Practice decisions without risking capital
Replay hidden market history, trade synthetic future paths, and simulate portfolio outcomes with volatility-aware models.
Historical Replay
Trade through a real but undisclosed historical period. Predict the next day, manage positions, and reveal the dates only when the round ends.
Market Simulator
Generate future basket paths using bootstrap, correlated Monte Carlo, or heavy-tail models, then trade the synthetic market.
My Predictions
Run your threshold, cross-back-below, directional-bias, and four-band ThinkScript logic with historical replay, repeat steps, and undo.
Price Prediction
Compare bootstrap, block-bootstrap, correlated Monte Carlo, and heavy-tail Student-t projections at once, with bands, forward stepping, and one-step undo.
Portfolio Projection
Run hundreds or thousands of paths and compare terminal values, drawdowns, probability of profit, VaR, and expected shortfall.
Strategy Backtester
Test price-based stock and ETF rules with costs, benchmark comparison, drawdowns, monthly returns, and an exportable trade ledger.
Options Simulator
Build calls, puts, and multi-leg positions, then advance price, IV, Greeks, time decay, expiration, settlement, and account P/L.
Available simulation models
Each model answers a different question; none can predict actual returns.
