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

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

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

SAREXT()函数在talib库文档中的描述为：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)
