Japanese candlestick charts have appeared for over 100 years and are one of the most popular types of cryptocurrency charts. This type of chart illustrates price movements over a specific time period.

Each "candle" represents the opening, closing, high, and low prices of a cryptocurrency like Bitcoin during the specified time frame.

The "body" of the candle represents the range between the opening and closing prices of the cryptocurrencies, while the "wick" shows the highest and lowest levels reached.

In candlestick charts, full and defined candles indicate different market sentiments.
