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: [patternArray, patternLabelArray] 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: [patternArray, patternLabelArray] 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: [dStart, dEnd] 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: [dStart, dEnd] Start and end of consolidated PRZ range

@navrang081, it’s not an indicator. It’s library for developers.

Thank you for your help Float x = 316.53 Float a = 327.91 Float b = 322.22 Float c = 326.36 I type xABC and get index 24 (patternLabelArray, "Total"). Does Total mean that all patterns can occur?

errorPercent = input.int(8, group="Miscellaneous") float x=370.32 float a=383.2 float b=373.67 float c=380.09 patterns =s.isHarmonicProjection(x,a,b,c,flags, errorPercent = errorPercent) ------------------ Thanks for your library, I have A problem with the above code, I want to type X A B C, call isHarmonicProjection, the result shows Syntax error at input 'int'. May I ask what the reason is? My intention is to enter the XABC indicator and predict point D.
@HeWhoMustNotBeNamed, Thank you very much for your reply. I have defined it ----------------- flags = array.new_bool() array.push(flags, enableGartley) array.push(flags, enableCrab) array.push(flags, enableDeepCrab) array.push(flags, enableBat) array.push(flags, enableButterfly) array.push(flags, enableShark) array.push(flags, enableCypher) array.push(flags, enableNenStar)
@HeWhoMustNotBeNamed, Thank you very much for your answer, which is very helpful for novices. Another problem that has been bothering me for a long time is that I want to display the return value in the table,----------------------- string s=array.get(patterns,0) table.cell(tab1, 0, 1, s , text_halign = text.align_left, text_size= size.normal, text_color=color.white) -------- Declared type string is not compatible with assigned type series bool

@lzhqlj5406207, you need to convert that bool to string. If patterns(0) is true, Gartley, pattern(1) is true, Crab etc.
