Examples


    javascript
    
    
function main() {
    var records = exchange.GetRecords()
    var ret = talib.SAREXT(records)
    Log(ret)
}


    python
    
    
import talib
def main():
    records = exchange.GetRecords()
    ret = talib.SAREXT(records.High, records.Low)
    Log(ret)


    c++
    
    
void main() {
    auto records = exchange.GetRecords();
    auto ret = talib.SAREXT(records);
    Log(ret);
}

Returns

Type	Description
array	The `talib.SAREXT()` function returns a one-dimensional array.

Arguments

Name	Type	Required	Description
inPriceHL	`Record` structure array	Yes	The `inPriceHL` parameter is used to specify K-line data.
optInStartValue	number	No	The `optInStartValue` parameter is used to set the Start Value, default value is 0.
optInOffsetOnReverse	number	No	The `optInOffsetOnReverse` parameter is used to set the Offset on Reverse, default value is 0.
optInAccelerationInitLong	number	No	The `optInAccelerationInitLong` parameter is used to set the long initial acceleration factor (AF Init Long), default value is 0.02.
optInAccelerationLong	number	No	The `optInAccelerationLong` parameter is used to set the long acceleration factor (AF Long), default value is 0.02.
optInAccelerationMaxLong	number	No	The `optInAccelerationMaxLong` parameter is used to set the long maximum acceleration factor (AF Max Long), default value is 0.2.
optInAccelerationInitShort	number	No	The `optInAccelerationInitShort` parameter is used to set the short initial acceleration factor (AF Init Short), default value is 0.02.
optInAccelerationShort	number	No	The `optInAccelerationShort` parameter is used to set the short acceleration factor (AF Short), default value is 0.02.
optInAccelerationMaxShort	number	No	The `optInAccelerationMaxShort` parameter is used to set the short maximum acceleration factor (AF Max Short), default value is 0.2.

Remarks

The SAREXT() function is described in the talib library documentation as: SAREXT(Records[High,Low],Start Value = 0,Offset on Reverse = 0,AF Init Long = 0.02,AF Long = 0.02,AF Max Long = 0.2,AF Init Short = 0.02,AF Short = 0.02,AF Max Short = 0.2) = Array(outReal)
