Arc Sine Function

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

1. Pay attention to input value range
2. Consider angle unit (radians)
3. Pay attention to numerical precision
4. Consider periodic characteristics
5. Pay attention to result interpretation

Notes

• Ensure data quality
• Pay attention to data preprocessing
• Consider the impact of extreme values
• Pay attention to numerical range
• Consider periodicity
• Pay attention to result stability
• Consider computational efficiency
• Pay attention to practical application scenarios
