SVE Daily ATR + SDTR Context Bands

SVE Daily ATR + SDTR Context Bands is a free companion overlay from The Volatility Engine™ ecosystem.

It plots daily ATR-based expansion levels and a Standardized Deviation Threshold Range (SDTR) to give traders a clean, quantitative view of where intraday price sits relative to typical daily movement and volatility extremes.

This module is designed as an SVE-compatible context layer—using discrete, RTH-aligned daily zones, expected-move bands, and a standardized volatility shell—so traders can build situational awareness even without the full SPX Volatility Engine™ (SVE).

It does not generate trade signals.
Its sole purpose is to provide a clear volatility framework you can combine with your own structure, Fibonacci, or signal logic (including SVE, if you use it).

🔍 What It Shows

* Daily ATR Bands (expHigh / expLow)

- Expected high/low based on smoothed daily ATR

- Updates at the RTH open

* Daily SDTR Bands (expHighSDTR / expLowSDTR)

- Standard deviation threshold range for volatility extremes

- Helps identify overextended conditions

Discrete RTH-aligned Zones

- Bands reset cleanly at each RTH session

No continuous carry-over from prior days

🎯 Purpose

This tool helps traders:

- Gauge intraday context relative to expected daily movement

- Assess volatility state (quiet, normal, expanded, extreme)

- Identify likely exhaustion or expansion zones

- Frame intraday price action inside daily volatility rails

- Support decision-making with objective context rather than emotion

It complements any strategy and works on any intraday timeframe.
