I don't mean setting the leverage for a Universe I'm working with, but if I'm adding securities manually for example through self.AddEquity(), and I add let's say 10 securities through this, how do I make it so the algo works with just x1 leverage by default for all the securities? Or is the only way to manually set the leverage for each security that I'm adding?

By default the leverage is set to 2 for the IBKR model, how do I set the default to 1 instead?
