Tick size, contract size, and minimum order size are crucial elements in trading. Deribit is implementing these changes to improve the tradability of these pairs and generate more volume. New orders at non-conforming tick sizes, contract sizes, or minimum order sizes will be rejected after this change on 18 August 2026.
Due to the parameter changes all being reductions, and the multiples used, any orders that conform to the old specifications will also conform to the new specifications automatically. However, to avoid any unexpected behaviour moving forward, traders would still be wise to update their systems in a timely manner to account for the new contract specifications.
Please note that these changes will apply to all new & existing orders but will not affect existing positions.
