Hi guys, trying to make sense of different IB order types: "Sweep-to-fill orders are useful when a trader values speed of execution over price. A sweep-to-fill order identifies the best price and the exact quantity offered/available at that price, and transmits the corresponding portion of your order for immediate execution. Simultaneously it identifies the next best price and quantity offered/available, and submits the matching quantity of your order for immediate execution." That is exactly what I expect a market order would do as well as a marketable limit order. So what is the difference to a sweep to fill? "A Market-to-Limit (MTL) order is submitted as a market order to execute at the current best market price. If the order is only partially filled, the remainder of the order is canceled and re-submitted as a limit order with the limit price equal to the price at which the filled portion of the order executed." This one sounds like a bad deal to me. Let's say I put in a limit order to buy at the bid. Assuming the price doesn't change I would get the bid price or better. A MTL is a market order at first so it would execute at the bid and not better than that, correct? Isn't MTL always worse than a limit order?
