What is a line chart in trading?
In one line: A line chart is a price chart that joins each closing price with a single line, showing the overall direction but not the highs, lows or opens.
A simple example
Here are 5 daily closes for a stock:
| Day | Close |
|---|---|
| Mon | $20 |
| Tue | $21 |
| Wed | $20.50 |
| Thu | $22 |
| Fri | $23 |
A line chart puts a dot at each close and joins them. You see a line going up with one small dip on Wednesday.
What you don't see: on Wednesday the stock may have fallen to $18.90 before bouncing back. Only a Candlestick or Bar chart (OHLC) shows that.
What it does well
A line chart is the cleanest way to see the big picture. It cuts the noise down to one line.
That's why news sites and long-term charts use it. It's also a handy way to spot where price turned around on a big Timeframe. The peaks and dips of the line are often clearer than on a busy candle chart.
Why it matters
Closes matter more than the wiggles in between. Many traders say the close is the price where buyers and sellers "agreed" for that period.
Our method uses the same idea in a different form: only a candle body closing past a level counts, not a Wick poking through. A line chart is built only from those closes.
A common mistake
Setting a stop from a line chart. The line skips the highs and lows. A Stop loss placed just past a dip on the line could sit right where price went many times. You need the full range to see that.
Try this on TradingView: switch a daily chart to a line chart, mark the clear peaks and dips, then switch back to candles. You'll see the same turning points, plus the wicks around them.

It's good for seeing direction and big turning points. For planning entries and stops, most traders switch to candles or bars, which show highs and lows.
What price does a line chart use?
Usually the close of each period. Some platforms let you pick the open, high, low or an average instead.
What is the difference between a line chart and a candlestick chart?
