USDC/BRL Pair Update: New Tick Size Effective May 27
OKX is updating the tick size for the USDC/BRL trading pair. Starting May 27, 2026 (Wednesday), the BRL price precision will change from 3 decimal places to 4 decimal places.
What’s changing?
The tick size defines the smallest price increment allowed when placing an order. With this update:
**Before (3 d.p.): **prices were quoted as, for example, R$ 5.745
**After (4 d.p.): **prices will be quoted as, for example, R$ 5.7450
This means traders will be able to place orders with finer price granularity on the USDC/BRL pair.
Why does this matter?
Greater price precision enables tighter spreads between buy and sell orders, which can improve market liquidity and offer better execution conditions for traders.
What do you need to do?
**Open orders: **review your open orders on the USDC/BRL pair before May 27. Existing orders that do not conform to the new tick size may be adjusted or canceled automatically.
**Bots and APIs: **if you use trading bots or API integrations, update your price precision settings to 4 decimal places for the USDC/BRL pair before the change date.
**Manual trading: **no additional action is required. The platform will be updated automatically to accept the new precision.
When does it take effect?
The change will be implemented on May 27, 2026 (Wednesday). We recommend all traders prepare in advance to ensure a smooth transition.
