During a specific period of time (Freeze Time) before, during and after an economic event announcement (news) Pending Buy and Sell Stop orders cannot be placed, closed, deleted or modified. These restrictions apply to a single Buy/Sell Stop Pending order, as well as to opposite Buy/Sell Stop Pending Orders. By opposite (or ‘Corresponding’) stop orders we mean two stop orders (a Buy Stop and a Sell Stop) placed on the same currency pair, at the same time.
If you try to place, modify or close a Buy/Sell Stop Pending Order during the Freeze Time, you will see an error message in your TickTrader.
On the average, the Freeze Time period begins several tens of seconds before a news announcement, but its exact duration may vary depending on the nature and importance of the economic event.
According to the Definitions for Market Maker accounts:
Freeze Time – defined by Company the period of time before the event announcement. The Company has the right, at its sole discretion, to define the value of the Freeze Time depending on the situation on the currencies market and on the character of the event.
For more information, please, see the Terms of Business for Market Maker types of accounts: The Company can refuse opening, modification and deletion of all Pending Orders including Corresponding Pending Orders during the Freeze Time.
