Users can limit the contribution of their order to overall average daily volume in order to minimize impact. Clients can set a value between 1-50% to control their participation between stated start and end times. Order quantity and volume distribution over the day is determined using the target percent of volume you entered along with continuously updated volume forecasts calculated from TWS market data. In addition, the algo can be set to avoid taking liquidity, which may help avoid liquidity-taker fees and could result in liquidity-adding rebates. By checking the Attempt to never take liquidity box, the algo is discouraged from hitting the bid or lifting the offer if possible. However, this may also result in greater deviations from the benchmark, and in partial fills, since the posted bid/offer may not always get hit as the price moves up/down. IB will use best efforts not to take liquidity when this box is checked, however, there will be times that it cannot be avoided.
The Reference Table to the upper right provides a general summary of the order type characteristics. The checked features are applicable in some combination, but do not necessarily work in conjunction with all other checked features. For example, if Options and Stocks, US and Non-US, and Smart and Directed are all checked, it does not follow that all US and Non-US Smart and direct-routed stocks support the order type. It may be the case that only Smart-routed US Stocks, direct-routed Non-US stocks and Smart-routed US Options are supported.
