After I use many single strategies to generate a portfolio, I export the portfolio to a .sqa format file, and then import it into databank of"simple strategies". I find that for the same portfolio, there is a big difference between databank of"simple strategies" and databank of "portfolio",for example the column of stagnation and the column of annual% return / max DD%.

The difference could be in Commission/Swap!? Try to uncheck this option on Loading dialog -> Advanced options while loading back the portfolio.
