This rule creates a dynamic worth vary across the present market worth. Orders can solely be executed for liquidity inside that vary. If the value deviates considerably from its regular stage attributable to a flash crash, low liquidity, irregular market exercise, and many others., orders won’t be executed at that irregular worth.
To place it plainly, the mechanism that allowed Binance to print near-zero token costs throughout instances of maximum volatility shall be blocked earlier than any positions might be worn out.
Binance describes this as a “designed function” “To make sure that transactions happen at costs that mirror a good and orderly market.”
