Calculates the Alligator indicator.


    
    
    
TA.Alligator(inPriceHL)


    
    
    
TA.Alligator(inPriceHL, jawLength, teethLength, lipsLength)

Examples

Compute the jaw, teeth and lips lines of the Alligator with default parameters.


    javascript
    
    
function main() {
    var records = exchange.GetRecords()
    if (!records) return
    var alligator = TA.Alligator(records)
    Log("jawLine:", alligator[0])
    Log("teethLine:", alligator[1])
    Log("lipsLine:", alligator[2])
    // Output: three arrays that are 8, 5 and 3 elements longer than the K-lines (padded with NaN at
    // the start)
}


    python
    
    
def main():
    records = exchange.GetRecords()
    if not records:
        return
    alligator = TA.Alligator(records)
    Log("jawLine:", alligator[0])
    Log("teethLine:", alligator[1])
    Log("lipsLine:", alligator[2])
    # Output: three lists that are 8, 5 and 3 elements longer than the K-lines (padded with None at
    # the start)


    rust
    
    
fn main() {
    let Ok(records) = exchange.GetRecords(None, None, None) else { return };
    let alligator = TA.Alligator(&records, None, None, None);
    Log!("jawLine:", alligator[0]);
    Log!("teethLine:", alligator[1]);
    Log!("lipsLine:", alligator[2]);
    // Output: three arrays that are 8, 5 and 3 elements longer than the K-lines (padded with NaN at
    // the start)
}

Returns

Type	Description
array	The return value of the `TA.Alligator()` function is a two-dimensional array with the structure: `[jawLine, teethLine, lipsLine]`. The jaw, teeth and lips lines are shifted right by 8, 5 and 3 bars: 8, 5 and 3 `NaN` (`None` in `Python`) are prepended respectively, so the three arrays are 8, 5 and 3 elements longer than the input.

Arguments

Name	Type	Required	Description
inPriceHL	`Record` array	Yes	K-line data (the median of the high and low prices is used). Only K-line data is accepted.
jawLength	number	No	Period of the Jaw line.
teethLength	number	No	Period of the Teeth line.
lipsLength	number	No	Period of the Lips line.
