A trading simulator for learning how your strategy behaves

Most traders don’t fail because they never ran a backtest—they fail because they never understood how a strategy behaves when the market stops cooperating. A trading simulator is the bridge between “backtest results” and “execution reality.”

Interactive trading simulator with speed controls for replaying historical market data

What simulation helps you see

• Signal timing: whether entries appear early/late in a move and how often signals flip.
• Execution sensitivity: how slippage and latency assumptions change outcomes.
• Regime brittleness: which market regimes break your logic (chop vs trend vs spikes).
• Operational feel: does the strategy trade too frequently, over-leverage, or cluster risk?

A practical simulation routine

1. Pick a period where your backtest drawdown was worst.
2. Replay at slow speed and watch entry/exit logic.
3. Increase realism (fees, slippage, latency) and observe changes.
4. Record what assumptions are required for the strategy to work.

Educational note: simulation is a learning tool, not a guarantee of future performance.
