get_gator(quotes: Iterable[Quote])

get_gator(quotes: Iterable[AlligatorResult])

Parameters

name	type	notes
`quotes`	Iterable[Quote] or Iterable[AlligatorResult]	Iterable(such as list or an object having `__iter__()`) of the Quote or Alligator Result.

Historical quotes requirements

If using default settings, you must have at least 121 periods of quotes. Since this uses a smoothing technique, we recommend you use at least 271 data points prior to the intended usage date for better precision. If using a custom Alligator configuration, see Alligator documentation for historical quotes requirements.

quotes is an Iterable[Quote] or Iterable[AlligatorResult] collection of historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Return

GatorResults[GatorResult]

This method returns a time series of all available indicator values for the quotes provided.
GatorResults is just a list of GatorResult.
It always returns the same number of elements as there are in the historical quotes.
It does not return a single incremental indicator value.
The first 10-20 periods will have None values since there’s not enough data to calculate.

Convergence warning: The first 150 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.

GatorResult

name	type	notes
`date`	datetime	Date
`upper`	float, Optional	Absolute value of Alligator `Jaw-Teeth`
`lower`	float, Optional	Absolute value of Alligator `Lips-Teeth`
`is_upper_expanding`	bool, Optional	Upper value is growing
`is_lower_expanding`	bool, Optional	Lower value is growing
