A stock chart is a record of past prices, drawn so you can see how they moved. It answers three questions: where the price has been, how fast it moved, and how much trading happened along the way. It cannot tell you where the price will go next. Learning to read a chart properly means knowing exactly what each piece shows and what it leaves out.
This guide goes through the parts of a standard chart in the order you should look at them: the time frame, the candles, the volume, and the context around them.
Step 1: choose the time frame
Every chart shows one time frame. Each candle represents a fixed period: one minute, five minutes, one hour, one day, one week. The period you pick decides what you see.
- Intraday charts (minutes or hours) show the moves within one trading session. They are noisy and mostly useful for timing trades within a day.
- Daily charts show one candle per trading day. Most beginners should start here, because each candle covers the whole day's trading.
- Weekly and monthly charts show the longer trend and the big turning points. They move slowly and suit investors who hold for months.
A common habit is to look at a longer time frame first to see the trend, then drop to a shorter one to find the entry. The longer chart tells you which way the wind is blowing. The shorter one tells you when to step out.
Step 2: read a candle
Each candle shows four prices for its period: the open (the first traded price), the high (the highest price), the low (the lowest price) and the close (the last traded price).
A candle has a body and two wicks. The body runs between the open and the close. The wicks, sometimes called shadows, run from the body up to the high and down to the low.
- A green (or white) candle means the close was higher than the open. Buyers were in control for that period.
- A red (or black) candle means the close was lower than the open. Sellers were in control.
The colours depend on the chart settings. Check the legend before you read them.
Long bodies show strong one-sided trading. Short bodies show indecision, where buyers and sellers ended up near where they started. Long upper wicks mean price rose, then sellers pushed it back down. Long lower wicks mean price fell, then buyers pushed it back up.
A single candle means very little on its own. Read a run of candles together to see the direction and the pace of the move.
Step 3: read the volume
Most charts show volume as bars at the bottom. Each bar is the number of shares or units traded in that candle's period. Volume tells you how much conviction sat behind a move.
A price rise on heavy volume means many people agreed with the move. A price rise on light volume is weaker, because fewer traders took part. The same logic works in reverse for falls.
Volume spikes often appear around news, results, index changes and large orders. A spike does not tell you the direction, only that something important happened.
Step 4: find the trend
The trend is the direction the price has been moving over a meaningful period. A simple test: in an uptrend, each peak and each dip is higher than the one before. In a downtrend, each peak and each dip is lower. When neither holds, the price is moving sideways, in a range.
Trend is easier to see on a longer time frame, and it changes. A trend that held for six months can break in a week. The chart shows you when the pattern of highs and lows changes, and that is the signal to re-check your view. The guide on support and resistance covers the levels where trends often pause or reverse.
Step 5: mark the levels that matter
Look for prices the chart has returned to several times. A level where the price stalled or reversed more than once is a level traders remember, and so they often react to it again.
- Support is a price where buying has repeatedly stopped the fall.
- Resistance is a price where selling has repeatedly stopped the rise.
Once price breaks through a level, the old support can become resistance, and the reverse. These levels are useful for planning where you would be wrong, which is where a stop-loss would go. They are not guarantees.
A worked example
Suppose you open a daily chart of a stock. Over three months it has made a series of higher highs and higher lows. That is an uptrend. The most recent candle is a long green body on heavy volume, closing near its high. The price has just broken above a level that stopped the rise twice before.
What does that tell you? The trend is still up. Buyers were in control on the last day. The volume suggests real participation, and the breakout above old resistance is a sign the level may now act as support. None of that guarantees a continued rise. It tells you the chart is currently favouring buyers, and it gives you a level to watch: if the price falls back below the breakout level and stays there, the picture has changed.
Now compare a second stock. Its price rose a similar amount, but on light volume, with long upper wicks that each time rejected the high. The same green candle count looks similar, but the reading is weaker. Sellers are showing up near the top each time.
| What you see | What it suggests | What would change the view |
|---|---|---|
| Higher highs and higher lows | Uptrend | A lower low below the last swing low |
| Long green body on heavy volume | Buyers in control, with participation | A reversal candle on heavy volume |
| Long upper wicks near a high | Sellers pushing the price down | A close above the wick on rising volume |
| Price stuck between two levels | Sideways market | A decisive close beyond either level |
What a chart cannot tell you
A chart shows prices and volume. It does not show the company's profits, its debts, its management, its competitors or the news that is about to come out. A perfect chart can hide a bad business, and a messy chart can sit on top of a good one.
A chart also shows only what traded. It does not show who bought, why, or what they plan to do. Prices can be moved by a few large orders in a thin market, and a clean pattern can appear in a stock that very few people trade.
Common mistakes
Reading too many indicators at once. A chart covered in lines and oscillators is harder to read, not easier. Start with candles, volume and trend. Add an indicator only when you can say what question it answers.
Judging a pattern by one candle. Single candles mislead. Look at the run around them.
Forgetting the scale. On a logarithmic chart, equal vertical distances mean equal percentage moves. On a linear chart they mean equal amounts. Check which one you are looking at before you compare two stocks.
Choosing the time frame after you see the result. If you keep switching time frames until the picture looks right, you are fitting the chart to your view, not reading it.
Checklist for reading any chart
- Name the time frame, and check a longer one for the trend.
- Read the last five to ten candles: their bodies, wicks and colours.
- Compare the volume on the moves with the volume on the quiet days.
- Mark the two or three levels the price has respected.
- Write down what would prove you wrong.
- Check the news and the date of the next result before you act.
Key takeaways
A chart is a summary of past trading. Candles show how each period went, volume shows how much conviction sat behind it, and the trend shows the direction over time. Read those three together on a time frame that matches how long you plan to hold. Mark the levels, write down what would change your view, and check the news. A chart tells you what has happened and what the market is currently doing. It does not tell you what happens next.
