```talib.OBV()```函数的返回值为：一维数组。
array

talib.OBV(inReal)
talib.OBV(inReal, inPriceV)

```inReal```参数用于指定K线数据。
inReal
true
{@struct/Record Record}结构数组、数值数组
```inPriceV```参数用于指定K线数据。
inPriceV
false
{@struct/Record Record}结构数组

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

import talib
def main():
    records = exchange.GetRecords()
    ret = talib.OBV(records.Close, records.Volume)
    Log(ret)

void main() {
    auto records = exchange.GetRecords();
