Understand Daily ATR & SDTR Context on SPX

WHY

Every trader needs clarity.

Markets move quickly, volatility shifts without warning, and daily price action often feels chaotic unless you understand the context behind it.

When you know where you are inside the day’s expected range and volatility environment, decision-making becomes more objective, disciplined, and confident.

That’s the purpose of this tool:
to give traders a clearer sense of intraday reality so they can act with intention instead of impulse.

HOW

It does this by anchoring each session to a set of objective, volatility-based reference points:

• Daily ATR projections that outline the day’s typical movement range
• A standardized deviation envelope (SDTR) that highlights areas of expansion or exhaustion
• RTH-aligned resets, so the levels refresh cleanly at the start of each session

These elements work together to form a steady, unbiased framework around each trading day.

WHAT

The result is a daily ATR + SDTR context overlay, now available free on TradingView.

It provides:
• Expected daily high/low zones based on smoothed ATR
• A volatility shell around the prior close
• Daily context levels that reset automatically at each RTH open
• A clean, unobtrusive visual guide for interpreting intraday price behavior

It works on any intraday timeframe and integrates seamlessly with your existing workflow — structure, VWAP, volume analysis, price action, Fibonacci levels, or your preferred set of signals.

This isn’t a trading system.
It’s a lens — designed to help traders see the day more clearly.
