The Limit Up-Limit Down (LULD) mechanism is intended to prevent trades in National Market System (NMS) securities from occurring outside of specified price bands.
To set this up in Sterling Trader® Pro, from the Level 2 Window, go to VIEW > SETTINGS
From the Level 2 Tab to the Market Makers Box and check Highlight Specific Market Makers.
From the Highlight Makers Window, SET the Symbol field: *
Set the Makers field: LULD
Press ADD
Without filtering you don’t see the LULD because it’s fairly outside of the market.
To filter your view, go to view/hide specific market makers.
Click filters, then choose LULD
Press ACTIVATE
Then you end up with only showing the LULD
