Existing orders will not be canceled because of the adjustment, and users should take note of the following:
-
The tick size via API will also change and API users may use GET /api/v2/symbols exchange info for the latest tick size.
-
Open orders and historic orders will be displayed with adjusted tick sizes, rounding down for buy orders and rounding up for sell orders.
-
After the adjustment, existing orders, including those placed by API users, will still be filled according to the original tick sizes. (For example, if a tick size is adjusted from 0.0001 to 0.01, an order originally placed at the price of 130.2442 will be displayed as 130.24 but will still be filled at 130.2442.)
-
All the users (non-API users and API users) can no longer use the older tick size after the adjustment.
Please adjust your trading strategy according to the change to avoid unnecessary impact on your trading. We apologize for any inconveniences this may cause.
