Hammer Candlestick Pattern Definition
If there was a large drop in price in the middle of the day, but before the day ended it increased to what it was at the beginning of the day and even more, a significant upward return occurred. The candlestick of this change (move) will be a "Hammer" in a daily time frame. A Hammer formation on the daily time frame is a very strong indication for a high probability of increasing price in the next few days.
