When you use Cross Margin, your total balance is considered as collateral for your position. However, only a portion of your balance is actually locked up as Margin, and the remaining balance is still available for other purposes, such as withdrawing funds or entering new trades.
Once the Initial Margin is set, the system will allocate additional Margin in batches equivalent to the Unrealised Loss each time the Maintenance Margin requirement is breached. Conversely, if the position is profitable, the system will release Margin from the position.
Position Margin can also be changed by:
- Manually adding or removing margin
- Funding going into and out of position margin
- Automatic system margin allocation
