If a script includes a WalkForward section (not commented out), running it in single test mode will always use the variable parameter values as listed under WalkForward. To run such a script with constant parameter values, comment out the WalkForward section first.
A hand-written WalkForward section containing only a Dates line with two dates runs an explicit in-sample / out-of-sample split test; see In-Sample / Out-Of-Sample.
See spy_tlt_uis.rts in the Examples folder for an example that uses walk-forward optimization to implement a strategy from an article.
