01 — Overview
Go beyond a simple inside-or-outside channel test
The EMA basis anchors inner, outer and extreme ATR bands. ATR-normalized basis slope drives Bias; band location drives Position; recent min–max width rank drives Volatility; distance from the basis drives Stretch.
How it works
EMA slope is normalized by ATR and compared with positive and negative thresholds. Close is classified against each band, while signed basis distance and recent width rank remain separate measures.
ATR-responsive width
The channel expands and contracts with ATR; it is not a fixed-distance envelope.
Tiered location state
Bias and band position classify Inside, Trend Zone, Pullback, Upper/Lower Stretch and Extreme.
Width regime
Width Rank is compared with thresholds for Quiet, Normal and Expanded. It is a recent min–max rank, not a statistical percentile.
02 — Install and start
Add it to TradingView
Add the public script to a chart and identify every drawing in the default configuration first. Change only one input at a time.
Keltner Channel ATR Stretch
Open the public Keltner Channel ATR Stretch page and add it to a TradingView chart. No SG Group account is required.
- Open the “Use on TradingView” link below.
- Select “Use on chart” on TradingView to add the script to your chart.
- Open the gear icon, then Settings → Inputs, and observe the default configuration first.
- Change one input at a time for the symbol and timeframe you are studying.
Prevent misreads when indicators overlap
Overlapping lines, bands, backgrounds or tables can be duplicate drawings of the same kind of information. Never treat visual overlap by itself as stronger evidence or signal agreement. Bollinger Bands, another Keltner channel, VWAP deviation bands and moving averages can place similar bases and envelopes at nearby prices. Isolate the inner, outer and extreme bands before interpreting them.
- Enable Show Basis, Show inner bands, Show outer bands and Show extreme bands one family at a time.
- Do not combine Show channel fills or Tint candles by state with another fill or candle-color study until each source is clear.
- Hide Show dashboard or change Dashboard position when another table uses the same corner.
- Do not count a line overlap with another channel as independent support or resistance confluence.
03 — How to read it
A practical reading order
Do not turn one value or color into a conclusion. Check the condition, persistence and relationship to price in order.
Read Bias as slope
Bullish or Bearish classifies EMA slope, not the direction of the next bar.
Check Position and Stretch
Read band location and basis distance together; an outside print does not guarantee a reversal.
Separate width from direction
Quiet or Expanded describes channel width and does not predict what comes next.
Status and display terms
Bias: Bullish / Bearish / Neutral
A sign classification of ATR-normalized EMA slope, not a price forecast.
Position: Trend Zone / Pullback / Inside
Current location relative to the basis and inner bands, interpreted with Bias.
Upper / Lower Stretch
A distance state between an outer band and the extreme band.
Extreme
Price is beyond the extreme band; no reversal probability is implied.
Quiet / Normal / Expanded
Channel-width classification based on Width Rank.
Width Rank
Current position between the recent minimum and maximum width; not a percentile.

05 — Alerts
Alerts report events, not decisions
Alerts are state, touch or transition events defined in the public source. They are not trade instructions.
- Upper/lower stretch and upper/lower extreme stretch.
- Upper/lower return inside.
- Trend bias changed and Width regime changed.
06 — Limitations and responsible use
Not a buy/sell signal
This tool is for analysis and visualization. It is not investment advice, a trade recommendation, a forecast, or a promise of profit or accuracy. Results depend on inputs, symbol, timeframe, and data feed. You remain responsible for every trading decision.
Outside is not reversal
Stretch and Extreme are distance states. Price can remain outside or continue moving.
ATR moves the bands
Both price and ATR changes affect width and Stretch. Equal readings across symbols or timeframes need not mean equal conditions.
Width Rank definition
It is a recent min–max position, not a statistical percentile, and Quiet does not guarantee a later expansion.
Important
Keep Bias, Position and Volatility as separate axes. Do not convert a band touch by itself into an entry, target or stop.
07 — FAQ
Frequently asked questions
Clarify Bias, Position, Stretch, Width Rank and the meaning of an outside print.
Is Keltner Channel ATR Stretch free to use?
Yes. It is a free, open-source indicator published by SG Group on TradingView. Review TradingView’s terms and the conditions attached to the public script before reuse or redistribution.
Should I change the settings immediately?
Start with the published defaults and observe the drawings and state changes first. Then change one input at a time for the symbol, timeframe and data feed so you can identify what caused each visual change.
Can I display it with other indicators?
Yes, but similar lines, bands, backgrounds and tables can overlap and obscure their source. Isolate each indicator first and hide duplicate components. Visual overlap alone is not stronger evidence or signal agreement.
Does the display provide trade signals?
No. It is analysis and visualization context consistent with the public description. It does not provide entries, exits, targets, stops, price forecasts, or promises of profit, win rate or accuracy.
Is Extreme a contrarian entry signal?
No. Extreme is an ATR-band distance classification. Price can remain outside in a trend, and the label does not instruct a reversal entry, target or stop.
