Line, Bar & Candlestick Charts
Three ways to draw the same prices, and why candles became the trader’s default.
A price chart can be drawn several ways, and each shows a different amount of information about the same underlying prices. The three you’ll meet constantly are the line chart, the bar chart and the candlestick chartA chart bar showing a period’s open, high, low and close..
- Line chart — connects just the closing prices into a single line. Simplest and cleanest; great for spotting the overall trendThe prevailing direction of price: up, down or sideways., but it hides the action within each period.
- Bar chart (OHLC) — each period is a vertical bar showing Open, High, Low and Close. Far more information than a line, but visually harder to scan quickly.
- Candlestick chartA chart bar showing a period’s open, high, low and close. — same OHLC data as a bar, but drawn as a “candleA chart bar showing a period’s open, high, low and close.” with a coloured body. Instantly shows who won the period at a glance.
All three plot the same prices — the difference is how much of the story each reveals and how fast your eye can read it. Candlesticks won because they encode the full Open-High-Low-Close and make the buyer-vs-seller battle visually obvious through the body’s size and colour. Your brain reads a wall of candles far faster than a wall of bars — which is why traders default to them.
ExampleOn a line chart a day just shows “closed at ₹500.” The candleA chart bar showing a period’s open, high, low and close. for that same day might reveal it opened at ₹480, spiked to ₹510, crashed to ₹475, then closed at ₹500 — a violent, indecisive day the line completely hid. Same close, very different story.
Key takeawayLine, bar and candlestickA chart bar showing a period’s open, high, low and close. charts plot the same prices with increasing detail. Candlesticks show full OHLC and make the period’s buyer/seller battle instantly visible — which is why they’re the trader’s default.
