Quote from MR.NBBO:
Any NYSE limit order that remains on the specialist's book longer than 5min. is billable. Yes, you can simply xcel/replace every 4:59...and not be charged. IB has instituted an automatic cancel replace for NYSE orders routed SMART. MB trading's MBTX route also automatically cancel replaces them for you. .01 is the standard charge billed to your brokerage firm ...and some firms pass those fees on.
It's billable after 2min on the AMEX, or any short order, or an order over 2100 shares. (AMEX).
