A candlestick is a type of price chart used in technical analysis that displays the high, low, open, and closing prices of an asset for a specific period. The wide part of the candlestick is called the "body" and tells traders whether the closing price was higher or lower than the opening price (red if the closing price was lower than the open one, green if the closing price was higher).
An asset's price fluctuations are measured with four main metrics: “open,” “high,” “low” and “close”.
“Open” and “close” metrics display the asset price at the beginning and the end of a selected time period; “high” and “low” metrics show the maximum and the minimum price of the asset during the period.
Please look at the candlesticks:
the ends of the wick are the highs and the lows
the body of the candle is formed by the opening and the closing prices
Green candles mean a net gain, while red candles show a net loss.
