If you optimize a variable from say 26 to 86, and the final value is 86, then means the range used to optimize is too narrow.

You could re-optimize and  try 56 to 106 for example.

The final parameter will appear in red, and the walk forward is not valid.


If you optimize a variable from say 26 to 86, and the final value is 80, but 86 is used in optimization range, then means the range used to optimize is too narrow.

The final parameter will appear in orange in this case.

It is recommend but perhaps not essential to use a wider range.


There would be an exception to this rule.

IF you code said if

entrytype=0 then ...stop entry

entrytype=1 then ...stop market

entrytype=2 then .. counter trend.

The fact that entrytype0 was chosen, does not imply we have reached the end if the parameters range in this case.


The more compen example where this applies is

result=rsi(close,x);

So if x = 86 like the example above, a larger number needs to be used.
