Std.dev [AY¹] - Extended Range Deviation Indicator
This indicator calculates and displays standard deviation levels based on a custom session's high and low range, with lines extending until the next session start.
Key Features:
Custom Session Definition: Set your preferred session time (default: 09:00-11:30)
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
Session Visualization: Optional session range boxes and vertical start/end lines
Equilibrium Line: Optional mid-point line between session high and low
How it Works:
Identifies the specified session period each day
Captures the highest and lowest prices during that session
Calculates the range (high - low)
Draws multiple deviation levels above and below the range
Extends all levels until the next session begins
Use Cases:
Support and resistance level identification
Price target projections
Range-based trading strategies
Market structure analysis
Settings:
Session time configuration
Number of deviation levels (1-10)
Line styles and colors
Show/hide session boxes and labels
Customizable anchor points (wicks vs bodies)
The indicator preserves historical levels, allowing traders to analyze multiple sessions simultaneously for comprehensive market structure analysis.
