Combo Builder allows you to create multi-leg options strategies in a single order with atomic execution.
All legs execute simultaneously in the specified ratio, eliminating execution risk.
Specifications:
Legs: 2 to 4 per combo
Quantity: The absolute value of the ratio between legs must be less than or equal to 10. For example, you can have a ratio like 1:10 or 5:10, but not 1:11.
Instruments: Options. No perpetuals, no futures nor future rolls.
Size limits:
The total gross amount of the combo (order amount multiplied by the sum of absolute leg quantities) must not exceed:
- BTC options: max 25 contracts
- ETH options: max 1250 contracts
Tick size: Orders must respect the tick size for both amount and price, based on the tick size of the respective underlying.
