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
