        "description": "Live Monte-Carlo simulation for price and portfolio forecasting, computed on demand and reproducibly. The simulate endpoint runs a geometric-Brownian-motion simulation of an asset and returns the terminal-price distribution (percentiles, mean, probability of a gain); the probability endpoint returns the modelled chance of reaching a target price; the portfolio endpoint projects wealth over many years with periodic contributions (a retirement/savings projection); the path endpoint returns one sample price path. Every run is seeded, so the same inputs always give the same numbers. A forward-looking simulation engine, distinct from historical-statistics and option-pricing tools — it turns a drift and volatility into a distribution of outcomes.",
