Part Two continues with a demonstration of using the process outlined in Part One to develop a system for trading the broad market US indexes.  The system is profitable in both rising and falling markets, and can be traded from Australia.  Key points include selection of the index to model, selection of the issues to trade, selection of fitness metrics, selection of holding periods, selection of entry techniques, selection of exit techniques, determination of in-sample period length, determination of out-of-sample period length, back-testing, optimization, walk-forward validation, estimate of trading profitability, and trading system life cycle management.
