I have been looking for a way to do a Walk-Forward Optimization (WFO) with trading systems I have created in Metastock.  Metastock has an Optimizer, but not a WFO.  The Add-on TrendMedium has one, but it only works with the trading systems that come with their add-on.  Does anyone know a WFO for Metastock or a coding technique that accomplishes the same thing?  It is much too time consuming to do it manually.
