Auto Harmonic Patterns - Open Source

I may not be able to spend much time on the harmonic patterns and realized that there are not much open source scripts on them either. Hence, decided to release open source version which can be used by other developers for reference and build things on top of it.

Original script is protected and can be found here:

Logical ratios of patterns are coded as below:

Notations:

• Lines XABCD forms the pattern in all cases. (OXABCD in case of Three drives )
  
• abc = BC retacement of AB, xab = AB retracement of XA and so on
  

ABCD Classic

• 0.618 <= abc <= 0.786
  
• 1.272 <= bcd <= 1.618
  

AB=CD

• Price difference between AB and CD are equal
  
• Time difference between AB and CD are equal
  

ABCD Extension

• 0.618 <= abc <= 0.786
  
• 1.272 <= AD/ BC (price) <= 1.618
  

Gartley

• xab = 0.618
  
• 0.382 <= abc <= 0.886
  
• 1.272 <= bcd <= 1.618 OR xad = 0.786
  

Crab

• 0.382 <= xab <= 0.618
  
• 0.382 <= abc <= 0.886
  
• 2.24 <= bcd <= 3.618 OR xad = 1.618
  

Deep Crab

• xab = 0.886
  
• 0.382 <= abc <= 0.886
  
• 2.0 <= bcd <= 3.618 OR xad = 1.618
  

Bat

• 0.382 <= xab <= 0.50
  
• 0.382 <= abc <= 0.886
  
• 1.618 <= bcd <= 2.618 OR xad = 0.886
  

Butterfly

• xab = 0.786
  
• 0.382 <= abc <= 0.886
  
• 1.618 <= bcd <= 2.618 OR 1.272 <= xad <= 2.618
  

Shark

• xab = 0.786
  
• 1.13 <= abc <= 1.618
  
• 1.618 <= bcd <= 2.24 OR 0.886 <= xad <= 1.13
  

Cypher

• 0.382 <= xab <= 0.618
  
• 1.13 <= abc <= 1.414
  
• 1.272 <= bcd <= 2.0 OR xad = 0.786
  

Three Drives

• oxa = 0.618
  
• 1.27 <= xab <= 1.618
  
• abc = 0.618
  
• 1.27 <= bcd <= 1.618
  

5-0

• 1.13 <= xab <= 1.618
  
• 1.618 <= abc <= 2.24
  
• bcd = 0.5
  

This script contains everything which original script has apart from stats. Use the original script if you are not developer looking for code reference and prefer having stats table.

I have also developed a strategy based on harmonic patterns which can be found here:

版本注释:

• Removed deviation threshold and disable stats on load. (Can be enabled in settings)
  
• Default length is set to 5
  

版本注释:

Update labels

版本注释:

update labels

版本注释:

Fix error

版本注释:

Remove stats again

版本注释:

Corrected errors in 3-Drive and 5-0 where B does not need to be in the middle.

版本注释:

Minor parameter adjustments.

版本注释:

Add labels.

版本注释:

Minor correction in zigzag calculation logic.

Also, check my other script on harmonic pattern (Again - open source)

版本注释:

No updates. But, just converted to pine 5 :)
