What If Simulation è un fast and flexible cross-check introduced in Costruire 129. It allows users to simulate hypothetical execution scenarios without performing a new backtest.

Scopo

This tool applies predefined scenarios to the existing trade list from the main backtest to observe how strategy performance changes under alternate conditions, such as:

• Missing profitable trades
• Limiting trade execution to specific days or hours

Come funziona

• Scenarios are applied to the original trade list, without re-running a backtest.
• Modifications include:
  • Randomly skipping trades
  • Limiting trades to selected weekdays
  • Simulating partial trade execution

Because it does not require re-simulation, this cross-check is extremely fast.

Supporto per il filtraggio

You can configure filters to automatically reject strategies that deteriorate significantly in What If scenarios.

Esempio:

Filtrare qualsiasi strategia in cui What If Net Profit < 80% of original Net Profit.
