The goal of investors who want to use this technical analysis algorithm is to try to make a profit by taking advantage of the price fluctuations and oscillations of a market. In a downtrend, each bottom is lower than the previous low. If there is a trough higher than the last trough formed by such oscillations in a falling trend and the subsequent trend is in the upward direction, this is explained as a "Failure Swing" in a falling trend.
