is building, and a shrinking one means it's fading, which isn't the same as a reversal. More in the MACD day trading guide.

RSI

RSI measures how fast and how far price has moved, on a scale from 0 to 100. StockCharts: "When the RSI is above 70, it generally indicates overbought conditions", and 30 is the matching oversold line. Those are conventions, and U.S. News cites a caveat about "recognizing that the values of 30 and 70 are arbitrary". RSI can sit above 70 for most of a strong uptrend, so RSI divergence is the more useful read: a new price high with a lower RSI high means the push behind the move is fading.

How many indicators is enough?

Two or three. Every indicator you add is another opinion, and they disagree with each other. Schwab warns that "too many can lead to 'analysis paralysis' where no trading signal is ever given". A setup I'd start with: VWAP, the 9/20 EMA pair and volume. That covers trend, levels and participation without the indicators repeating each other. Nobody needs ten.

What about chart patterns?

Patterns are repeating shapes in the candles, and they split into two families. Continuation patterns are pauses inside a trend that tend to resolve in the trend's direction. Reversal patterns form at the end of a trend. Both are easy to spot after the fact and easy to imagine in real time, so define each one with rules (prior trend, shape, volume) before you go looking.

The chart patterns guide covers each one in depth, and the bull flag breakdown walks through one continuation setup step by step.

What Do the Numbers Above the Chart Mean?

On a quote page the chart sits under a header full of numbers. Most describe today's session and a few describe the company. The table fills them in for XYZ, the made-up stock from the worked example further down.

The change is measured against the previous close, not the open. XYZ closed yesterday at $41.20 and last traded at $43.60, so the header shows +$2.40 (+5.83%). Measured from today's $42.40 open it's up only $1.20. A stock that gapped up and faded all morning can show a big green number over a chart full of red candles.

A stock pressing its 52-week high has no prices above it from the past year, so there's no recent resistance overhead, which is why breakout traders keep a list of them. The spread between the bid and the ask is a cost you pay on every round trip. Two cents on a $43 stock is nothing. Twenty cents on a $3 stock is a big slice of a day trade, and the bid-ask spread explainer has the math.

Regular US trading runs 9:30 a.m. to 4 p.m. Eastern. Premarket trading and after-hours sessions run on thinner volume and wider spreads. Many charting apps let you show or hide those sessions on intraday charts (Robinhood's toggle is labeled "Show all hours"). With them hidden, the premarket high isn't on your chart at all, and it's a level I always mark.

Half of that table is fundamental analysis. Market cap, EPS, P/E and dividend yield describe the business and what you're paying for it. The chart is technical analysis: price and volume, nothing else. Roughly, fundamentals help you decide what to own and charts help you decide when. Schwab's caveat is fair: "Technical analysis is not recommended as a sole means of investment research." On a trade that lasts minutes the chart does most of the work, but an earnings report tonight outranks any indicator on it. Technical vs fundamental analysis covers the split properly.

How Do You Read Charts for Day Trading?

Same skills, faster candles. Investopedia's chart guide says "Day traders look at everything from 1-minute charts to daily charts." The trading itself happens on the 1-, 5- and 15-minute charts, and TradingSim's guide notes that "Many day traders execute on 1- to 5-minute charts". The daily chart is still the first one I open, for context.

Use more than one, top down. The higher timeframe gives you the trend and the levels, and the lower one gives you the entry. Investopedia again: "It's important to look at multiple time frames simultaneously." If the daily is in a downtrend and the 5-minute is bouncing, you're trading a bounce against the bigger trend. That can work, but it deserves a smaller size and a quicker exit. The multi-timeframe analysis routine walks through the top-down order.

Intraday charts add levels a daily chart can't show, like VWAP and the premarket high and low, and yesterday's high and low carry over from the daily. Overnight gaps matter too, since a stock that opens far above yesterday's close starts the day with the whole gap as empty space on the chart. Most of my trades are with-trend momentum: a stock already moving on heavy relative volume pulls back to one of those levels and holds it.

This kind of reading needs volume. On a thin stock the 1-minute candles are mostly wicks, the spread eats the move and levels break for no visible reason. If a stock trades a few thousand shares a minute, I move up a timeframe or move on.

What Order Should You Read a Chart In?

The same order every time, so nothing gets skipped when a stock is moving. Here it is on the XYZ chart from the top of the page: made-up 5-minute candles, 75 minutes into the session, regular hours only, with the premarket high drawn in as a line.

• Step 1
  Timeframe and trend. XYZ closed yesterday at $41.20 and opened at $42.40, a gap up. Since the open it has made a high of $44.05 with higher highs and higher lows along the way. Uptrend.
• Step 2
  Levels. The premarket high at $43.10 capped the first half hour: one candle tagged it exactly and closed back under. The morning high at $44.05 is the next level up.
• Step 3
  Volume. The candle that broke $43.10 traded 3.7x the average of the six candles before it. The four pullback candles each traded less than the one before, from 420K down to 260K shares. The newest candle picked back up to 520K.
• Step 4
  Indicators. The pullback low of $43.15 poked a few cents under VWAP (about $43.23 at the time) and closed back above it, and it held above the old premarket high. Two pullback candles closed just under the 9 EMA. The newest one closed back above it at $43.60, with VWAP near $43.25 and the 9 EMA near $43.42.
• Step 5
  The plan. Read that way, it's a with-trend pullback that held old resistance and VWAP. Now the math. The stop belongs under the pullback low and the premarket high, say $43.05. Buying a break of the newest candle at $43.65 risks $0.60 to make $0.40 to the morning high, about 0.7R. Buying the hold at $43.36 risked $0.31 for $0.69, about 2.2R.

Same chart, very different trades. The read was fine both times and the entry was the problem. If you missed the hold, wait for the next pullback or skip the stock.

A good read still loses sometimes. SoFi's guide says of charts that "they are not a crystal ball", and Investopedia's advice is "don't look at charts in a vacuum", so check the news and the earnings calendar too. Then practice: one market, two or three indicators, the same kind of chart every day until the order is automatic. Investopedia's closing advice is two words, "Start small." One of the best paper trading apps lets you test your reads without paying for the lessons.

What mistakes do beginners make reading charts?

• Clutter
  Five moving averages, RSI, MACD and a cloud on one chart, all waiting to agree with each other. Pick two or three and learn them properly.
• Timeframe
  A stock can look bullish on the 1-minute and bearish on the daily at the same moment. Read the higher timeframe first.
• Bias
  Want a stock to go up and you'll find a bull flag that isn't one. Write down what a valid pattern needs before you open the chart, and skip anything that falls short.
• No plan
  Write down the entry, the stop and the target before you click. If the numbers don't work, the chart doesn't matter.

Where does an AI grade fit?

I build SnapPChart, so I checked this part against its code. You upload one chart screenshot and it grades the setup on that image. It isn't a charting platform, and it doesn't stream prices, connect to a broker or watch the trade after you take it. It reads most of the layers this guide covers, but only what's actually on your image.

So draw what you want read before you take the screenshot. Without VWAP on the chart, the grade says VWAP isn't visible instead of guessing. With extended hours hidden, there's no premarket high to read. The section on what AI can't see on a chart covers the limits of any screenshot read, and the AI chart analysis page covers what this one looks at.

It grades with-trend continuation setups only: a pullback in an established uptrend for a long, or a rally in an established downtrend for a short. Bottom-fishing isn't one of its setups. A chart that's bouncing inside a downtrend gets read as the downtrend it's in, and a long against that trend gets marked down for fighting it. The verdict is enter, wait for a pullback, or skip. When it says enter, the grade can include an entry, a stop and targets. A skip carries no plan at all.

Your first grade is free: a summarized analysis of your chart and a graded second opinion on whether to take it, wait or pass. The summarized analysis is the chart facts it pulled off your image: the trend, the support and resistance levels it marked, and whichever of EMA, VWAP, MACD and volume it could see.

It's most useful once you can read a chart yourself. Then the grade is a second, consistent read of the same screenshot, and it doesn't care how long you've been watching the stock. The XYZ example is exactly when I'd want one, a good-looking chart where chasing the latest candle is the bad part.
