Candlesticks are graphical representations used in financial markets to display price movements of assets over a specific time period. Each candlestick consists of a body and two wicks, showing the opening and closing prices, as well as the highest and lowest prices during that time frame. The body is filled or hollow, indicating whether the price increased or decreased. Traders often use candlestick patterns to analyze market trends and make informed decisions. Common patterns include doji, hammer, and engulfing, each providing insights into potential future price movements. Understanding these patterns can help traders identify buying or selling opportunities.
