What is a box setting?

Excuse me, could you please clarify what you mean by "box setting"? Is this a term related to cryptocurrency or finance specifically, or perhaps it's a more general concept that I'm not familiar with? In the context of finance, I'm not immediately aware of a direct meaning for "box setting," so I'm curious to know if you're referring to a specific strategy, tool, or configuration that's used in the industry. Could you elaborate a bit more on what you mean by this term, so I can provide a more accurate response?
