The TT® platform supports CBOE’s complex orders functionality. Using the Strategy Creation widget on TT, you can create and trade complex instruments for all options products at CBOE. The widget also supports sending an RFQ for the instruments you create.
Note: TT supports complex instruments with options legs only.
Creating a CBOE complex instrument on TT
When creating a CBOE complex instrument on TT, consider the following:
- CBOE reduces strategy ratios to the common denominator (e.g., 2×4 is sent to CBOE as 1×2).
- The exchange creates complex instruments with the Buy leg first regardless of the leg order submitted using the Stratey Creation widget. If a strategy is submitted with all Sell legs, CBOE creates the strategy with all Buy legs.
Complex instruments can be created with a minimum of 2 legs and a maximum of up to 12 legs using the Strategy Creation widget. Enter an instrument, ratio, and side for each leg.
When you click Create, the complex instrument is submitted to CBOE. When the instrument is created at the exchange, it appears in the execution report panel at the bottom of the widget with a “Status” of “Created”.
Submitting an order for a CBOE complex instrument on TT
In addition to displaying the CBOE complex instrument strategy in the Market Grid and opening an Order Ticket, you can click 
in the Trade column to open an Order Ticket and submit an order.
When submitting an order, consider the following
- Only Limit orders and Market orders with a TIF of IOC or Day can be sent for complex instruments.
- Complex orders are quoted in net price terms by combining the price and ratio of each leg.
- Complex instruments without working GTC orders are purged at the end of the trading day.
