Traditional Keltner Channels use small ATR multipliers that often fail during extended trends or sudden volatility surges. By aligning your channel with Laws 1–3—using an EMA(200) midline and ±15×ATR(200) bands—you create a robust “trend tube” that defines valid higher highs/lows and automates trailing stops in one cohesive envelope.

Summary

• Midline = EMA(200), bands = ± 15 × ATR(200)
• Trend-tube rules for higher high/higher low validation
• Automated trailing via dynamic channel updates

1. Pine/MT4 Code Snippet

Below is an example in Pine Script for TradingView:

// Keltner Channel with k = √200 exposures  
emaMid = ta.ema(close, 200)  
atr200 = ta.atr(200)  
k = math.round(math.sqrt(200))   // k = 15  
upper = emaMid + k * atr200  
lower = emaMid - k * atr200  

plot(emaMid, color=color.blue)  
plot(upper, color=color.green, style=plot.style_linebr)  
plot(lower, color=color.red, style=plot.style_linebr)  

Adapt similarly in MT4/5 using iMA and iATR functions.

2. Trend Failure & Acceleration Signals

• Trend Validity: All higher lows must remain above the lower band, and higher highs should occur within or above the upper band.
• Trend Failure: A close below the lower band signals a structural break—exit long positions.
• Trend Acceleration: A breakout above the upper band in strong momentum often marks the start of an extension phase—consider scaling in.

3. Chart Gallery Across Assets

Here are examples of the k=15 Keltner Channel applied to different instruments:

• Gold (XAU/USD) Daily chart
• EUR/USD 4H chart
• WTI Oil 1H chart

All show consistent trend-tube validation and automated trailing in action.

4. Entry, Re-Entry & Exit Rules

4.1 Entry Signals

• Pullback Entry: Wait for a dip that holds above the lower band (EMA(200)−15×ATR(200)), then enter long on a close back above the midline (EMA(200)).
  Rationale: You’re buying in the lower 0.44 % tail of volatility (Chebyshev), with trend confirmed by the EMA.
• Breakout Entry: If price has already cleared the upper band (EMA(200)+15×ATR(200)) in strong momentum, enter on a pullback that stays above the upper band.
  Rationale: Captures trend‐extension moves—only accelerate when price returns from a new alligator swing high.

4.2 Re-Entry / Scaling-In

• Midline Retest: After a first‐leg move above upper band, you can scale in on a shallow pullback to EMA(200) or into the channel’s midpoint buffer (≈ EMA + 7–8×ATR).
  Rule of Thumb: Only re-enter if price stays above the previous swing low and the lower band.
• Band‐Bounce: On a second clear touch of the upper band—without closing below midline—you may add to your position, keeping each lot’s stop at its own lower‐band level.

4.3 Exit Rules

• Trend Break Exit: Close the full position if price closes below the lower band. This indicates a structural trend failure beyond the 99.56 % noise tube.
• Midline Exit (Optional): In choppy or sideway regimes (flat channel), you can exit half your size when price closes below EMA(200), preserving capital for clearer setups.
• Time‐Stop: If no meaningful band‐touch or trend extension occurs within 2–3×ATR(200) worth of bars, manually exit to avoid low‐probability drift.

4.4 Example Workflow

1. Plot EMA(200) & ±15×ATR(200) bands.
2. Wait for a pullback above the lower band.
3. Enter when price closes back above EMA(200).
4. Shift stop to breakeven when price gains ≥ L×ATR(200) (per Laws 4–5).
5. Scale in further on midline or upper-band retests (per 4.2).
6. Exit fully on a close below the lower band.

This sequence ensures you’re always trading within the 15×ATR “trend tube,” only entering into confirmed structure, locking in profits at breakeven, and exiting on true structural breaks.
