According to the announcement from Binance, the exchange will adjust the tick size, or minimum unit price change, of several USDⓈ-M Perpetual Futures Contracts on 2026-07-21 and 2026-07-22 to increase market liquidity and improve trading experience. The updated contracts include GMTUSDT, COTIUSDT, BATUSDT, DOTUSDT, ARPAUSDT and ALGOUSDT on 2026-07-21, followed by GWEIUSDT, TRIAUSDT, SAFEUSDT, HOMEUSDT, CTRUSDT and ACTUSDT on 2026-07-22. The tick size for GMTUSDT will change from 0.00001 to 0.000001 at 2026-07-21 06:30 (UTC), COTIUSDT will change at 2026-07-21 06:40 (UTC), BATUSDT at 2026-07-21 06:50 (UTC), DOTUSDT at 2026-07-21 07:00 (UTC), ARPAUSDT at 2026-07-21 07:10 (UTC), and ALGOUSDT at 2026-07-21 07:20 (UTC).

During the update windows, trading on GMTUSDT, COTIUSDT, BATUSDT, DOTUSDT, ARPAUSDT and ALGOUSDT will be suspended for one minute each, and users will not be able to place new orders, cancel orders or modify existing orders on those contracts. The exchange said each affected contract status will change from “TRADING” to “PENDING_TRADING,” and existing orders placed before the update will continue to match using the original tick size.
