Now let’s think about how a seller might profit from understanding relative demand. Consider a question every auction seller faces: When should you end your auction? You might think it makes sense to end your auction when demand is at its highest peak. Data show that demand on eBay is highest between 5:00 p.m. and 9:00 p.m. PST. So most sellers end their auction during this “happy hour,” when absolute demand is highest. 8:00 p.m.

You don’t want to end your auction when demand is highest—in absolute terms. You want to end your auction when relative demand is greatest. And when is that? On eBay it turns out to be 2:00 a.m.! Although there are far fewer buyers online at 2:00 a.m. than there are at 8:00 p.m., there are also far, far fewer auctions that end at this time. As a result, every auction that ends at 2:00 a.m. captures greater attention than auctions that end at 8:00 p.m.

จากประโยคข้างบน...
1.relative demand คืออุปสงค์อะไรคะ
2.demand on eBay is highest between... หมายถึงอะไรคะ
3.end your auction หมายถึงยุติการประมูลใช่ไหมคะ
4.in absolute terms ในที่นี่หมายถึงอะไรคะ
5.absolute demand คืออุปสงค์อะไรคะ
เท่าที่อ่านมาและพอสรุปได้ว่า การประมูลตอนตีสองได้รับความสนใจมากกว่าตอนสองทุ่ม ประมาณยิ่งดึกยิ่งดี?

ขอบคุณค่ะ
