The mathematical backbone of Mean Reversion strategies. 📉📈 Visualizing the Ornstein-Uhlenbeck (OU) process. Unlike standard Brownian motion (which models stock prices), the OU process models things that oscillate around a stable value—like volatility, interest rates, or the spread between two correlated assets in Pairs Trading. If you want to play with the θ and σ parameters yourself, just comment 'ORNSTEIN' and I'll send you the repository. 🐍🔥 ​The "Probability Cloud" (green) shows where the path could have gone, but notice how the realized path (white) is constantly fighting to return to the theoretical mean (blue). ​The equation at the bottom controls the battle: ​θ = How fast it reverts. ​μ = The long-term average. ​σ = The volatility. quant.dhawan   22w If you want to play with th…
