==='''Step I. Find Point 1. Search for a Confirming Extreme.'''===
: '''1.1.''' The program searches for the first possible extreme that satisfies Single Bar Rule. This extreme is a candidate for point 1.
: '''1.2.''' When a candidate for point 1 (hereinafter referred to as t.1 candifate) is found, all bars to the left (i.e., in the past) of the bar containing the t.1 candidate extreme are checked until one of the following events occurs:
:: '''1.2.1.''' The place of the last intersection of the price level of the  t.1 candidate is found <ref>High or low equal to high or low of t.1 is an intersection</ref>. In this case, the program searches for an absolute extreme that confirms point 1 from the intersection of the price with the t.1 candidate level (inclusive) to the bar of t.1 candidate (exclusive). There are two possibilities:
::: '''1.2.1.1.''' If the extreme is not found, the program searches for a new candidate for point 1.
::: '''1.2.1.2.''' If the absolute extreme is found, it is the beginning of the preceding trend. The point 1 is confirmed. 
::: The program checks for the absence of extremes equal to point 1 from the Beginning of the preceding trend. 
:::: '''1.2.1.2.1.''' If such an extreme is found, this candidate for point 1 is discarded (the program continues to process other t.1 candidates).
:::: '''1.2.1.2.2.''' If such an extreme is not found, the program proceeds to process the next bar after point 1 according to point 2 of the Algorithm.
:: '''1.2.2.''' The program has reached the starting point of the chart (i.e., after the starting point of the chart, the levels of points 1 and 2 have never intersected). The program searches for a confirming extreme from right to left to the starting point of the chart. The options are similar to the sub-steps 1.2.1.1. and 1.2.1.2.
:: '''1.2.3.''' The program has checked 50 bars <ref>The depth of the search for the extreme confirming point 1</ref> preceding the bar of the potential point 1, and none of the above events have occurred. The program searches for a confirming extreme from right to left in the area of 50 bars before the potential point 1. The options are similar to the sub-steps 1.2.1.1. and 1.2.1.2.
