Binance announced on its website that it adjusted the tick size—the minimum change in unit price—for selected USDⓈ-M Perpetual Futures Contracts on October 31, 2025, at 07:00 UTC, while maintaining uninterrupted trading operations.
According to Binance’s official announcement, the tick-size update is described as a measure to "increase market liquidity and improve users’ trading experience" across USDⓈ-M Perpetual Futures Contracts. The notice emphasizes that the adjustment will not impact USDⓈ-M Futures trading operations, meaning that trading continuity and system functioning remain the same. It further clarifies that existing orders placed before the update will continue to be matched using the original tick sizes—thus shielding already-placed positions from the change.
The change will affect multiple trading pairs including UBUSDT (tick size 0.000001 → 0.00001), RECALLUSDT (0.00001 → 0.0001), ACXUSDT (0.0001 → 0.00001), ZKJUSDT (0.0001 → 0.00001), PARTIUSDT (0.0001 → 0.00001), TOKENUSDT (0.00001 → 0.000001), NOTUSDT (0.000001 → 0.0000001), GPSUSDT (0.00001 → 0.000001), and PROMPTUSDT (0.0001 → 0.00001). These adjustments reflect a recalibration of price increments for these contracts—shrinking tick size in some cases to allow finer pricing resolution, and expanding in others to balance order-book structure.
