Editing ALGORITHM II

 '''The N1 rule (N1 requirement) for Algorithm II is as follows:'''
  If point 3 is low, then the level of point 5 should be higher than point 1. 
  If point 1 is high, then the level of point 5 should be lower than point 1.

==='''STEP I. SEARCH FOR POINT 3 OF THE EXTERNAL ATTRACTION MODEL (EAM) AND THE STARTING POINT OF THE PREVIOUS TREND.'''===

: '''1.1.''' The program looks for the first possible extreme, satisfying rule N1. Such an extreme is a candidate for potential point 3 ( potential t.3).

: '''1.2.''' Next, the program checks the bars from right to left (i.e., in the past) from the bar containing the extreme candidate for point 3 to one of the following events:

:: '''1.2.1.'''Found the last intersection (breakthrough) point by the price level of the candidate for point 3.
::In this case, the report displays: :: PREVdata FullDataPrev :: The program proceeds to substep 1.3.
:: '''1.2.2.'''The program reached the starting point of the chart (i.e., the price did not intersect the level of point 3 after the starting point of the chart).
::In this case, the report displays: :: PREVdata NoFullDataPrev :: The program proceeds to substep 1.3.
:: '''1.2.1.'''The price checked 300 bars preceding point 3, but the level of step 3 did not intersect at this segment. The program looks for an absolute extreme (opposite to step 3) on the segment from the 300th bar before point 3 to point 3. The program proceeds to substep 1.3.

: '''1.3.'''The program looks for an absolute extreme (opposite to point 3) on the segment:
::- from the last intersection by the price level of the candidate for point 3 (inclusive) (if coming from 1.2.1.), or :: - from the starting point of the chart (if coming from 1.2.2.), or :: - from 300 bars to point 3 (if coming from 1.2.3.) :: to point 3 (excluding).
:: '''1.3.1.'''Absolute extreme found. The candidate for point 3 is confirmed; moreover, the found confirming extreme is the assumed (if coming from 1.2.2. or 1.2.3.) starting point of the preceding trend.'''
::The program checks for the absence of extremes equal to point 3 between the assumed starting point of the previous trend and point 3. 
:::'''1.3.1.1.''' If such an extreme is found, this candidate for point 3 is discarded, and this point 3 is discarded. 
:::'''1.3.1.2.''' If such an extreme is not found, the program proceeds to step 2.
::'''1.3.2.'''Absolute extreme not found. This point 3 is discarded.'''
::Simultaneously with step 1, the program launches the search for the next potential point 3.
