Candlestick
Price bar showing open, high, low, and close, used to read short-term price behavior and chart context.
A candlestick is one price bar that shows an asset’s open, high, low, and close for a chosen period.
In plain language, it is a compact visual summary of what happened during that period: where price started, where it ended, and how far it traveled in between.
Why a Candlestick Matters
A single candlestick can reveal:
-
whether buyers or sellers controlled the period
-
whether the move ended near the highs or lows
-
whether price was rejected at one end of the range
-
how strong or weak the period looked relative to nearby candles
That makes candlesticks useful building blocks for chart reading, even though one candle alone is not a full trading system.
How It Works in Finance Practice
Each candlestick contains four data points:
The body shows the distance between the open and close. The shadows, or wicks, show the full intraperiod range.
In practice, traders rarely read a candle in isolation. They combine candle structure with:
-
surrounding candles
-
trend direction
Practical Example
Suppose one daily candle has:
-
open at
50 -
high at
55 -
low at
49 -
close at
54
That candle has a bullish body because the close is above the open. It also shows that buyers finished the day near the top of the range. If the same candle appears after a long decline and near support, traders may read it differently than if it appears in the middle of a noisy sideways market.
Candlestick vs. candlestick chart
A candlestick is one bar. A candlestick chart is a sequence of many candles across time.
That distinction matters because the meaning of one candle often depends on the candles around it.
A long wick does not guarantee reversal
It may show rejection, but traders still need context and confirmation.
Candlesticks are not only for stocks
They are used across equities, futures, currencies, crypto, and other traded markets.
