Margin usage, reviewed beside performance
the margin ledger
Headroom's lived history as a review object: the days metric over time, its closest approaches to the floor, and the variation runs that drove them - read beside performance, per the seed, because an account can profit its way to the edge of forced selling and the P&L alone will never say so.
This lesson is part of the advanced modules.
Modules 6 to 8 are included with a paid account. The definitional summary above is the whole of this page until then.
