The hammer is equally as easy to see. Think of it as the opposite of a shooting
star. So it has to be at the bottom of a downtrend. It has a small body with wicks
below the body of the candle that are at least 2-3 times the size of the candle
body. It signals the reversal of a downtrend. The huge wicks make it eye catchy
as well. See the chart below which also happens to show a shooting star also.
