The Predictive Monte Carlo Engine is an AI-assisted indicator designed for retail trading charts to forecast future price movements using institutional-grade statistical models. It performs hundreds of Monte Carlo simulations based on historical volatility and return distributions to generate probabilistic future price paths. The engine supports three simulation models: Geometric Brownian Motion (GBM), Simple Random Walk (SRW), and Historical Simulation (HS), each offering different approaches to project price behavior. It visually overlays simulated paths on the chart, highlighting extreme percentile scenarios with color changes. An advanced dashboard displays key statistics including mean, median, maximum, and minimum projected prices. Additionally, it features a next-candle forecaster that provides an ASCII visual candlestick predicting the open, close, high, and low of the next price move based on simulation averages. This tool integrates quantitative finance techniques to provide dynamic target zones, risk boundaries, and statistical forecasts for upcoming price action.
