OKX announced it will add four USD-margined X-Perp trading pairs—CXMTUSD, BSPUSD, TQQQUSD and UNITREE—across multiple trading services starting 16:30 (UTC+8) on October 12, 2026. The exchange warned that leveraged ETF X-Perps such as TQQQUSD already carry built-in leverage, and combining them with contract leverage further amplifies exposure and liquidation risk.
