Hyperbolic Tangent Function

The hyperbolic tangent function is one of the commonly used hyperbolic functions in quantitative trading, used to calculate the hyperbolic tangent value.

Calculation Principle

The hyperbolic tangent function is calculated using the following formula:

y = tanh(x) = (e^x - e^(-x)) / (e^x + e^(-x))

Where:

• x: Input value (range: -∞ to +∞)
• y: Hyperbolic tangent value (range: -1 to 1)

Parameter Description

• Input Parameters: One K-line data series
• Output: Series of hyperbolic tangent values

Usage Recommendations

1. Pay attention to input value range
2. Consider numerical precision
3. Pay attention to result interpretation
4. Consider saturation characteristics
5. Pay attention to boundary value handling
6. Consider practical application scenarios
