AI Patterns

Multi-Model Pattern Detection

AI analyzes price action, volume, volatility, and market context to surface recurring patterns — so you focus on what matters, not noise.

Volatility

Stock Volatility Checker

See how wildly a stock actually moves — not just what it did yesterday, but what it is likely to do next. A storm gauge tells you if markets are calm, choppy, or dangerous.

Regimes

Market Regime Detector

Markets shift between calm rallies, choppy sideways drifts, and sharp selloffs. This tool detects which mode the market is in right now and where it is heading next.

Monte Carlo

Future Price Simulator

Simulate thousands of possible price paths for any stock. See the best case, worst case, and most likely outcome — so you stop relying on gut feelings.

Portfolio

Portfolio Optimizer

Find the ideal mix of stocks for your goals. Balance risk and return automatically — the same method pension funds and endowments use to manage billions.

Backtesting

Strategy Tester

Test any investment strategy against years of real market data before you commit real money. Built-in safeguards catch strategies that only look good on paper.

Factors

See the Risk Others Miss

Most investors check if a stock went up or down. This tool shows you how violently it could move tomorrow. Five different models measure risk from every angle, then a single storm gauge tells you whether conditions are calm, brewing, or dangerous — so you can act before the crowd reacts.
