🧠 How it is calculated
The verdict combines trend (20/50/200 moving averages), momentum (RSI, MACD), mean reversion (Bollinger Bands), conviction (volume) and historical drift, weighted differently for each horizon. Uncertainty is modeled with a lognormal probability cone (geometric Brownian motion). This is statistical analysis, not a crystal ball.
