I have attached two shots of the same strategy showing it with a walk forward matrix result and without. Optimizer has stopped showing any walk forward matrix results so I ran a strategy that had passed earlier to check and this time it also showed no results. The WFM result is from several days ago. Since then I have had no strategies produce any result in the WFM.
if yes, can you attach your SQ logs? they are placed in {StrategyQuant installation}\user\log\StrategyQuant folder
