    • 3 min interval — Price constraints are applied to the new child order based on the price of the earliest child order submitted within a rolling 3 minute window.
    • Lifetime — Price constraints are applied to the new child order based on the price of the initial child order submitted.

Price drift check example

Note: Price drift checks are only applied to synthetic orders.

Price drift checks are applied to a child order based on the price of the previous child order within a rolling time interval. In the following example, Ticks are set to "3" for a 1 min interval for the gateway login, and a user submits a 100 lot TT Time Sliced order configured to disclose 10 lot orders every 30 seconds with a relative price.

Based on the price drift check, the price of the newly submitted child order is checked against the price of the earliest child order submitted within the last minute:

  • For the 1st child order submitted, there are no previous child orders so the check is ignored.
  • For the 2nd child order submitted, the price of the previous child order is compared.
  • For the 3rd child order, the price of the 1st child order is compared (earliest child order submitted within the last one minute interval).

If the difference between the price of the earliest submitted child order and the new order price is outside the "3" tick range, the new child order will be rejected and the TT Time Sliced parent order will fail.
