On Tuesday 28 April, 2026, at 9 AM UTC, Deribit will implement changes to the tick sizes for 9 altcoin perpetuals. The tick size changes apply to both on screen orderbooks and block trades.
The change will impact the following Linear USDC perpetuals:
| Linear Perpetual | Current Tick Size | New Tick Size |
|---|---|---|
| ADA_USDC | 0.0001 | 0.00001 |
| ALGO_USDC | 0.0001 | 0.00001 |
| BCH_USDC | 0.01 | 0.001 |
| BNB_USDC | 0.05 | 0.01 |
| DOT_USDC | 0.001 | 0.0001 |
| NEAR_USDC | 0.001 | 0.0001 |
| SOL_USDC | 0.01 | 0.001 |
| TRUMP_USDC | 0.001 | 0.0001 |
| UNI_USDC | 0.001 | 0.0001 |
Tick size, the minimum increment by which the price of orders can change, is a crucial element in trading. Deribit is implementing this change to improve the tradability of these pairs and generate more volume on increased ticks. New orders that do not conform to the new tick sizes will be rejected as of 28 April 2026 9 AM UTC.
Due to the tick size changes all being reductions, and the multiples used, any orders that conform to the old tick sizes will also conform to the new tick sizes 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 tick sizes.
Please note that this change will apply to all new & existing orders but will not affect existing positions.
