Hammer pattern in Japanese candlesticks:

It is a reversal pattern that appears at the end of a downtrend, and indicates the possibility of a reversal towards the upside. It consists of a small body at the top and a long lower shadow, which reflects the market's rejection of low prices and the control of buyers at the end of the session. The pattern is further confirmed by the appearance of a bullish candle after it.
