Arc sine function is one of the commonly used inverse trigonometric functions in quantitative trading, used to calculate the angle corresponding to a sine value.
Calculation Principle
Arc sine function is calculated using the following formula:
y = arcsin(x)Where:
- x: Input sine value (range: -1 to 1)
- y: Output angle (in radians, range: -π/2 to π/2)
Parameter Description
- Input Parameters: One K-line data series
- Output: Arc sine value series (in radians)
Usage Recommendations
