Extended Lines: Deviation lines extend from session end until next day's session start (09:00)
Flexible Deviation Types: Choose between full deviations (1.0, 2.0, 3.0...) or half deviations (0.5, 1.0, 1.5, 2.0...)
Visual Differentiation: Half deviation levels are displayed with dashed lines for easy identification
Anchor Point Options: Calculate deviations based on wicks or candle bodies
