confirmation and only has a long lower shadow limitations of using hammer candlesticksthere is no assurance that the price will continue to move to the upside following the confirmation candle a long shadowed hammer and a strong confirmation candle may push the price quite high within two periods this may not be an ideal spot to buy as the stop loss may be a great distance away from the entry point exposing the trader to risk that doesn t justify the potential reward hammers also don t provide a price target so figuring what the reward potential for a hammer trade is can be difficult exits need to be based on other types of candlestick patterns or analysis psychology of the hammeras we have seen an actionable hammer pattern generally emerges in the context of a downtrend or when the chart is showing a sequence of lower highs and lower lows the appearance of the hammer suggests that more bullish investors are taking positions in the stock and that a reversal in the downward price movement may be imminent the long lower shadow on the hammer candlestick indicates an effort to continue the price s downward trajectory but the higher close represented by the real body indicates that the sellers were ultimately unsuccessful in holding the price at its intraday low the price s ascent from its session low to a higher close suggests that a more bullish outlook won the day setting the stage for a potential reversal to the upside practical applicationif you ve spotted a hammer candlestick on a price chart you may be eager to make a trade and profit from the potential upcoming price movement before you place your order let s take a look at a few practical considerations that can help you make the most of a trade based on the hammer pattern the first step is to ensure that what you re seeing on the candlestick chart does in fact correspond with a hammer pattern if you re looking for hammer signal that implies a potential upside reversal it should occur in the context of a downtrend or declining price action marked by a series of lower highs and lower lows under these circumstances the signal you re keeping an eye out for is a hammer shaped candlestick with a lower shadow that is at least twice the size of the real body the closing price may be slightly above or below the opening price although the close should be near the open meaning that the candlestick s real body remains small confirmation of a hammer signal occurs when subsequent price action corroborates the expectation of a trend reversal in other words the candlestick following the hammer signal should confirm the upward price move traders who are hoping to profit from a hammer signal often buy during the formation of this upward confirmation candle as with any trade it is advisable to use stops to protect your position in case the hammer signal does not play out in the way that you expect the level at which you set your stop will depend on your confidence in the trade and your risk tolerance however it may be useful to set a stop loss below the low of the hammer pattern providing protection in case the downward pressure reemerges and the upward move that you were anticipating never materializes on the other hand if the price does begin to rise rewarding your recognition of the hammer signal you will have to decide on an optimal level to exit the trade and take your profits on its own the hammer signal provides little guidance as to where you should set your take profit order as you strategize on a potential exit point you may want to look for other resistance levels such as nearby swing lows
