chart for Gator Oscillator

// C# usage syntax
IEnumerable<GatorResult> results =
  quotes.GetGator();

// with custom Alligator configuration
IEnumerable<GatorResult> results = quotes
  .GetAlligator([see Alligator docs])
  .GetGator();

Historical quotes requirements

If using default settings, you must have at least 121 periods of quotes to cover the warmup and convergence periods. 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 a collection of generic TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.

Response

IEnumerable<GatorResult>

This method returns a time series of all available indicator values for the quotes provided.
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 null 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

Date DateTime - Date from evaluated TQuote

Upper double - Absolute value of Alligator Jaw-Teeth

Lower double - Absolute value of Alligator Lips-Teeth

UpperIsExpanding bool - Upper value is growing

LowerIsExpanding bool - Lower value is growing

Chaining

This indicator may be generated from any chain-enabled indicator or method.

// example
var results = quotes
    .Use(CandlePart.HLC3)
    .GetGator();

Results cannot be further chained with additional transforms.
