Margin is the amount of money that is required by the company to hold a position. Margin requirements are set by the exchange and differ by product.
As a company administrator, you can add or modify the exchange margin limits for each product and product type, including margin for inter-product spreads/strategies that have legs in more than one product or product type.
Note: A percentage of the margin can be applied per product when setting pre-trade risk limits for an account.
To set product margin limits, use the Company Settings | Product Margin tab in the left navigation pane. On this screen you can select one of more exchanges and use the Product Margin tab to set your margin requirements.
