what is difference between sinput and input?

Question

i wish you best. what is actually difference between static input and normal input in MQL language? i mean sinput and sinput in the book that i read written that: "The value of a static input variable can be changed, but it cannot be optimized in the Strategy Tester. Static input variables are useful for logical grouping of input parameters." what does it mean exactly "it cannot be optimazed"? could you tell me a example please?

i can't undrestand the explanation and core difference.

Answer 1

sinput or static input simply excludes the variable from being able to have multiple different values tested when using the strategy tester.

You can find a more detailed explanation in the documents:
