Candlestick Chart

Configurable options for the candlestick chart.

A candlestick chart is a type of chart commonly used in financial markets and stock trading. It uses a series of candlestick-shaped figures to display the opening, high, low, and closing prices. Candlestick charts are especially suitable for displaying time-series data, particularly in financial markets, such as stock, futures, and forex price movements.

Suitable scenarios include:

  1. Financial Market Analysis: Candlestick charts allow you to observe the opening, closing, highest, and lowest prices, helping to analyze market trends.
  2. Trend Analysis: Candlestick charts help determine the market's trend direction (uptrend, downtrend, or consolidation) and market sentiment (bullish or bearish). The patterns and shapes of the candlesticks can provide signals for trend reversal or continuation.
  3. Support and Resistance: Candlestick charts can help identify key support and resistance levels, which are crucial for investment decisions.
  4. Pattern Recognition: Candlestick charts can reveal classic candlestick patterns that are used to predict future price movements.

Each candlestick includes four main elements:

  • Open: The lower end (for uptrend) or the upper end (for downtrend) of the candlestick body, representing the price at the beginning of a given time period.
  • Close: The upper end (for uptrend) or the lower end (for downtrend) of the candlestick body, representing the price at the end of the time period.
  • High: The upper end of the candlestick's wick, representing the highest price within the time period.
  • Low: The lower end of the candlestick's wick, representing the lowest price within the time period.
