TT Iceberg

A TT Iceberg order executes a large volume order by breaking it into smaller disclosed orders, publicly displaying only the specified portion instead of the full order quantity. When one disclosed portion fills, the next portion is entered into the market. This process continues until the order is filled.

For more information, refer to the TT Iceberg Order section of the Trade help.

	OrderType Tag 40	tt_net_sdk.OrderType	TRUE	FALSE	OrderProfile	Order Type for native child order. This is always a limit order.

7	DiscValType Tag 16905	tt_net_sdk.tt_iceberg.DiscValType	TRUE	TRUE	UserParameters	Disclosed quantity type
8	Variance Tag 16958	Int_t	FALSE	FALSE	UserParameters	Quantity variance
2	LimitPrice Tag 44	Price	TRUE	TRUE	OrderProfile	Limit price to be used for native child order
9	LimitTicksAway Tag 16912	Int_t	FALSE	TRUE	UserParameters	If provided, overrides LimitPrice and sets the native child order price to be LimitPriceType-LimitTicksAway for buys and LimitPriceType+LimitTicksAway for sells.
10	LimitPriceType Tag 16911	tt_net_sdk.tt_iceberg.LimitPriceType	FALSE	FALSE	UserParameters
12	WithATickType Tag 16921	tt_net_sdk.tt_iceberg.WithATickType	FALSE	FALSE	UserParameters	If provided, sets the threshold for the With A Tick behavior that reprices the child order one tick toward the market when available quantity at the opposite inside market is at or below the specified quantity threshold.
11	WithATick Tag 16922	Int_t	FALSE	TRUE	UserParameters
15	TriggerPrice Tag 99	Price	FALSE	TRUE	OrderProfile	If provided, sets the parameters of a trigger which must be activated before the Iceberg portion of the algo will be executed. If IsTrlTrg=TRUE, the trigger will trail instead of being static so TriggerPrice will be ignored.
14	TriggerType Tag 16920	tt_net_sdk.tt_iceberg.TriggerType	FALSE	FALSE	UserParameters
16	TriggerPriceType Tag 16918	tt_net_sdk.tt_iceberg.TriggerPriceType	FALSE	FALSE	UserParameters

19	ParentTIF Tag 16950	tt_net_sdk.tt_iceberg.ParentTIF	TRUE	FALSE	UserParameters	Time in force for parent synthetic order
20	ETime Tag 126	UTCTimestamp_t	FALSE	TRUE	UserParameters	If ParentTIF is set to Time, ETime defines the end date/time and ETimeAct defines the end time action. If the ETimeAction is set to GoToMarket and ETAGoToMktTicksEnabled is set to True, then ETAGoToMktTicks defines the number of ticks through the market that a limit order will be submitted through market.
21	ETimeAct Tag 16906	tt_net_sdk.tt_iceberg.ETimeAct	FALSE	FALSE	UserParameters
