Pre-trade risk limits are applied per product and are configurable per account and/or sub-account. In each case, the same product risk limits apply. Position limits per product or contract are configured only at the account-level.
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.
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).
Maximum position and order quantity limits are set as the number of contracts, lots, ticks, MW/h, etc., based on the product type and/or if it's an energy product that trades in flow.
Position limit settings in the General section are only applicable to accounts and if the risk settings apply to all products or contracts.
