Impulse Convexity Trend Gate [T1][T69]

OVERVIEW 🧭
• A price-only trend engine that opens a “gate” only when trend strength, acceleration, and impulse dominance align.
• Built from three cooperating parts: adaptive slope, directional convexity, and an impulse-vs-pullback ratio.
• Output is a bounded oscillator (−100…+100) plus side-specific gate states (bull/bear), with optional pullback and weakness highlights.
THE IDEA & USEFULNESS 🧪
• Not a simple mashup: each component plays a distinct role—slope for direction, convexity for acceleration agreement, and an impulse ratio to suppress correction noise.
• Adaptive EMA length (series-based) lets the midline adjust to conditions without external indicators.
• Approximation of hyperbolic tangent and clamp keep signals bounded and stable while avoiding library dependencies.
• Designed to help trend traders act only when continuation is likely, and stand down during pullbacks or chop.
HOW IT WORKS (PIPELINE) ⚙️
• Price transform
• Uses log price for scale stability.
• Adaptive midline
• Volatility-aware EMA length is clamped between minimum and maximum, then applied via a custom recursive EMA.
• Slope & convexity
• Slope (first difference of the midline) defines direction; convexity (second difference) verifies acceleration agrees with that direction.
• Impulse vs pullback ratio (R)
• Sums directional progress versus counter-direction pullbacks over a window; requires impulse to dominate.
• Normalization & score
• Slope and convexity are normalized by recent dispersion; combined into a raw score and squashed to −100…+100 using manual tanh.
• Trend gate
• Gate opens only when: R ≥ threshold, |normalized slope| ≥ threshold, and slope/convexity share the same sign.
• States & visuals
• Bull/Bear Gate Entry when gate is open, oscillator crosses ±15 in the correct direction, price is on the correct side of the midline, and slope/convexity agree.
• Pullbacks mark counter-moves while a gate is active; Weakness flags specific fade patterns after pullbacks.
FEATURES ✨
• Bull and Bear Gate Entries (green/red columns).
• Pullback shading and optional trend-weakness highlights (yellow/orange + teal/maroon).
• Background tint reflects the active side (bull or bear).
• Pure price logic; no volume or external filters required.
HOW TO USE 🎯
• Regime filter
• Trade only in the direction of the open gate; ignore signals when the gate is closed.
• Pullback entries
• During an open gate, wait for a pullback zone, then act on trend-resumption (e.g., oscillator re-push through ±15 or structure break in gate direction).
• Exits & risk
• Consider trimming when the oscillator relaxes toward 0 while the gate remains open, or when convexity flips against slope and R deteriorates.
• Timeframes & markets
• Suited for trend following on crypto/FX/indices from M30 to 4H/1D; raise thresholds on lower timeframes to reduce noise.
CONFIGURATION 🔧
• Impulse ratio gate (R ≥): raises/lowers the standard for continuation dominance.
• Slope strength gate (|sN| ≥): controls how strong a slope must be to count.
• Show Pullback Impulse (toggle): enable/disable pullback highlights.
• Show Trend Weakness (toggle): enable/disable weakness flags.
LIMITATIONS ⚠️
• As a trend tool, it can lag at regime transitions; expect whipsaws in tight ranges.
• Parameters are instrument- and timeframe-dependent; tune thresholds before live use.
• Pullback/weakness flags are contextual—not trade signals by themselves; use them with gate state and your execution rules.
ADVANCED TIPS 🛠️
• Tighten R and slope thresholds for lower timeframes; loosen for higher timeframes.
• Pair with NNFX-style money management and pair-level filters; let the gate be the confirmation layer, not the entry trigger by itself.
• Batch-test across 100+ symbols, export metrics, and run Monte Carlo to validate LLN reliability and Sharpe/IQR stability.
• For system hedging, disable entries when both sides trigger on the same asset to avoid internal conflict.
NOTES 📝
• Price-only construction reduces data-vendor differences and keeps behavior consistent across markets.
• Manual tanh/clamp ensure stable, bounded scores even during extremes.
DISCLAIMER 🛡️
• For research and education. No financial advice. Test thoroughly, size conservatively, and respect your risk rules.
