Create orders from the Market Depth window by clicking the bid/ask at a specified price level. Be sure to confirm the order size before transmitting a Market Depth order.
The order size is based on default settings associated with the contract’s Preset. If the preset uses the Use cumulative size for Market Depth, the order size equals the cumulative size on that line x default order size. For example, if the default order size is 100 and you click the ISE $12.03 price level (below), the order size will be 10,600. If you click the same price level at the ARCA line, the order size will be 6,300. If the above box is not checked, the order size will be the default order size. You can modify the order size before transmitting the order.
