How do I create an Accumulate/Distribute order?

Price Variant Percentage of Volume Strategy - This algo allows you to participate in volume at a user-defined rate that varies over time depending on the market price of the security. This algo allows you to buy more aggressively when the price is low and be more passive as the price increases, and just the opposite for sell orders. The order quantity and volume distribution over the time during which the order is active is determined using the target percent of volume you entered along with continuously updated volume forecasts calculated from TWS market data…

If you receive an order reject for a “Large Size” order you will need to recreate a new order for a smaller amount. Due to regulatory obligations, and in an effort to prevent sending orders to an exchange that would be disruptive to the marketplace, IBKR has implemented filters for "Large Sized" orders. These filters are based on the Average Daily Volume from the reporting exchanges. If your order is affected then the reject message will recommend a smaller amount for a new order that would fall within the "Large Size" order check parameters.     …

When you get the Large Order Size message you may not want to take the time to create and then edit additional individual orders. You can use the "Create Duplicate" feature in Classic TWS to create these orders for you. To use the "Create Duplicate" feature, start by creating a new order in Classic TWS and adjust the amount to a smaller quantity that will be accepted. Right click on the order row and select "Create" from the pop up menu (you may have to expand the menu by clicking on the small circle at the bottom). Select "Duplicate" from the side menu. This will create another separate order with the identical order details. After creating additional identical orders, you can transmit all of the orders at one time by going to the top of Classic TWS and clicking on the "Trade" menu followed by Transmit and "Transmit All Orders on Page" (or any of the other available choices). Please note, you can also use the "Create Duplicate" feature when right clicking on an order row for an open working order. …

Time Variant Percentage of Volume Strategy - This algo allows you to participate in volume at a user-defined rate that varies with time. Define the target percent rate at the start time and at the end time, and the algo calculates the participation rate over time between the two. This allows the order to be more aggressive initially and less aggressive toward the end, or vice versa…
