Strategies on their own do not contain any filters referred to arrays of stocks. This means that strategy generates buy recommendations for a full set of stocks, satisfying strategy’s logic, and these can be dozens of symbols. To limit number of recommendations and make them most “convenient”, you can implement your own filter or use one of pre-defined filters.
Risk management is the most important part of overall portfolio management. Moreover, together with recommendations filter, it encapsulates your individual vision of portfolio behavior. While recommendation filter helps to chose “right” stocks, risk management, in fact, defines particular quantity of those stocks to buy or sell, which means it influences significantly on your portfolio structure. You can use one of pre-defined risk management settings or set your own ones, more or less speculative or protective.
