I have marked all the hammer patterns visible in the chart prior to trend revarsal.the same was created on friday...
HAMMERS and HANGING-MAN
Recognition: The lower shadow (or tail) should be at least two times the length of the body. The color of the body is not important although a black body has slightly more Bearish indications and a white body has slightly more Bullish indications.
Pattern Psychology: This pattern at the bottom of a down trend is called a Hammer. This pattern at the top of an uptrend is called a Hanging-Man
It is a revarsal indication .
