In a chart, especially in financial markets, a "candle" (short for candlestick) represents price movement over a specific period of time — such as 1 minute, 1 hour, 1 day, etc.

Each candlestick shows four main pieces of information:

1. Open price – The price at the beginning of the time period.

2. Close price – The price at the end of the time period.

3. High price – The highest price during the period.

4. Low price – The lowest price during the period.

Anatomy of a Candlestick:

If the close price is higher than the open, the candle is usually green or white – meaning bullish (price went up).

If the close price is lower than the open, the candle is usually red or black – meaning bearish (price went down).

Candlestick charts are widely used in technical analysis to identify patterns and trends in stocks, forex, crypto, and other markets.
