LS - Long or Short
This column identifies whether the strategy is Long or Short. The column will be blank for multi-systems, where the system may be a combination of long and short strategies.
You can specify whether to display long results, short results, or both long and short results by updating the View field in the Customize Results Listing dialog.
Note: The LS field will be blank for Multi-System results, since the multi-system may contain any combination of long and short strategies.
