The net value of your portfolio in a margin account. It is derived by taking your Long Market Value (LMV) minus any Short Market Value (SMV) adding any Margin Credit Balance (CR) or subtracting any Margin Debit Balance (DR). Options are not included as part of your LMV or SMV for margin equity purposes. However, options are included in the Margin/Option Equity Calculation.

Money Account Balances are not included in this calculation.
