Notes (For Non-Crypto Pairs)

• You cannot increase or open a new position within 30 minutes prior to market close, but you can reduce or fully close your position during this period.

• High-leverage positions (10x or above) are automatically closed 30 minutes before market close to prevent overnight exposure during off-market hours.

• During market closed hours, no trading activity is allowed - you cannot open, modify, or close positions. Unrealized PnL continues to update, but trading resumes only when the market reopens.
