Related to come under the hammer: hammered out
In candlestick charts, the representation of a trading day where a security trades significantly below its opening price for most of the day, but closes either above or close to the opening price. It is called a hammer because the candlestick representing the trading day looks somewhat like a hammer. It is not necessarily a bullish indicator, but a hammer may mean that the market is nearing a bottom.
