Round-Level Zones — Auto NQ/GC Support & Resistance Map

This indicator automatically maps out horizontal reaction zones around round-number price levels for Nasdaq (NQ/MNQ) and Gold (GC/MGC) futures, adjusting its logic to match the instrument you're viewing.

How it works

The script detects the symbol you're on and applies the appropriate round-level structure:

  • NQ / MNQ → zones are drawn from xx80 to xx20 around each round hundred (e.g. a zone at the 24,000 level runs from 24,020 down to 23,980)
  • GC / MGC → zones are drawn from xx8 to xx2 around each round ten (e.g. a zone at 3350 runs from 3352 down to 3348)


Zones re-center automatically as price moves, giving you a consistent, always-current map of nearby round-number levels without manually drawing lines on each instrument.

Features

  • Works on both NQ/MNQ and GC/MGC — no separate indicators or settings to switch
  • Adjustable number of zones displayed above/below price (1–50)
  • Customizable zone fill color, border line color, style (solid/dashed/dotted), and width
  • Optional price labels on each zone boundary
  • Adjustable right-side offset and left-extension of lines
  • On-chart warning if applied to an unsupported symbol


Why round numbers matter

Round price levels tend to attract order flow — stops, limit orders, and psychological decision points cluster around them. Having these zones pre-mapped can help with spotting potential reaction areas, planning entries/exits, or keeping round-number context visible without cluttering the chart with manual drawings.

Usage notes

Designed specifically for the round-number structures of NQ/MNQ (hundreds) and GC/MGC (tens). This is a visual reference tool only and does not generate buy/sell signals — always combine with your own strategy, market structure analysis, and risk management.
