Order Entry Specs

This document describes the application level FIX messages used to submit and manage orders for equities, futures, and options, including single-leg and multi-leg variants.

This document is intended to be used in conjunction with the SpiderRock FIX Session Guide which describes session level message handling and other SpiderRock FIX conventions in more detail.

Please refer to the OrderManagement section of this site for more information about SpiderRock execution and order management algos and concepts.

Supported Order Types

DMA style orders - These are market or limit orders with a simple limit price and a designated exchange.

Smart/Sweep style orders - These market or limit orders, with a simple limit price, and no designated exchange. These orders will be routed to one or more exchanges at SpiderRock's discretion.

Algorithmic orders These are orders with complex algo behavior and complex price and size limits. They can both provide and interact with liquidity on any public exchange.

Multi-Leg orders - Also known as spread orders, these are orders to buy and sell orders with more than one option simulaneously. Multi-Leg orders can have DMA, Smart/Sweep, or Complex Algo style order handling. They can also work legs individually across all relevant exchanges.

Opening/Closing auctions - Orders designated for participation in either exchange opening or closing auctions.

Staged/Wait Start order management Most order types may be queued in SpiderRock systems until released by the client. These order types can be used to integrate client risk/approval systems with orders generated by trading groups. Alternatively, they can be used to integrate trader approval of orders generated by automated strategies. not sure

Note: Orders can be both staged in and released by any combination of SpiderRock GUI tools, the SpiderRock SRSE API, and FIX messaging.

Application Messages

NewOrderSingle (Client to SpiderRock)

NewOrderSingle<D> messages are used to submit orders for single securities. Both the standard order types and algorithmic order types offered by SpiderRock are communicated using this message.

In addition to standard FIX fields, SpiderRock uses custom FIX fields (5,000+) for SpiderRock specific parameters.

Example -- DMA

DMA orders are used to send a single order to a specific exchange or destination. This order type allows the client to control where the order is traded. Note that DMA orders may interact with dark liquidity in the SpiderRock platform if this is desired.

Note that orders can be released in multiple ways: via the SpiderRock GUI tools, the SpiderRock SRSE/SQL API, and a Listexecute<L> FIX message. Staged orders will be acknowledged immediately; fills will only be reported after the order has been released.

Algorithmic Order -- Option Autohedging Fields

If autohedging is enabled, then any resulting autohedge fills will be reported using the orders . Note that since autohedge trades are generated in response to option fills, perhaps over multiple orders, some accommodations must be made in the resulting autohedge execution reports. They cannot be reported back to the client on an order entry line; all autohedged drop reports are reported down a separate FIX drop line.

OrderCancelReplace (Client to SpiderRock)

The OrderCancelReplace<G> request is used to change the parameters of an existing New Order Single.

An ExecutionReport<8> with ExecType<150>=Pending Replace will be sent unless the OrderCancelReplace<G> can immediately be accepted (ExecutionReport<8> with ExecType<150>=Replaced) or rejected (OrderCancelReject<9> message).

An OrderCancelReplace<G> request will only be accepted if any associated child orders can successfully be cancelled. Requests that cannot be processed will be rejected with a CancelReject<3> message.

NewOrderMultileg (Client to SpiderRock)

A NewOrderMultileg<AB> message is used to submit an order for up to 6 option legs and one equity leg as a package. Both standard multi-leg order types and the more complex ones offered by SpiderRock are communicated using this message.

The NewOrderMultileg<AB> fields listed in the following table are used in common by all SpiderRock multileg orders. Additional fields are used by different order types to communicate their unique features. These fields are described in subsequent sections.

In addition to standard FIX fields, SpiderRock uses custom FIX fields (5,000+) for SpiderRock specific parameters.

DMA orders are used to send a multi-leg order to a specified exchange or destination. This order type is appropriate when the client wishes to control where the order is traded. Note that DMA orders may interact with dark liquidity in the SpiderRock platform if configured to do so.

MultilegCancelReplace (Client to SpiderRock)

The MultilegCancelReplace<AD> request is used to change the parameters of an existing New Order Single.

An ExecutionReport<8> with ExecType<150>=Pending Replace will be sent unless the MultilegCancelReplace<AD> can immediately be accepted (ExecutionReport<8> with ExecType<150>=Replaced) or rejected (OrderCancelReject<9> message).

An MultilegCancelReplace<AD> request will only be accepted if any associated child orders can successfully be cancelled. Requests that cannot be processed will be rejected with a CancelReject<3> message.
