Asian Range + CE Deviations

Asian Range + CE Deviations

Marks the Asian session range each day, its midpoint (Consequent Encroachment), and standard-deviation projections of the range.

WHAT IT PLOTS
- Asia High and Asia Low: the highest and lowest price traded between 20:00 and 02:00 New York time.
- CE (Consequent Encroachment): the 50% midpoint of the range.
- Deviations: projections measured from a leg anchored at the range high (1) to the CE (0).
Price = CE + k × (High − CE)
Default levels: −2, −2.5 (below the range) and +2, +2.5 (above the range).
Each leg is half the range, so ±2 sits half a range beyond the high/low and ±2.5 sits three-quarters of a range beyond.

HOW IT WORKS
- The high, low and CE update live while the Asian session is forming.
- Deviation levels are added once the session closes at 02:00, when the range is final.
- Each day's levels extend until the next Asian session begins.
- Previous days stay on the chart (20 by default, up to 90).

SETTINGS
- Session time and timezone (default 20:00–02:00 America/New_York)
- Number of days to display
- Four editable deviation values
- Separate colour, width and line style for the range, CE and deviations
- Label toggle, size and background transparency

NOTES
- Use on intraday timeframes of 1 hour or lower so the session boundaries align with bars.
- Works on any instrument; session times can be changed to suit other markets.
