```TA.KDJ()```函数的返回值为二维数组，结构为：```[K, D, J]```。
array
TA.KDJ(inReal)
TA.KDJ(inReal, period, kPeriod, dPeriod)
```inReal```参数用于指定K线数据。
inReal
true
{@struct/Record Record}结构数组、数值数组
```period```参数用于设置周期1。
period
false
number
```kPeriod```参数用于设置周期2。
kPeriod
false
number
```dPeriod```参数用于设置周期3。
dPeriod
false
number
```javascript
function main(){
var records = exchange.GetRecords(PERIOD_M15)
var kdj = TA.KDJ(records, 9, 3, 3)
Log("k:", kdj[0], "d:", kdj[1], "j:", kdj[2])
}
def main():
r = exchange.GetRecords(PERIOD_M15)
kdj = TA.KDJ(r, 9, 3, 3)
Log("k:", kdj[0], "d:", kdj[1], "j:", kdj[2])
void main() {
auto r = exchange.GetRecords();
auto kdj = TA.KDJ(r, 9, 3, 3);
Log("k:", kdj[0], "d:", kdj[1], "j:", kdj[2]);
}
测试TA.KDJ()函数：
TA.KDJ()函数的period、kPeriod、dPeriod参数的默认值为：9、3、3。
