Binance will update the tick size—the minimum price increment—for five USDⓈ-M Perpetual Futures contracts effective October 22, 2026 at 06:30 UTC. The adjustment aims to increase market liquidity and improve trading experience across BILLUSDT, IDOLUSDT, ESPORTSUSDT, BRUSDT, and AGTUSDT pairs. The tick sizes for BILLUSDT, IDOLUSDT, and ESPORTSUSDT will decrease from 0.00001 to 0.000001, while BRUSDT will shift from 0.00001 to 0.0001 and AGTUSDT will move from 0.000001 to 0.00001. API users can retrieve updated values via the GET /fapi/v1/exchangeInfo endpoint. Existing orders placed before the update will continue to match under the original tick size parameters.
