The Z8 Assets file uses Assets with a Leverage value of 4. Now by googling I found conflicting information about the actual leverage/buying power that IB offers for a RegT Margin account.

It seems like its not 4:1 but rater 2:1 for overnight positions. At least this seems to be the case in the US but im not sure.

Has anyone experience with this? What is the situation in Europe? Is it different for a Portfolio Margin Account?

Can I simply trade Z8 as is or do I have to change the values in the Assets list to reflect the correct Leverage?
