Arrival Price Algo


This algorithmic order type will attempt to achieve, over the course of the order, the bid/ask midpoint at the time the order is submitted. The Arrival Price algo is designed to keep hidden orders that will impact a high percentage of the average daily volume. The pace of execution is determined by the user-assigned level of risk aversion and the user-defined target percent of average daily volume. How quickly the order is submitted during the day is determined by the level of urgency – higher urgency executes the order faster, but exposes it to greater market impact. Market impact can be lessened by assigning lesser urgency, which is likely to lengthen the duration of the order. The user can set the max percent of ADV from 1 to 50%. The order entry screen allows the user to determine when the order will start and end regardless of whether or not the full amount of the order has been filled. By checking the box marked Allow trading past end time the algo will continue to work past the specified end time in an effort to fill the remaining portion of the order.


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.

Additional Notes:

  • If Attempt Completion by End of Day is checked, we will try to complete the order today. Please note that we may leave a portion of the order unexecuted if the risk of the price changing overnight is less than the extra cost of executing the whole order today.

  • Get Done is more aggressive than the Aggressive selection. Neutral is slightly more aggressive than is Passive.
