Market Order
Simulated via aggressive limit price plus fill_or_kill, with no native market type
Market Order (Simulated)
SB Chain has no native market order type. A market order is simulated by combining an aggressive limit price with the Fill or Kill modifier — set the limit price far beyond the current market and fill_or_kill = true. The order executes immediately against the best available liquidity or is rejected entirely, and never rests on the book at an unintended price.
