The Minimum Price Increment (Tick Size) is the smallest increment by which the price of a contract can move.
A smaller Minimum Price Increment can theoretically lead to reduced bid-offer spreads, useful for price takers when crossing the spread to trade.
Lot Size
The Lot Sizes for the following contracts were reduced as shown below on 13 Nov 2025 at 04:00 UTC.
Perpetual swap | Current Lot Size (Contracts) | Lot Size (Contracts) starting 13 Nov 2025 04:00:00 UTC |
SOLUSDT | 1000 | 100 |
The Lot Size is an instrument's minimum trading unit (as number of contracts).
A smaller Lot Size means that traders can place orders with a smaller position size increment and participate in trading these contracts with smaller capital requirements. In the meantime, if you have any questions please contact Support.
