Can I use this for walk-forward optimization?

Yes, it includes structured implementation patterns for both anchored and rolling walk-forward analysis to help you evaluate how a strategy might perform in live markets.

How does this skill help avoid backtesting bias?

It provides specific patterns for point-in-time data handling and rigorous out-of-sample testing protocols to prevent common pitfalls like look-ahead and survivorship biases.

Does it support realistic trading costs?

Yes, the framework includes implementation models for calculating slippage, fixed commissions, and variable transaction costs to ensure performance estimates are realistic.

What is the difference between event-driven and vectorized backtesting in this skill?

Event-driven backtesting is more realistic for complex order types and portfolio management, while vectorized backtesting is optimized for speed when evaluating simple strategy signals across large datasets.
