What is the benefit of using an event-driven backtester over a vectorized one?

Event-driven backtesters more accurately simulate real-world trading conditions, including order latency, partial fills, and complex order types, whereas vectorized backtesters are optimized for speed and simple signal testing.

How does this skill help prevent look-ahead bias?

The skill provides implementation patterns that strictly enforce point-in-time data separation, ensuring your trading logic only accesses information that would have been available at the moment of the trade.

Does this skill support walk-forward optimization?

Yes, it includes specialized patterns for walk-forward analysis, allowing you to test how a strategy performs on 'unseen' data windows to ensure its robustness across different market regimes.

Can I integrate custom transaction cost models?

Absolutely. The framework is designed to be modular, allowing you to plug in specific commission structures, slippage models, and tax considerations unique to your trading environment.
