Standard Deviation (Basic) — Patch Notes

What’s new
• Two custom sessions (A & B) only—no presets.
• Timezone-aware sessions (IANA, e.g., America/New_York, Europe/London).
• Exact width matching: SD lines span exactly from the session’s first bar to its last bar
(same as the box).
• Start/End verticals control: None, Start only, End only, or Both.
• Anchor choice: Build ranges from either Wicks or Bodies.
• Deviation style: Full (1.0× steps) or Half (0.5× steps), with adjustable count.
• Optional Equilibrium (midline).
• Global line style and box visibility toggles.

How it works (under the hood)

1. Session tracking:
• At each session start (based on your Session + Timezone) the script stores the start bar and initializes hi/lo.
• While the session is active, it updates hi/lo using Wicks or Bodies (your choice) and extends the box to the current bar.
• On session end, it records the end bar.

2. Deviation drawing:
• Computes range = high − low.
• Draws symmetric SD bands above/below using your Full/Half setting and count.
• All SD lines are drawn from start bar → end bar so they match the box width exactly.
• If Equilibrium is on, the midline (avg of high/low) is drawn across the same width.

3. Start/End lines:
• According to Start/End Lines setting, verticals are drawn at the start bar, end bar, both, or not at all—each spanning from session low to high.

Quick use
• Pick Session windows for A/B and set each Timezone.
• Choose Wicks or Bodies, Full/Half deviations, Count, Color, and whether to show

Equilibrium and Boxes.
• Set Start/End Lines to control the vertical markers.
• Optional: change Line Style (solid/dotted/dashed).
