Aggiornato Session Seed Range (LON / FRA / NY / CME / ASIA + 3 Custom) — v6

Session Seed Range → Lines (LON / FRA / NY / CME / ASIA + 3 Custom)
What it does
This tool draws two horizontal levels—the High and Low of a short seed window at each market open (e.g., London 09:00–09:05)—and extends them to the session close (e.g., 17:30). An optional Mid line (average of seed High/Low) can be displayed as well.
Included sessions
• London, Frankfurt, New York, CME, Asia
• Plus 3 fully custom sessions (name, seed window, session end)
Key features
• Seed window → extended lines: Capture the initial opening move and project it across the trading session.
• Timezone dropdown: Choose from common IANA timezones (incl. Europe/Istanbul)—no manual offset math.
• Label language: DE / EN / TR (or Off) for price labels at the right edge.
• Show/Hide Mid line per your preference.
• 3 custom sessions: Add your own schedules with custom names.
• Per-session styling: Colors and widths for High/Low/Mid.
• Lightweight: Works on any timeframe.
________________________________________
Quick start
1. Pick your Timezone in the Inputs.
2. Enable a session (e.g., London) and set its Seed (HHMM–HHMM) and Session End (HHMM).
3. Optionally turn on Show mid line and Labels (DE/EN/TR).
4. Repeat for other sessions or use the Custom A/B/C blocks.
Tip: The seed window must be visible on the chart’s timeframe so the High/Low can be collected. If you don’t see lines, zoom in or use a lower timeframe.
________________________________________
Inputs overview
• Timezone: IANA timezone selection.
• Labels: Off / DE / EN / TR + label offset (ticks).

• Session blocks (London, Frankfurt, New York, CME, Asia, Custom A/B/C):

________________________________________
Notes & limitations
• Lines are built from the seed window only; they do not repaint once the seed completes.
• If the chart timeframe is too high to include the seed window, switch to a lower TF or widen the seed.
• This indicator is for analysis/education only and not financial advice.

Note di rilascio
v1.0.1 — Range Source Selector (Wicks / Bodies)Added
• New input “Range source” (Inputs → Options):
Wicks (High/Low) or Bodies (Body High/Low).
o Bodies uses max(open, close) and min(open, close) for the seed window.
• The chosen source drives High, Low, and the optional Mid line.
Behavior & compatibility
• Default = Wicks (High/Low) to preserve v1.0.0 results.
• Applies globally to all sessions (London / Frankfurt / New York / CME / Asia / Custom A–C).
• No change to existing settings; simply pick your preferred source if needed.
Notes
• If your chart uses synthetic bars (e.g., Heikin Ashi), the body/wick definitions follow the displayed series.
• Ensure the seed window is visible on your timeframe to capture values.
