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.
