MM8 Best Regression Channel

MM8 Best Regression Channel — Smart regression channel with auto-optimized length and density histogram
\Summary\
This indicator automatically searches the optimal regression length (optimalLength) between 50 and 200 (step 5) and draws a channel whose effective width is minimized. It then overlays a color-gradient regression channel plus a compact, right-edge density histogram to show where price spends most of its time inside the channel. The goal is to blend mean-reversion context with breakout assessment in a clean, visual way.
\How it works\
1. Length optimization: For each candidate length (50…200, step 5) the script computes variance of the source and its linear correlation with time (bar\_index). Residual volatility (MAD proxy) is estimated via sqrt(v − v\*r^2). The channel width is evaluated as 2×MAD with an internal optimizer multiplier (mult\_opt = 2.0). The length that yields the smallest effective width is selected as optimalLength.
2. Regression and channel: Using optimalLength, the slope (alpha) and intercept (beta) are derived from source vs. bar\_index. Upper/lower channel boundaries are set at ±MAD scaled by the user “Multiplier”.
3. Density histogram: The channel span is split into N bins. For each bin, the script counts how many of the last optimalLength bars fall inside that band and draws a short horizontal tick on the right edge. Longer ticks imply higher dwell time.
\Inputs\
* Bins Number: number of histogram bands (default 7).
* Multiplier: scales the final channel width used for drawing (separate from mult\_opt used only in the optimizer).
* Source: input data (default Close).
* Style → Show Histogram: toggle the right-edge density ticks.
* Style → Channel Color (Lower/Upper): colors for the channel gradient (from lower to upper).
* Style → Histogram Bins Color: color for the right-edge ticks.
* Style → Line Style: channel line style (solid / dashed / dotted).
\What you see\
* A regression channel rendered with a lower→upper color gradient.
* A right-edge horizontal histogram for each band; tick length encodes the count of bars residing in that band over the last optimalLength window.
* To reduce overhead, lines are deleted/rebuilt and the drawing routine executes on the last bar (barstate.islast).
\Interpretation and use\
* Mean reversion: Touches or brief pierces of outer bands with low local density can suggest short-term fade setups.
* Breakout context: A sustained push with rising density near a boundary, backed by structure and volume, can support continuation.
* Multiplier tuning: Smaller → tighter/more sensitive channel; larger → smoother/less noisy.
* Bins tuning: More bins give finer distribution detail (at the cost of a busier plot).
\Practical notes\
* On noisier symbols/timeframes, consider a larger Multiplier.
* If the right-edge histogram looks too crowded, reduce Bins or increase Multiplier.
* Combine with market structure (HH/HL/LH/LL), volume, and supply/demand zones for confirmation.
\Limitations\
* The optimizer search range is fixed at 50…200 with step 5 for simplicity/performance. Adjust start\_length / end\_length / step\_length in code if you need a different space.
* Lines are rebuilt each update; many instances or very long histories can add overhead on weaker machines.
* This is a contextual tool, not a definitive buy/sell signal.
\Recommended settings\
* Many crypto pairs work well on 15m to 4h for a good balance of noise vs. signal.
* In strong trends, increase Multiplier or demand structural confirmation before fading an outer band.
* In ranges, focus on outer-band reactions with low local density and seek quick re-entries.
\Compatibility\
* Pine Script v5. Uses max\_lines\_count=500. When running multiple instances, monitor performance.
\Disclaimer\
* This is for analytical/educational purposes only and does not constitute financial advice. Use at your own risk.
