As the candle is lit, the shadows cast by the candlestick demonstrate how the day's highs and lows relate to the start and end of the day. A candlestick's shape is influenced by connections between the day's high, low, and opening/closing prices, among other factors. Technical analysts use candlesticks to determine when to enter and exit positions based on investor sentiment. Candlestick charting was inspired by a Japanese rice-price-monitoring method developed in the late 1800s. Candlesticks can be used to trade any liquid financial asset, such as stocks, foreign currency, and futures.

A candlestick is a visual tool that helps traders understand how prices change over time. Each candlestick reflects one trading period and includes four important prices: the open, high, low, and close. The thick body shows the distance between the opening and closing prices, while the thin wicks represent the highest and lowest prices reached during the session. When the close is above the open, the candle is bullish, indicating buying activity. When the close is below the open, it is bearish, showing selling pressure. Candlestick charts make it easier to spot trends and shifts in market sentiment compared to basic price charts. Traders often study well-known candlestick formations to predict whether prices may continue in the same direction or reverse. Learning these fundamentals provides a strong starting point for beginners who want to understand technical analysis and improve their trading skills.
