Candlesticks themselves show four points of price movement within a defined time period. They show opening price, closing price, and the highs and lows of the price. The candlestick is made up of a wide part (known as the “real body”) that displays the open price and the close price as well as two thinner components on either end of the real body known as the “wicks.” These represent the high price and the low price. For example, if the upper wick of a candle is short, it indicates the opening price was near to the high price of the defined time-frame.
We don't know everything about the markets. We're just devoted to learners. Taken from those smarter than ourselves, here's how we define Candlesticks.
