Executions are charged at 0.15 bps. BATS Europe also offers a dark self cross order type which allows participants to cross only against their own orders at the midpoint reference price, charged at 0.05 bps per side. BATS Europe uses two low-latency market data feeds to ensure an accurate midpoint is obtained during the course of trading.
