OPEN-SOURCE SCRIPT
Mis à jour 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:
ABCD Classic
AB=CD
ABCD Extension
Gartley
Crab
Deep Crab
Bat
Butterfly
Shark
Cypher
Three Drives
5-0
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:

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

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

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