The candlestick chart was invented in Japan to record the price movement of rice. A single candle gives us four market data for a particular point of time that is open, High, low, close and the colour of the candle show us whether the market is making a loss, i.e. Bearish or red candle or gain, i.e. bullish or green candle at that particular time.
Candlestick pattern is a method used by a technical analyst to anticipate movement in the market. The candlestick patterns are formed by one candle or by groping more the one candles in a particular sequence. However, multiple candlestick patterns are more reliable than a single candlestick pattern.
