Mis à jour Quant Market Predictor v3 (No Signals)
Quant Market Predictor – Lite is a streamlined version of the full Quant Market Predictor model. This version focuses purely on market structure analysis and statistical forecasting, without generating trading signals.
The indicator combines multiple quantitative techniques commonly used in financial modeling to provide a clearer view of trend dynamics, volatility regimes, and short-term price projections.
It is designed for traders and analysts who want model-driven market context while making their own discretionary decisions.
Core Models
1. Kalman Filter Trend
A recursive Kalman filter smooths price data to estimate the underlying trend.
This approach reduces noise while remaining more responsive than traditional moving averages.
2. Adaptive AR(2) Price Model
An autoregressive model estimates short-term price momentum using recent price changes.
The coefficients adapt to volatility conditions to prevent overreaction during unstable markets.
3. GARCH-Inspired Volatility Model
A simplified volatility estimator tracks conditional variance similar to GARCH models.
This allows the indicator to identify high-volatility trend regimes and low-volatility consolidation regimes.
4. Multi-Bar Forecast
The AR model generates a short-term projection path for the next few bars.
The forecast gradually decays to reflect increasing uncertainty further into the future.
What the Lite Version Shows
• Kalman trend line (dynamic trend estimate)
• Volatility bands derived from conditional variance
• Regime background highlighting trend vs. consolidation environments
• Short-term statistical forecast path
• Information table displaying model diagnostics
Important
This Lite version does not produce buy or sell signals.
It is intended as an analytical tool to help interpret market conditions rather than a complete trading system.
Typical Use Cases
• Understanding whether the market is in a trend or mean-reversion regime
• Visualizing volatility expansion and contraction
• Viewing a probabilistic short-term forecast path
• Supporting discretionary trading decisions
