I’ve been looking through the various reports on the app, but it may be on the website portal I have not looked yet. I’m curious to find out how margin is assign by security, meaning if I borrow X, is it a waterfall approach to the loan from the highest $ position first or spread out pro rata across all positions? I do not see in the margin report how the margin balance is assigned by security.

I generally use margin to buy vehicles and my current margin balance could easily be covered by my largest position in the account.
