SPY ATR Bands

303
An all-in-one overlay that combines ATR-based deviation bands, all-time-high levels, and a weekly-EMA trend filter into a single clean tool. Built for swing dip-buying on SPY, but works on any symbol.

Features

• Multi-timeframe ATR bands (D / 4H / 1H) — Keltner-family bands built from an RMA centerline ± ATR × multiplier, with three depths each (narrow ×0.6 / main / wide ×1.5). Because they scale with ATR, a touch of the wide band means a statistically significant move relative to current volatility, not a fixed %. Lines are smoothed between higher-TF updates. Color-coded by TF (D / 4H / 1H), with optional narrow/wide layers.

• Intersection markers — A bubble is dropped at the deepest band touched within each incursion (narrow > main > wide), per timeframe. Instantly shows where price is interacting with each TF's volatility envelope.

• ATH line + pullback levels — Running all-time-high line plus −3 / −4 / −5 / −10 / −15 / −20 / −25% pullback levels (labels only). The ATH label shows price, days since the last ATH, and current trend-leg %. A live "Now" label shows price and exact % distance from the ATH (candle-colored).

• W EMA20 proxy (trend filter) — Approximates the weekly EMA20 on any timeframe (1H/Daily proxies, down to intraday) so you always see the higher-TF trend line. The line turns green when the last daily candle closes above it and red when it closes below — a clean bull/bear read. Includes a tolerance zone, an intersection marker, and an optional interpolation mode for a smooth line down to 5-minute charts.

• Built-in alerts — "Any intersection marker", "Lower-band touch (dip)", and "W EMA20 touch".

How to use

Watch for price tapping a lower band (oversold) while well below the ATH and above the W EMA20 line (trend intact). The deeper the band and the further from the ATH, the higher-conviction the pullback. The W EMA20 color tells you whether the broader regime is bullish or bearish.

Most colors, widths, tolerances and toggles are fully configurable in settings.
