Monte Carlo Forecast

Upload daily OHLC and simulate forward price paths. We infer a simple market regime from your candles, then run the same style of stochastic projection used in the VaultCharts desktop app.

How it works

Parse your CSV / JSON in the browser (nothing uploaded to our servers).
Infer regime (markup, markdown, accumulation, distribution, transition) from trend and range position.
Run hundreds of paths with ATR-based step volatility, phase drift, and mean reversion toward the recent mid-range.
Show the median path plus a 20–80% envelope for the next N sessions.

This is an exploration aid, not financial advice. Results change with each run because paths are random.
