You have the ability to place sweep orders on DOMTrader. This feature allows traders to place an order with a quantity totaling the aggregated depth quantity.
Go to Setup > Preferences > Order Placement > Order Placement Methods to enable sweep orders.
To place a sweep order
1. Click a quantity in the DOM column and drag it to the appropriate order column.
Before you release the mouse button, the order quantity and price are displayed like this:
The quantity is equal to the aggregate bid or ask depth (662 = 116 + 206 + 115 + 149 + 76). The quantity continues to update as long as you do not release the mouse button.
2. Release the mouse button. The order appears in the order column.
