Resting (maker) orders pay nothing; orders that take liquidity pay the fee. Formula: 9.5% × price × (1 − price) per share on orders that take liquidity (accounts under $10,000 of 30-day volume; 6.95% in a new account's first week and above $250,000). Break-even assumes you hold to settlement; trading out early pays the fee twice.
