Library "Obj_XABCD_Harmonic"
Harmonic XABCD Pattern object and associated methods. Easily validate, draw, and get information about harmonic patterns. See example code at the end of the script for details.
init_params(pct_error, pct_asym, types, w_e, w_p, w_d)
Create a harmonic parameters object (used by xabcd_harmonic object for pattern validation and scoring).
Parameters:
pct_error: Allowed % error of leg retracement ratio versus the defined harmonic ratio
pct_asym: Allowed leg length/period asymmetry % (a leg is considered invalid if it is this % longer or shorter than the average length of the other legs)
types: Array of pattern types to validate (1=Gartley, 2=Bat, 3=Butterfly, 4=Crab, 5=Shark, 6=Cypher)
w_e: Weight of ratio % error (used in score calculation, dft = 1)
w_p: Weight of PRZ confluence (used in score calculation, dft = 1)
w_d: Weight of Point D / PRZ confluence (used in score calculation, dft = 1)
Returns: harmonic_params object instance. It is recommended to store and reuse this object for multiple xabcd_harmonic objects rather than creating new params objects unnecessarily.
init(xX, xY, aX, aY, bX, bY, cX, cY, dX, dY, params, tp, p)
Initialize an xabcd_harmonic object instance.
If the pattern is valid, an xabcd_harmonic object instance is returned. If you want to specify your
own validation and scoring parameters, you can do so by passing a harmonic_params object (params).
Or, if you prefer to do your own validation, you can explicitly pass the harmonic pattern type (tp)
and validation will be skipped. You can also pass in an existing xabcd_harmonic instance if you wish
to re-initialize it (e.g. for re-validation and/or re-scoring).
Parameters:
xX: Point X bar index
xY: Point X price/level
aX: Point A bar index
aY: Point A price/level
bX: Point B bar index
bY: Point B price/level
cX: Point C bar index
cY: Point C price/level
dX: Point D bar index
dY: Point D price/level
params: harmonic_params used to validate and score the pattern. Validation will be skipped if a type (tp) is explicitly passed in.
tp: Pattern type
p: xabcd_harmonic object instance to initialize (optional, for re-validation/re-scoring)
Returns: xabcd_harmonic object instance if a valid harmonic, else na

get_symbol(p)

get_pid(p)
Get the Pattern ID. Patterns of the same type with the same coordinates will have the same Pattern ID.
Parameters:

set_target(p, target, target_lvl, calc_target)
Set value for a target. Use the calc_target parameter to automatically calculate the target for a specific harmonic ratio.

Harmonic XABCD Pattern object and associated methods. Easily validate, draw, and get information about harmonic patterns. See example code at the end of the script for details.
init_params(pct_error, pct_asym, types, w_e, w_p, w_d)
Create a harmonic parameters object (used by xabcd_harmonic object for pattern validation and scoring).
Parameters:
pct_error: Allowed % error of leg retracement ratio versus the defined harmonic ratio
pct_asym: Allowed leg length/period asymmetry % (a leg is considered invalid if it is this % longer or shorter than the average length of the other legs)
types: Array of pattern types to validate (1=Gartley, 2=Bat, 3=Butterfly, 4=Crab, 5=Shark, 6=Cypher)
w_e: Weight of ratio % error (used in score calculation, dft = 1)
w_p: Weight of PRZ confluence (used in score calculation, dft = 1)
w_d: Weight of Point D / PRZ confluence (used in score calculation, dft = 1)
Returns: harmonic_params object instance. It is recommended to store and reuse this object for multiple xabcd_harmonic objects rather than creating new params objects unnecessarily.

v6Updated to use point, leg, and pattern objects.
Updated:
init(pattern, params, tp, p)
Initialize an xabcd_harmonic object instance from a given pattern

and validation will be skipped. You can also pass in an existing xabcd_harmonic instance if you wish
to re-initialize it (e.g. for re-validation and/or re-scoring).
Parameters:
pattern: Pattern
params: harmonic_params used to validate and score the pattern. Validation will be skipped if a type (tp) is explicitly passed in.
tp: Pattern type
p: xabcd_harmonic object instance to initialize (optional, for re-validation/re-scoring)
