This is my first attempt on plotting harmonic patterns based on zigzag. Initial version is still primitive and might need lot of time to mature into more formidable one. Will try to explain entire logic in the description. Please feel free to correct me if my understanding of any pattern and underlying logic is incorrect.
In the initial version,
Only immediate high lows of pivots are considered for calculation of patterns.
In case of ABCD Types, only one is shown at a time. Hence, disabling certain ABCD pattern types may result in different numbers.
Logic for double top/bottom is taken from previous script - Double top/bottom Ultimate. Though logic of confirmation and invalidation is not included
All other patterns which involve 4+ lines can coexist and often shown together.
Smaller timeframes may give error due to some pine limitations.
Error percent parameter is used for allowing minor deviation from the standard ratios.
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
Release Notes

Removed deviation threshold and disable stats on load. (Can be enabled in settings)
Hi, great work!
PLS let me know the reason of "Too many drawings, cannot clean oldest."
I have 4 chart on trading view (10m, 15m, 30m, 1 hour).
On 10m , it works very well. but the others show me that massage( Too many drawings, cannot clean oldest.)
Thanks!

@Machine425, Hey, please try multi zigzag harmonic pattern and multi level zigzag harmonic patterns script.
Number of lines issue is common in lower timeframes for scripts which draws too many lines and labels.

hi Awesome work, have search for serveral scripts like this and yours is the best. Is there a way to make alerts when a pattern is ploted?
