TT With A Tick order

A With A Tick (WAT) order is a limit order that is automatically repriced one tick towards the market based on the price and quantity of the opposite inside market as follows:

• When best available price is more than one tick away from the limit price, the WAT order is repriced.
• If the best available price is one tick away and the available quantity drops below a specified threshold, the WAT order is repriced.

The WAT threshold is a parameter set by the user in one of two ways:

• Qty: The threshold is an absolute value. For example, you could place a buy order and join the best bid with a WAT threshold of 100. When the best ask quantity drops below 100, the buy order price will be repriced one tick higher.
• %: The threshold is a percentage of the WAT order quantity. For example, if the quantity on the opposite side of the market drops below 20% of your order's quantity, then your order will aggress into the market by one tick.

TT also allows you to add With A Tick behavior to all child orders of other TT Order Types, except for TT Trailing Limit.

  The quantity can be specified as:

  • % for a percentage of the initial quantity for this order
• Exch order type: The order type for the child order. (Currently, only Limit orders are supported.)
