Margin is the collateral used to open and maintain leveraged positions.

When a position is opened, part of your collateral is reserved as margin.

Margin values change continuously based on:

If your Available Margin becomes insufficient, you may need to:

* Deposit additional collateral
* Reduce leverage
* Partially close a position
* Close the position
