The INFINITI APRO indicator displays the lows and highs of the price on the chart, as well as the places of the trend change and divorces (double trend change or more). The algorithm for determining extrema is based on the assertion that the price goes at least two pulses ("GROWTH-ROLL-GROWTH" or "REDUCTION-ROLL-REDUCTION"). Thus, the search for minima and maxima is based on a thorough analysis of each candle and their combination. The trend change is sought according to the standard technical analysis algorithm - the interruption of the highs in a downtrend from the downtrend to the upward trend, the interruption of the minimum in the upward trend means a change of trend from upward to downward.
