Includes everything in NAL Tools.

NAL Systems moves from individual analytical components into complete systematic trading strategies.

Strategies are developed through a structured research process intended to investigate whether observed performance is robust, explainable, and capable of surviving conditions outside the exact historical sample used during development.

Depending on the strategy and research question, validation always includes techniques such as:

• Permutation testing
• Monte Carlo analysis
• In-sample / out-of-sample testing
• Parameter sensitivity analysis
• Trade-sequence analysis
• Drawdown analysis
• Regime analysis
• Robustness testing
• Alternative-market testing
• Transaction-cost assumptions
• Benchmark comparison

The objective is to distinguish a promising historical result from a strategy whose behavior has been examined from several independent statistical perspectives.
