11. Level II
To bring
up the level II window in OpenEx Pro, go to the menu bar Quote -> Level II or click on the toolbar icon. When you see the level II window pop up,
please enter your stock symbol in the Symbol field on the upper left hand
corner. The window will then load
streaming level II market information as Figure 11.1. A level II window includes the following components: the Level I Panel
on the top, the Level II Bid/Ask Panels in the middle, the Order Entry panel at
the bottom, and the Print section on the right.

Order Entry
To enter an order in the level II window, you just need to
perform a simple point and click action.
To populate the right information into your order entry box, you just
need to double-click on an entry in either the bid or ask panel. After that, you can click on the action
button Buy Sell Short to specify your desired action and submit the order. For example, in Figure 11.1, to buy MSFT at
price 57.86, one just need to double-click on the best Ask entry in the ask
panel, then the desired order information is loaded into the order entry box;
another click on the action button will submit the order. Please know that the color of the action
buttons and the frame of the order entry box will change according to the
action specified. Blue for Buy, Red for Sell, and Yellow for Short. The right color will be highlighted for
about half of a second and then get refreshed.
This design is to raise traders’ awareness of the action being taken.
Cancel Last
The action button 
is the Cancel Last button. Pressing it will cancel the last order you
send out from this order entry panel.
The Print section records all the real time transactions as they take place in the market. It scrolls from top to bottom. A green print means the transaction price is greater of equal to the best ask. A red print means the transaction price is lower or equal to the best bid. A white print means the transaction price is between the best bid/ask.
To hide the Print section, click on the blue triangle
circled in the red box in Figure 11.1.
To activate the Print section, click on that blue triangle again (Figure
11.2).
