Possible values include:

• 3: Bank algo

Currently, TT supports only 1 (TT Order type).

Sets the order type for the parent order. Possible values for TT Premium Order /Types include:

• 1: Market
• 2: Limit
• 3: Stop Market
• 4: Stop Limit

Trigger price for a stop order. Only required when Tag 40 (OrdType) is:

• 3: Stop Market
• 4: Stop Limit

Time to start working the order.

Note: Omit to start working the order when submitted.

Some order types, such as TT Retry, support precision to the microsecond using a format YYYYMMDD-HH:MM:SS.sssmmm, where mmm represents the microseconds portion of the timestamp. When set, this precision is returned in the Execution Report.

Time to stop working the order.

Note: Omit to work the order until the market closes (GTD).

Maximum Participation with relation to the eligible volume.

Influences how strongly to tilt order trajectory (TT Close, TT Brisk), how tightly to track max participation (TT POV, TT Scale POV), or how tightly to follow an order schedule (TT TWAP+, TT VWAP+).

Determines the methodology used to tilt away from the a normal Volume-Weighted Average Price (VWAP)-based schedule for TT Brisk and TT Close algos.

Possible values include:

• Model Driven: Uses the instrument's liquidity and volatility profile to determine the strength of the tilt.

  This setting results in the tilt, compared to a normal VWAP schedule, being more pronounced with higher Aggression setting, higher instrument liquidity, higher instrument volatility, and longer order duration.

• Simple: The strength of the tilt is determined by the Aggression level and applied as a simple, linear shift vs a VWAP+ order trajectory. Higher Aggression levels will result in the order being shifted further away from VWAP+.

Allows trader to select between trend following and reversionary behavior.

Supported values include:

• AP-Revert-Low
• AP-Revert-Med
• AP-Revert-High
• AP-Trend-Low
• AP-Trend-Med
• AP-Trend-High

Specifies whether the order should get more aggressive when opposite side quote price is at the limit price.

This setting can be used to manage fill rate risk, increasing the expected fill rate if the market is nearing the limit price, at the cost of higher expected slippage on executed quantity.

Possible values include:

• Default (off)

• Aggressive More At Limit: When the opposite side quote price is equal to the limit price, the order will monitor liquidity conditions tick by tick and send extra IOC (Immediate or Cancel) orders to opportunistically take additional liquidity before the market runs away.

• Faster Near Limit: (Mild, Medium, Strong): In addition to the above behavior, the order will dynamically strengthen the tilt and trade faster as the market price approaches the limit price.

Price at which you would like to aggressively attempt to fill your order, regardless of the algorithm logic.

Order aggressively tries to fill if the instrument reaches this price, irrespective of volume based tracking objectives. Should be lower than limit and arrival time ask prices for BUY orders, higher than limit and arrival time bid prices for SELL orders.

When set to any value greater than 0, I Would Qty setting equals the minimum top of book quantity required before the order will cross the spread.

If greater than 0, an order will not cut or cross a bid-ask spread that is more than the specified amount wide.

Note This constraint takes precedence over I Would, With A Tick, Brisk Limit, and Cleanup % behaviors.

Enables the flip side of Stop Price functionality: if present, a Buy/Sell order activates once the Last Traded Price is less/greater than or equal to Trigger Price. Can be used in combination with Stop and Stop Limit orders for One-Cancels-Other (OCO) type behavior, where an order activates when the market reaches either a profit taking or stop loss price.
