Line Chart

A line chart connects one price per period — usually the close — into a single line, which makes the overall direction easy to see.

A line chart joins one price per period, usually the close, into a single line. That makes the overall direction easy to see, but it hides the high, low and open. Traders often use line charts for the big picture and switch to bars or candles for detail.

Line charts in plain words

A line chart simply joins each period's closing price with a line.1

It makes the overall direction of price easy to see.1

Unlike bar and candlestick charts, it doesn't show each period's high or low.2

How to read a line chart

  1. Check the price used

    Usually the close.1

  2. Check the timeframe

    Each point is one period.

  3. Read direction

    Look for higher highs and lows, or lower ones.

  4. Mark levels

    Draw support and resistance on turning points.

  5. Remember what is missing

    No high-low range.3

  6. Switch for detail

    Use bars or candles before acting.

Worked examples

Example 1 — Uptrend

Uptrend

Hypothetical closes: 10, 11, 10.5, 12, 11.5, 13.

Example 1 — Uptrend — calculation
Highs11 → 12 → 13

Line charts help visualize the direction of prices; here, higher highs.1

Example 2 — Hidden range

Range hidden

A hypothetical day closes flat but traded 5% up and down.

Example 2 — Hidden range — calculation
Close change0%
Intraday range10%

With no high-low range on a line chart, the intraday swing simply doesn't show.3

Example 3 — Close-only data

Line by default

A hypothetical fund publishes one price a day.

Example 3 — Close-only data — calculation
DataClose only

When a market only has closing prices, a line chart is the natural default.1

Why closes

Beginner

Many traders see the close as the most important price of the day, more than the open, high or low.3

Trade-off

Intermediate

The trade-off is detail: a cleaner chart, but no high-low range.3

Data limits

Advanced

If only end-of-day prices exist for a market, charting tools usually draw a line chart by default.1
