This is a very aggressive tactic that will hit bids/take offers that are better than your limit price, but will never post bids or offers. It achieves high participation rates. Note it is not a pure sweep and can sniff out hidden liquidity. As a result, it is often a better choice than placing a limit order directly into the market.
