Top 4 Single Candlestick Patterns Hammer A hammer pattern is one of the most effective, yet least understood candlestick formations. It is a very good indication that the current downtrend is losing its momentum and that a reversal is very close on the horizon. The hammer, as it is commonly known, is one of the most powerful bullish signals, and that's why it's also one of the most common patterns used by currency traders. There are several different types of hammers, but they all have one thing in common: the long black body of the candle is followed by a short, or sometimes even non-existent, trading period, during which the price moves sharply higher.
Key points about Hammer 1. The hammer should form at the bottom of a downtrend. 2. The shadows are several times longer than the original body. 3. The upper shadows are almost nonexistent. 4. The colour of the candle is not important, whether red or green.
