Margin Requirements and Exposure

Account-equity and session-boundary concepts for open-position valuation, collateral pressure, and overnight trading risk.

Margin exposure connects changing position value with the collateral and liquidity required to keep a leveraged trade open. Open Trade Equity measures unrealized gain or loss on marked futures and derivatives positions; Margin explains the account support required for securities and derivatives exposure.

An Overnight Position remains open across a session or account cutoff. Gaps, thinner liquidity, changing margin requirements, funding charges, and incompatible trading hours can make the next executable result differ materially from the prior mark.

Account review should keep ledger cash, open trade equity, net liquidating equity, buying power, and margin requirement separate. Each comes from a different calculation and should be reconciled to the broker, exchange, clearing, and contract records.
