eHarmonicpatternsExtended

Trendoscope Wizard Updated   
Library "eHarmonicpatternsExtended"
Library provides an alternative method to scan harmonic patterns. This is helpful in reducing iterations. Republishing as new library instead of existing eHarmonicpatterns because I need that copy for existing scripts.

scan_xab(bcdRatio, err_min, err_max, patternArray) Checks if bcd ratio is in range of any harmonic pattern
  Parameters:
    bcdRatio: AB/XA ratio
    err_min: minimum error threshold
    err_max: maximum error threshold
    patternArray: Array containing pattern check flags. Checks are made only if flags are true. Upon check flgs are overwritten.

scan_abc_axc(abcRatio, axcRatio, err_min, err_max, patternArray) Checks if abc or axc ratio is in range of any harmonic pattern
  Parameters:
    abcRatio: BC/AB ratio
    axcRatio: XC/AX ratio
    err_min: minimum error threshold
    err_max: maximum error threshold
    patternArray: Array containing pattern check flags. Checks are made only if flags are true. Upon check flgs are overwritten.

scan_bcd(bcdRatio, err_min, err_max, patternArray) Checks if bcd ratio is in range of any harmonic pattern
  Parameters:
    bcdRatio: CD/BC ratio
    err_min: minimum error threshold
    err_max: maximum error threshold
    patternArray: Array containing pattern check flags. Checks are made only if flags are true. Upon check flgs are overwritten.

scan_xad_xcd(xadRatio, xcdRatio, err_min, err_max, patternArray) Checks if xad or xcd ratio is in range of any harmonic pattern
  Parameters:
    xadRatio: AD/XA ratio
    xcdRatio: CD/XC ratio
    err_min: minimum error threshold
    err_max: maximum error threshold
    patternArray: Array containing pattern check flags. Checks are made only if flags are true. Upon check flgs are overwritten.

isHarmonicPattern(x, a, b, c, d, flags, errorPercent) Checks for harmonic patterns
  Parameters:
    x: X coordinate value
    a: A coordinate value
    b: B coordinate value
    c: C coordinate value
    d: D coordinate value
    flags: flags to check patterns. Send empty array to enable all
    errorPercent: Error threshold
  Returns: Array of boolean values which says whether valid pattern exist and array of corresponding pattern names

isHarmonicProjection(x, a, b, c, flags, errorPercent) Checks for harmonic pattern projection
  Parameters:
    x: X coordinate value
    a: A coordinate value
    b: B coordinate value
    c: C coordinate value
    flags: flags to check patterns. Send empty array to enable all
    errorPercent: Error threshold
  Returns: Array of boolean values which says whether valid pattern exist and array of corresponding pattern names.

get_prz_range(x, a, b, c, patternArray, errorPercent, start_adj, end_adj) Provides PRZ range based on BCD and XAD ranges
  Parameters:
    x: X coordinate value
    a: A coordinate value
    b: B coordinate value
    c: C coordinate value
    patternArray: Pattern flags for which PRZ range needs to be calculated
    errorPercent: Error threshold
    start_adj: - Adjustments for entry levels
    end_adj: - Adjustments for stop levels
  Returns: Start and end of consolidated PRZ range

get_prz_range_xad(x, a, b, c, patternArray, errorPercent, start_adj, end_adj) Provides PRZ range based on XAD range only
  Parameters:
    x: X coordinate value
    a: A coordinate value
    b: B coordinate value
    c: C coordinate value
    patternArray: Pattern flags for which PRZ range needs to be calculated
    errorPercent: Error threshold
    start_adj: - Adjustments for entry levels
    end_adj: - Adjustments for stop levels
  Returns: Start and end of consolidated PRZ range
Release Notes:
v2

Added:
getSupportedPatterns(patternLabelArray) Returns the list of supported patterns in order

get_projection_range(x, a, b, c, patternArray, errorPercent, start_adj, end_adj) Provides Projection range based on BCD and XAD ranges

Release Notes:
v6

Minor logical updates
