Also referred to as a "trend reversal", "rally" or "correction".



A reversal can be a positive or negative change against the prevailing trend. Technical analysts watch for these patterns because they can indicate the need for a different trading strategy on the same security.

For example, if a technical analyst holds stock ABC and notices a reversal pattern, he or she may want to consider closing his or her existing long position and assuming a short position to capitalize on the potential downward movement of the stock's price.
