I think that it would be better if, rather than being a set property of a strategy, the option of static/dynamic trade size was chosen by the user on following a strategy. Historic performance and backtests would use just static trade size or could be toggled between static and dynamic. This would allow more freedom of management by the user and prevent misrepresentation of historic performance for dynamic strategies caused by varying trade size.
Agreed. Static is not an option for me that I like
