In finance, there exists a method known as the median line technique, which is utilized by technicians to determine pivotal points in the market. This involves selecting an extreme low or high and drawing a line, called the median line, that divides the next corrective phase. Parallel lines are then drawn through the high and low points, creating a price channel that defines both resistance and support levels. This technique allows for a deeper understanding of market trends and can assist in making informed decisions regarding investments.
