A point on a candle stick chart representing a specific time period (a day, an hour, a minute, etc) in which the underlying stock price has moved. Candlesticks will have a body and usually two wicks – one on each end. For a white (could also be green) candlestick, the bottom of the body represents the opening price and the top of the body represents the closing price. For red candlesticks, it is just the other way around. The top and bottom tips of each wick are the day’s highest and lowest price respectively.
You do not need anything else on a stock chart but the candles themselves to be a successful swing trader! And, there is nothing that can improve your trading more than learning the art of reading candlestick charts
