RegLin Polinomico

RegLin Polinomico

RegLin Polinómico is a professional indicator that fits a polynomial (degree 1, 2, or 3) over a rolling price window and builds dynamic bands from the standard deviation of the fit’s residuals. It includes RSI (with selectable timeframe) and a trend-only option to filter out low-quality breakouts. You can also enable/disable sound when visual signals (arrows) are generated.

How it works

• Fits a configurable-degree polynomial over RegPeriod bars.

• Draws the central curve (regression) and two bands at StdDevFactor standard deviations.

Indicative signals

• Buy: when the bar’s low breaks below the lower band and RSI confirms oversold.

• Sell: when the bar’s high breaks above the upper band and RSI confirms overbought.

• With OnlyInTrend = true , the slope must favor the trade (polynomial derivative): buys only if the slope is positive, sells only if it’s negative.

• If EnableSound = true , a sound plays when an arrow is drawn for the first time.

Polynomial degree: what changes and when to use each one

Degree 1 (Linear) – Trend-following & robust

• Behavior: best-fit straight line; delivers a clean read of direction.

• When: clear trends or mid/high timeframes (M15–H4).

• Pros: low latency, fewer false signals in orderly markets, less overfitting.

Degree 2 (Quadratic) – Curvature & cycles

• Behavior: allows curvature, capturing accelerations/decelerations.

• When: cyclical phases or arcing channels; changes of pace.

• Pros: balanced sensitivity vs. stability; detects broad turns better than linear.

Degree 3 (Cubic) – High sensitivity & inflections

• Behavior: captures inflections (convexity changes) and early turns.

• When: intraday/scalping and volatile instruments.

• Pros: maximum adaptability; consider tighter RSI/period and OnlyInTrend to avoid over-signaling.

Quick tip

• Start with Degree 1 to map the baseline trend.

• Try Degree 2 if you observe curvature.

• Use Degree 3 on lower timeframes / highly dynamic markets with stricter filters.

Key advantages

• Statistically consistent bands: width responds to model error, not just fixed ranges.

• Integrated technical filter: RSI and (optional) slope reduce deceptive breakouts.

• True market adaptability: switch degree by regime (trend, cycle, volatility).

• Refined UX: arrows with optional sound, bar-close confirmation to avoid repainting.

External variables (quick guide)

• RegPeriod – Number of bars for the fit and bands. Larger = smoother; smaller = more responsive.

• StdDevFactor – Standard-deviation multiplier of residuals (band width).

• PriceType – Price source: 0=Close , 1=Open , 2=High , 3=Low , 4=Average (O+C)/2 , 5=Typical (H+L+C)/3 .

• PolyDegree – Polynomial degree: 1 (linear), 2 (quadratic), 3 (cubic). Controls sensitivity & curvature modeling.

• RSIPeriod – RSI period used as a filter.

• RSITimeframe – RSI timeframe (enables MTF confirmation).

• RSI_Overbought / RSI_Oversold – Thresholds to validate overbought/oversold.

• RSI_Shift – RSI shift; use 1 to confirm on bar close and reduce repainting.

• OnlyInTrend – If true , requires slope in favor of the signal (derivative > 0 for buys, < 0 for sells).

• EnableSound – If true , plays a sound when a new arrow is drawn; if false , silent.

Summary

RegLin Polinómico blends statistical rigor with operational flexibility: it adapts model complexity to the market, filters with RSI/slope, and presents clear visual signals with optional sound. Built for traders seeking consistency, noise control, and an advanced read of price dynamics.
