Dealing Range Auto-Zone v2.1

เมื่อวานซืน

Dealing Range Auto-Zone v2.1 - Summary
Purpose: Automatically creates zone-based support/resistance levels within a dealing range using percentage-based spacing with ATR-driven recommendations.
How It Works:

Click two points to define dealing range (high and low)
Set step % (e.g., 0.25% = one zone every 0.25% move)
Indicator calculates exact zone count and draws upper/lower zone boundaries
Optional center lines show midpoint of each zone

Key Features:

Zone-based S/R - Upper and lower boundaries instead of single lines (creates "price zones" rather than precise levels)
Auto-calculated spacing - Uses exact % steps with math.round() for optimal coverage (minimizes gaps near boundaries)
Adjustable zone width - Default 50% of step (e.g., 0.25% step = 0.125% zone width on each side)
Ghost zones - Extends zones above/below range for anticipating breakouts
ATR-based recommendations - Calculates Daily ATR and suggests Tight/Balanced/Wide step % based on current volatility
Smart validation - Compares your step % to ATR recommendations and shows if it's appropriate for current market conditions

Use Case:
Converts dealing ranges into tradeable S/R zones for 15s-5m intraday scalping. Makes it clear when price is "in a zone" vs "at a precise line." Ideal for MNQ, MGC, and other liquid futures/crypto.

Version 2.1 Changes:
New Features:

Daily ATR calculation with automatic Tight/Balanced/Wide step % recommendations
Volatility-based auto-recommendations (compares ATR(14) vs ATR(50))
Smart validation system that evaluates your step % choice and provides feedback
Info table shows all three ATR recommendations (Tight/Balanced/Wide)

Improvements:

Changed from math.floor() to math.round() for zone count calculation (eliminates gaps near boundaries)
Streamlined info table (removed redundant rows: Range points, Step %, Total Lines)
Added color-coded validation (green checkmark for appropriate settings, orange warning for extreme values)

Bug Fixes:

Fixed tooltip compilation error (moved dynamic ATR data to info table only)
Corrected validation logic to properly categorize step % ranges

Info Table Now Shows:

Range % (dealing range size as %)
Exact Zones (calculated, including fractional)
Zones Drawn (rounded to nearest whole number)
Zone Width (in price points and % of step)
Daily ATR (value and %)
Auto Rec (all three recommendations: T/B/W)
Your Step (with validation: ✓ Tight/Balanced/Wide or ⚠️ Very Tight/Wide)
