Binance plans to complete changes to the order quantity step size for 23 spot trading pairs by 3:00 p.m. Beijing time on November 19, 2026, according to a Binance announcement reported by TechFlow on November 12. Step size is the smallest increment by which an order quantity can change.
Among the changes reported:
| Spot pair | Current step size | New step size |
|---|---|---|
| ETH/BTC | 0.0001 | 0.001 |
| SOL/BTC | 0.001 | 0.01 |
| LUNC/USDT | 0.01 | 1 |
| LUNC/USDC | 0.01 | 1 |
Binance said the adjustment would not affect spot trading or existing orders: orders submitted before the update would continue to be matched under the previous step size. The API step sizes will also change, so users running trading bots should adjust their order-quantity settings accordingly. The report does not list the other 19 pairs.
