Margin

Superstack supports cross and isolated margin. Unrealized PnL on cross becomes usable initial margin for new positions automatically. Isolated PnL stays with the isolated leg unless a user adds/removes margin. You can only withdraw/transfer margin if what remains is at least the greater of the initial margin requirement or 10% of total notional value.

The margin type can be selected upon opening or closing a position. A pop-up prompting the user will appear, asking whether cross or isolated is preferred.

NOTE: User cannot change margin mode on an open position.
