I have been unable to merge several stockpicking strategies into a portfolio in version 136 Dev. 3. I was informed by the Support Team that at this moment it is not possible to do that for stock picking.
In my opinion, this feature is essential in order to search what group of strategies compose the most balanced portfolios. Without this feature it is not possible to check, for example, the correlation between strategies.
Please, consider it for following development
Best regards.
