Auto Harmonic PatternsThis 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

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

Adaptive Donchian ChannelThis is Slight modified version of Donchian channel. Only change here is, channels update only when there is breakout. If price keeps ranging within channel, it will not contract based on new highest and lowest range.
This can be used for identifying powerful breakouts post long consolidation and filter out fakeouts.
