How about the Relative/Pegged to Primary order-type? I have used them in the past and they're pretty neat. IB continually adjusts your order's limit price as the market moves. You can also set an offset to be a penny or more competitive than the market to help it fill quicker. The order type allows one to set a limit as well.?
