lotSz(step size) andminSz(minimum size) values post-update
Understanding Order Quantity Parameters
1. Step Size vs. Minimum Order Quantity
- Step Size: The smallest incremental/decremental unit for contract quantities
Example: For ETHUSDT perpetuals with 0.1 ETH contracts, a 0.1 step size means minimum price movements of 0.01 ETH (0.1 × 0.1 ETH). - Minimum Order Quantity: The smallest allowable contract amount, always a whole multiple of the step size
Example: With 1-contract minimums for SHIBUSDT (1M SHIB/contract), orders must be ≥1M SHIB. Post-update (0.1 step size), minimum becomes 100K SHIB.
2. Position & Order Display Rules
When step sizes become fractional (<1):
- Open positions show decimal contract sizes (e.g., 1.5 contracts = 1.5M SHIB)
- Pending orders display precise quantities (e.g., 10.5 contracts = 10.5M SHIB)
3. Order Processing Requirements
All new/modified orders must:
- Be integer multiples of the current step size
- Meet or exceed the updated minimum order quantity
API Compliance: Bot traders and copy trading systems must implement these validations.
4. API Interface Updates
The /api/v5/public/instruments endpoint and WebSocket channels will update:
lotSz(step size)minSz(minimum size)
