Hi fellow algo traders,

I'm fairly new and have a question: I'm not sure what exactly is meant with leverage in the Z8/Z9 system.
Of course I know what leverage is in general, but specific to these systems I'm a bit puzzled.

Is meant a specific type of derivative (e.g. leveraged etfs like QLD) or how is it possible to leverage a stock/etf ?

For example I have set up an IB account (margin) but I'm not able to set a leverage when buying/selling a stock/etf.
At least I don't see any options for that...

Greetings
