IB Margin settings?

[Dirk S 2]

For all US- members who use Interactive Brokers for their stock day trading: Which margin setting to you use?

I have  a choice between "Margin" and "Portfolio Margin",  the latter supposedly being more flexible but a minimum account balance of 100k

More to the point: if you are using "Margin" accounts, what margin % do you see? I will give you a few examples:

NNDM (very speculative)

XPEV (pretty speculative)

PG (very unspeculative)

SPY (market)
