talib

swordfish.function.talib()

Regarding null value handling, the differences between DolphinDB’s built-in moving functions and Python TA-lib lie in:

• DolphinDB moving functions: The calculation in the sliding window starts from the first element.

• Python TA-lib: Keep the null values at the beginning of data in the output. The calculation in the sliding window starts from the first non-null value.

Parameters:

func (Constant) – A function.
