Syntax

talib.SAR

Calculates the Parabolic SAR.


    
    
    
talib.SAR(inPriceHL)


    
    
    
talib.SAR(inPriceHL, optInAcceleration)


    
    
    
talib.SAR(inPriceHL, optInAcceleration, optInMaximum)

Examples

Compute the Parabolic SAR from the latest K-lines.

javascript
python


    javascript
    
    
function main() {
    var records = exchange.GetRecords()
    if (!records) return
    var ret = talib.SAR(records)
    Log(ret)
}


    python
    
    
import talib
def main():
    records = exchange.GetRecords()
    if not records:
        return
    ret = talib.SAR(records.High, records.Low)
    Log(ret)

Returns

Type	Description
numeric array	Indicator values, the same length as the input; the leading values without enough data are `NaN`.

Arguments

Name	Type	Required	Description
inPriceHL	`Record` array	Yes	K-line array; the high and low fields are used. In Python, pass `records.High`, `records.Low` in this order.
optInAcceleration	number	No	Acceleration factor. Default `0.02`.
optInMaximum	number	No	Maximum acceleration factor (AF Maximum). Default `0.2`.
