Struct ADX

pub struct ADX { /* private fields */ }

Average Directional Index (ADX) Indicator

ADX measures trend strength regardless of direction. It’s composed of:

• True Range (TR): Max of (H-L), (H-Cp), (Cp-L)
• Directional Movement: +DM = H-Hp (if positive), -DM = Lp-L (if positive)
• Directional Indicators: +DI = (+DM smoothed / TR smoothed) * 100
• Directional Index: DX = (|+DI - -DI| / (+DI + -DI)) * 100
• ADX = Smoothed average of DX values

ADX interpretation:

• 0-25: Weak trend or ranging market
• 25-50: Strong trend
• 50+: Very strong trend
