Arccos Function

The arccos function is one of the commonly used inverse trigonometric functions in quantitative trading, used to calculate the angle corresponding to a cosine value.

Calculation Principle

The arccos function is calculated using the following formula:

y = arccos(x)

Where:

• x: Input value (range: -1 to 1)
• y: Angle value (range: 0 to π, unit: radians)

Parameter Description

• Input Parameters: One K-line data series
• Output: Series of angle values (radians)

Usage Recommendations

1. Pay attention to input value range (must be between -1 and 1)
2. Consider the unit of result (radians)
3. Pay attention to numerical precision
4. Consider result interpretation
5. Pay attention to boundary value handling
6. Consider practical application scenarios

Notes

• Ensure data quality
• Pay attention to data preprocessing
• Consider the impact of extreme values
• Pay attention to numerical range limitations
• Consider result stability
• Pay attention to computational efficiency
• Pay attention to practical application scenarios
• Pay attention to boundary value handling
• Consider result interpretation
