What is the ace 2 3 4 5 straight slang?

Excuse me, could you kindly clarify what is meant by the phrase "ace 2 3 4 5 straight slang"? I'm not entirely familiar with this particular terminology, especially in the context of cryptocurrency or finance. Is it referring to a specific type of market trend, a slang term used by traders, or perhaps a unique strategy in poker or card games? Could you elaborate a bit more on its meaning and how it might relate to our field?
