On the Accounts page, select an account and use the Limits tab to define position limits for the account. On this tab you can also configure risk for Block/Cross trades and Spread/Strategy risk limits for an account.
If configured, product limits apply to the aggregate trades of each sub-account (child account), as well as to any trades made using the parent account itself. If a limit is not set, then that limit is not considered as part of pre-trade risk checks.
You can also configure limits for interproduct Spreads and Strategies, which have legs in different products (e.g., GE and GLB) or different product types (e.g., a Future leg and an Option leg).
